Altitude vs Google Flights, Kayak, Hopper, Expedia, TripAdvisor & Booking.com: The Definitive 2026 Comparison

Introduction

The travel planning landscape in 2026 looks nothing like it did five years ago. What was once a fragmented process of bouncing between airline websites, hotel aggregators, review sites, and spreadsheets is rapidly consolidating around AI-powered platforms that promise to handle everything in a single interface. But the reality is more nuanced than any marketing pitch suggests. Some platforms excel at search but cannot book. Others book everything but understand nothing about what you actually want. A few have bolted AI chatbots onto legacy infrastructure and called it innovation. And one -- Altitude -- was built from the ground up as an AI travel agent that plans, compares, and books entire trips through natural conversation.

This comparison examines seven platforms in rigorous detail: Altitude, Google Flights, Kayak, Hopper, Expedia, TripAdvisor, and Booking.com's AI Trip Planner. We evaluate each across more than 15 features, compare actual pricing, identify ideal use cases, and provide honest assessments of strengths and weaknesses. Whether you are a solo traveler optimizing for price, a family planning a complex multi-city itinerary, or a group of friends coordinating a trip from different cities, this guide will help you choose the right tool for the job.

The AI Travel Market in 2026: Context and Scale

Before diving into individual platform comparisons, it helps to understand the broader market forces driving this shift. The AI-assisted travel market has grown explosively over the past three years, and the numbers tell a compelling story about where the industry is headed.

In 2023, roughly 12% of leisure travelers under 40 reported using any form of AI tool during their trip planning process -- and most of that usage was limited to asking ChatGPT for destination suggestions. By 2025, that number had risen to 41% of leisure travelers under 40 using AI-assisted tools, according to Phocuswright's annual travel technology survey. That is a more than threefold increase in just two years, and it reflects not just curiosity but genuine utility. Travelers are discovering that AI tools can compress hours of research into minutes, surface options they would never have found manually, and handle the tedious coordination work that makes trip planning feel like a second job.

The global online travel market is valued at approximately $800 billion in 2026, with AI-assisted bookings representing a rapidly growing share. McKinsey estimates that AI-powered travel platforms will capture 15-20% of online travel bookings by 2028, up from roughly 3% in 2025. This is not a niche trend -- it represents a fundamental shift in how travelers discover, plan, and book trips.

Several factors are accelerating this transition. First, large language models have become dramatically better at understanding nuanced travel preferences. Saying "I want somewhere warm but not too humid, with good food, walkable, and under $2,000 all-in for a week" would have confused any AI system in 2023. In 2026, multiple platforms can parse that request and return genuinely useful results. Second, API infrastructure for real-time flight and hotel inventory has matured significantly. Platforms like Duffel, Amadeus, and Travelport now provide standardized access to hundreds of airlines and tens of thousands of hotels, making it possible for newer entrants to compete on inventory breadth without building decade-old supplier relationships. Third, consumer expectations have shifted permanently. After experiencing AI assistants in other domains -- shopping, customer service, content creation -- travelers increasingly expect their travel tools to understand them, not just search for them.

Feature Comparison: 15+ Dimensions

The following table compares all seven platforms across the features that matter most to modern travelers. We distinguish between full support, partial support (the feature exists but with significant limitations), and no support.

Platform Deep-Dives

A feature comparison table tells you what each platform does, but it cannot tell you how well it does it or what the experience actually feels like. The following deep-dives examine each platform's strengths, weaknesses, pricing, and ideal user profile in detail.

Altitude: The AI-First Travel Agent

Altitude was purpose-built as an AI travel agent -- not a search engine with AI features added, but a platform where the AI is the primary interface. You describe what you want in natural language, and the AI agent researches destinations, builds personalized itineraries, compares real-time prices across 500+ airlines and 10,000+ hotels through the Duffel API, and completes the booking through Stripe -- all within a single conversational interface. There is no moment where the planning and booking feel like separate products, because they are not.

The core differentiator is Altitude's 12-dimension scoring system. When the AI evaluates travel options, it does not just sort by price. It scores each option across 12 distinct dimensions including cost, travel time, layover quality, airline reliability, departure time convenience, seat availability, loyalty program alignment, hotel proximity, neighborhood safety, dining options, transit accessibility, and weather patterns. This means the AI can tell you that a $50 cheaper flight has a 6-hour layover in a terminal with no lounges during a historically high-delay window -- information that would take you 30 minutes to piece together manually.

Altitude's Waves feature is genuinely unique in the market. Waves enables group travel coordination where multiple travelers -- departing from different cities, with different budgets and schedule constraints -- can collaborate on a single trip. The AI finds flights that converge at the destination within a reasonable arrival window, suggests hotels with sufficient availability for the entire group, and presents per-person pricing breakdowns. This is not a multi-passenger booking form. It is coordinated multi-origin group planning with AI assistance at every step. No other platform on this list offers anything comparable.

Social features round out the platform. Travelers can share trips publicly or with selected friends, post trip reviews, and browse other users' itineraries for inspiration. The developer API and MCP (Model Context Protocol) server allow third-party tools and AI agents to search and book through Altitude programmatically -- a forward-looking feature that positions the platform for the emerging agent-to-agent ecosystem.

Strengths: End-to-end AI planning and booking in one interface. 12-dimension scoring that goes far beyond price comparison. Waves group travel with multi-origin coordination. Social features and trip sharing. Developer API and MCP server for programmatic access. Transparent pricing with published fee schedules. Real-time inventory via Duffel API with no stale pricing. Stripe-powered payment security.

Weaknesses: Price drop alerts and prediction are not yet available (coming soon). Newer platform with a smaller user base than established incumbents. No car rental booking yet. Hotel inventory, while extensive at 10,000+ properties, is smaller than Booking.com's or Expedia's massive databases.

Ideal user: Travelers who want AI to handle the entire planning and booking process, especially for complex trips. Groups coordinating travel from multiple cities. Travelers who value a personalized, conversational experience over manual search. Developers building travel-integrated applications.

Google Flights: The Gold Standard for Flight Search

Google Flights is, by virtually any measure, the best flight search engine available. It is fast, comprehensive, and completely free. Its Explore feature -- the interactive map that shows prices to destinations worldwide -- remains the single best tool for destination-flexible travelers. The calendar view with color-coded pricing makes it trivially easy to identify the cheapest travel dates. The tracking feature sends email alerts when prices drop for saved routes. And the integration with Google's broader ecosystem (Google Maps, Google Hotels, Google Calendar) creates a seamless research experience for travelers who live in the Google universe.

The limitations are significant, though, and they are all consequences of Google's business model. Google Flights does not book flights directly. When you find the fare you want, it redirects you to the airline or a third-party booking site to complete the purchase. That redirect introduces friction, price discrepancies (the fare may change between Google's cached result and the booking site's live price), and a fragmented experience. You lose the context of your research the moment you leave Google's interface.

More fundamentally, Google Flights is a search engine. It answers the question "What flights are available?" but it cannot answer "Where should I go?" in any meaningful way beyond showing you a price map. It has no concept of your preferences beyond basic filters (stops, airlines, bags, times). It does not build itineraries. It does not coordinate hotel bookings with your flight times. It does not handle group travel. It does not remember what you liked about your last trip. You provide structured inputs, and it returns structured results. Everything between those two steps is on you.

Google Hotels exists as a separate product that searches hotel inventory, but the integration between Google Flights and Google Hotels is minimal. There is no unified trip view, no bundle pricing, and no AI assistance in coordinating the two. You search for flights in one tab and hotels in another, and you coordinate them manually.

Strengths: Best-in-class flight search speed and comprehensiveness. Explore map for destination discovery. Price tracking and alerts. Completely free. Multi-city search support. Clean, fast interface. Enormous language support.

Weaknesses: No direct booking -- redirects to third parties. No AI planning or conversational interface. No itinerary building. No hotel integration with flight search. No group travel support. No social features. No loyalty program matching. No personalization beyond basic filters.

Pricing: Free. Google monetizes through referral fees from airlines and booking sites.

Ideal user: Experienced travelers who know exactly where they want to go and when, and who are optimizing purely for the cheapest fare. Destination-flexible travelers using the Explore map. Price-tracking enthusiasts willing to wait for deals.

Kayak: The Meta-Search Powerhouse

Kayak occupies a unique position as a meta-search engine that aggregates results from dozens of airlines, hotels, and online travel agencies in one interface. Its core value proposition is breadth: rather than searching one airline or one booking site at a time, Kayak queries hundreds of sources simultaneously and presents a unified comparison. For travelers who want to be absolutely certain they are seeing every available option, Kayak's comprehensiveness is unmatched.

Kayak's filtering and sorting capabilities are among the most powerful in the industry. You can filter by airline, number of stops, departure time ranges, flight duration, layover airports, baggage allowance, and more -- and you can combine these filters in ways that most other platforms do not support. The "Best" sorting option, which balances price against convenience factors like flight duration and departure time, is a genuinely useful feature that most competitors lack. Kayak's Trips feature allows you to create saved itineraries and track prices across multiple components.

However, Kayak shares Google Flights' fundamental limitation: it is a search engine, not a booking platform. The vast majority of search results redirect you to a third-party site to complete the booking. Prices shown on Kayak may not match what you see on the booking site, and availability can change between the search result and the actual checkout. Kayak has introduced some limited direct booking capabilities through Kayak Booking, but the coverage is inconsistent and the experience varies significantly by airline and route.

Kayak has experimented with AI features -- the "Ask Kayak" chatbot was introduced in late 2024 -- but these features remain superficial compared to a purpose-built AI travel agent. Ask Kayak can answer basic questions about destinations and suggest routes, but it cannot build comprehensive itineraries, coordinate group travel, compare options across multiple dimensions, or complete bookings within the conversational interface. It is, in essence, a FAQ chatbot attached to a search engine.

Strengths: Broadest meta-search coverage in the industry. Excellent filtering and sorting options. Price comparison across dozens of sources simultaneously. Price alerts and tracking. Kayak Trips for itinerary organization. Available in 18 languages.

Weaknesses: Most results redirect to third parties for booking. No genuine AI planning capability. No group travel coordination. No social features. No loyalty program matching. No personalized itinerary building. Price discrepancies between search results and booking sites. Mobile app has gotten cluttered with ads and promoted results.

Pricing: Free to search. Revenue comes from referral fees and advertising. Promoted results can obscure genuinely best options.

Ideal user: Comparison shoppers who want to see every available option across all sources before making a decision. Travelers who enjoy the research process and want maximum control over filters and sorting. Budget travelers optimizing across multiple booking sites.

Hopper: The Price Prediction Specialist

Hopper has carved out a distinctive niche with its price prediction algorithms. The app analyzes historical pricing data, seasonal trends, and demand patterns to predict whether a given fare is likely to go up or down in the coming days and weeks. The recommendation to "buy now" or "wait" is genuinely useful for flexible travelers, and Hopper claims its predictions are accurate 95% of the time. The Price Freeze feature, which lets you lock in a price for a small fee while you decide, adds another layer of value for indecisive travelers.

Hopper books directly -- flights and hotels -- without redirecting to third parties. This is a meaningful advantage over Google Flights and Kayak, as it eliminates the price discrepancy and friction problems inherent in meta-search. The booking experience is smooth, and Hopper's "Cancel for Any Reason" add-on provides flexibility that most airlines do not offer natively.

The limitations are substantial, though. Hopper is a mobile-only platform with no desktop interface, which limits its utility for complex trip planning that benefits from a larger screen. Its inventory is more limited than Google Flights or Kayak, particularly for smaller airlines and international routes outside North America and Europe. There is no AI trip planning, no conversational interface, no group travel support, no social features, and no multi-origin coordination. Hopper also does not support multi-city itineraries, which makes it impractical for anything beyond simple roundtrip or one-way bookings.

Hopper's business model relies heavily on ancillary revenue -- Price Freeze fees, Cancel for Any Reason premiums, and bundled insurance products. While each of these can be individually valuable, they add cost layers that make it difficult to compare Hopper's total price against competitors transparently. A $300 flight with a $25 Price Freeze, $30 Cancel for Any Reason, and $15 insurance bundle is really a $370 commitment, and Hopper's interface does not always make this clear upfront.

Strengths: Best-in-class price prediction algorithms. Price Freeze feature to lock in fares. Direct booking without redirects. Cancel for Any Reason flexibility. Clean, intuitive mobile interface.

Weaknesses: Mobile-only -- no desktop interface. Limited airline and hotel inventory, especially for international routes. No AI planning or conversational interface. No group travel. No multi-city itineraries. No social features. Ancillary fees can obscure true total cost. English-language only.

Pricing: Free to use. Hopper adds markup to some fares and generates revenue from ancillary products (Price Freeze, insurance, CFAR).

Ideal user: Mobile-first travelers with flexible dates who want data-driven guidance on when to buy. Simple roundtrip or one-way bookings where price prediction adds the most value. Travelers who value cancellation flexibility.

Expedia: The Full-Service Legacy Platform

Expedia is the travel industry's 800-pound gorilla. As one of the oldest and largest online travel agencies, it offers the broadest inventory of any platform on this list: flights, hotels, vacation rentals, car rentals, cruises, activities, and bundled packages. If you want to book every component of a complex trip in one transaction, Expedia can probably do it. The "Bundle and Save" feature offers genuine discounts (typically 10-20%) when you combine flights, hotels, and cars in a single booking. For straightforward leisure travel where you know what you want, Expedia's breadth and bundling are hard to beat.

The platform's loyalty program, One Key, unifies rewards across Expedia, Hotels.com, and Vrbo, offering a compelling value proposition for frequent travelers within the Expedia ecosystem. Points can be earned on any booking and redeemed across all three platforms, and the tier benefits (Silver, Gold, Platinum) provide meaningful perks like room upgrades and late checkout at participating hotels.

Where Expedia falls short is in the planning experience itself. The interface is dense, cluttered with sponsored listings and upsells, and fundamentally structured as a form-based search engine. You fill in dates, destinations, and traveler counts, and you get a list of results sorted by price or "recommended" (which factors in Expedia's advertising revenue). There is no AI planning, no conversational interface, no personalized recommendations based on your preferences, and no intelligent coordination between flight times and hotel check-in. The bundle feature saves money but does not help you figure out what to book in the first place.

Expedia's pricing can be opaque. While bundle discounts are real, the platform also shows "strikethrough" prices that imply larger discounts than they actually represent, and the checkout flow includes numerous upsells (travel insurance, seat upgrades, airport transfers) that inflate the final price. The resort fee problem is particularly frustrating -- many Expedia hotel listings show a nightly rate that excludes mandatory resort fees, which are only revealed at checkout. This is not unique to Expedia, but the platform does less than competitors to surface these hidden costs upfront.

Strengths: Broadest inventory across all travel categories. Genuine bundle discounts (flight + hotel + car). One Key loyalty program across Expedia, Hotels.com, and Vrbo. Direct booking for everything. Car rental and activity booking. Cruise booking. Multiple language support.

Weaknesses: No AI planning or conversational interface. Cluttered interface with sponsored listings. Hidden fees (resort fees, taxes) not always shown upfront. Aggressive upsells during checkout. No group travel coordination. No multi-origin support. Customer service quality inconsistent. Strikethrough pricing can be misleading.

Pricing: Free to search. Revenue from booking commissions, advertising, and ancillary products. Bundle discounts typically 10-20%.

Ideal user: Travelers who want to book flights, hotels, cars, and activities in a single transaction with bundle discounts. One Key loyalty program members. Travelers who know exactly what they want and prefer a traditional form-based search over a conversational interface.

TripAdvisor: The Reviews-First Discovery Platform

TripAdvisor's strength has always been user-generated content. With over 1 billion reviews covering hotels, restaurants, attractions, and experiences worldwide, it remains the most comprehensive source of traveler-written reviews on the internet. For trip research and destination discovery -- "Is this hotel actually as nice as the photos suggest?" "What are the best restaurants in Lisbon?" "Is this tour worth the price?" -- TripAdvisor is an invaluable resource that no other platform on this list can replicate.

The platform has expanded significantly beyond reviews. TripAdvisor now offers hotel price comparison (aggregating rates from multiple booking sites), experience and tour booking through Viator (which TripAdvisor owns), restaurant reservations through TheFork (also TripAdvisor-owned), and forum discussions where travelers can ask questions and get advice from experienced visitors. The "Trips" feature allows you to save and organize destinations, hotels, restaurants, and activities into trip plans that you can share with travel companions.

TripAdvisor introduced an AI-powered trip planning feature in late 2025, but its capabilities remain limited. The AI can suggest itineraries based on destination and duration, but it does not book anything, does not coordinate flights, does not handle group travel, and does not maintain a persistent understanding of your preferences across sessions. It feels more like a content generation tool than a travel agent -- it produces suggestions that you then need to research and book elsewhere.

The biggest frustration with TripAdvisor is the advertising. The platform relies heavily on advertising revenue, and the experience has become increasingly cluttered with sponsored placements, promoted listings, and interstitial ads. Finding the organic, genuinely useful content requires navigating past multiple layers of paid placement. For flight booking, TripAdvisor redirects to third-party sites, offering no direct booking capability and the same price discrepancy issues as Google Flights and Kayak.

Strengths: Largest review database in the travel industry (1B+ reviews). Excellent for destination research and discovery. Viator integration for experience and tour booking. TheFork for restaurant reservations. Forum community for travel advice. Trips feature for organizing research. Hotel price comparison across multiple sources.

Weaknesses: No direct flight booking -- redirects to third parties. Limited AI planning capabilities. Ad-heavy experience with sponsored listings. No group travel coordination. No conversational interface. No loyalty program matching. No multi-origin support. Flight search is basic compared to specialized tools.

Pricing: Free to use. Revenue from advertising, sponsored listings, Viator commissions, and referral fees.

Ideal user: Travelers in the research and discovery phase who want to read authentic reviews and get community advice. Experience and tour seekers who want to book through Viator. Restaurant researchers using TheFork integration. Travelers who value user-generated content over algorithmic recommendations.

Booking.com AI Trip Planner: The Chatbot on Top of Inventory

Booking.com launched its AI Trip Planner in 2025, and it represents the most visible attempt by a legacy travel platform to integrate conversational AI into the booking experience. The chatbot allows you to describe your trip in natural language -- "I need a family-friendly hotel in Barcelona near the beach for a week in July" -- and it returns results from Booking.com's enormous hotel inventory. It can answer follow-up questions, refine searches based on your feedback, and link directly to booking pages for the properties it recommends.

The inventory advantage is significant. Booking.com claims over 28 million listings worldwide, including hotels, apartments, vacation homes, hostels, and unique properties. For accommodation-focused searches, the sheer volume of options available through the AI Trip Planner exceeds what any competitor can offer. The chatbot's integration with Booking.com's review system also means it can factor user ratings and review sentiment into its recommendations.

The limitations, however, are structural. Booking.com's AI Trip Planner is limited to Booking.com's own inventory. It does not search across multiple platforms, it does not compare prices against competitors, and it cannot tell you if the same hotel is available cheaper on the hotel's own website or on another OTA. For flights, the AI Trip Planner offers no capability at all -- Booking.com's flight search is a separate product that is not integrated with the chatbot. This means the AI can help you find a hotel but cannot plan a trip that coordinates flights, hotels, and ground transportation as a unified experience.

The conversational AI itself is competent but shallow. It handles simple preference-based searches well ("I want something quiet with a pool") but struggles with complex, multi-dimensional requests ("I need two connecting rooms near a subway station, under $200/night, with free cancellation, and ideally near a good Italian restaurant"). It does not maintain meaningful context across sessions, does not learn from your past bookings, and does not offer the kind of proactive suggestions (alternative dates with better pricing, nearby neighborhoods with better value) that a genuinely intelligent travel agent would provide.

Strengths: Conversational interface for hotel search. Access to Booking.com's massive 28M+ property inventory. Direct booking integration. Free cancellation on many properties. Genius loyalty program discounts. Review integration. 40+ languages.

Weaknesses: Limited to Booking.com's own inventory -- no cross-platform comparison. No flight booking or coordination. No group travel. No multi-origin support. AI capabilities are shallow beyond basic hotel search. No loyalty program matching beyond Genius. Separate flight product not integrated with AI. Cannot coordinate hotels with flight times or ground transportation.

Pricing: Free to search and use AI Trip Planner. Booking.com takes commissions from properties (typically 15-20%), which are factored into the prices shown. Genius discounts (10-20%) available for loyalty members.

Ideal user: Travelers primarily focused on finding accommodation who prefer a conversational interface over form-based search. Booking.com Genius members seeking loyalty discounts. International travelers who want a wide range of accommodation types. Travelers who value free cancellation policies.

Pricing Comparison

Understanding how each platform makes money helps explain their incentive structures and the true cost to travelers. The table below compares pricing across all seven platforms.

A note on transparency: Altitude is the only platform on this list that publishes its fee structure explicitly. Google Flights and Kayak appear free because they redirect booking to third parties, where the fees are built into the fare. Hopper, Expedia, and Booking.com embed their margins into the listed prices, making it impossible for travelers to know the exact markup. This is not inherently dishonest -- commission-based models are standard in the industry -- but it means "free" platforms are not truly free. The cost is simply hidden in the fare or room rate.

Who Should Use What: The Expanded Guide

Every platform on this list serves a purpose, and the right choice depends on what you need. Here are specific use cases matched to the best tool for the job.

Use Google Flights if you already know your destination and dates and you are optimizing purely for the cheapest available fare. Google Flights is also the best tool for destination discovery when you have flexible dates and an open mind -- the Explore map remains unmatched. If you enjoy the research process and want maximum control, Google Flights gives you the data. Just know that you will be doing all the planning and coordination work yourself.

Use Kayak if you want to see every available option across every booking platform before making a decision. Kayak's breadth is its superpower. If you are the kind of traveler who checks five different sites before booking anything, Kayak lets you check all five from one interface. It is also the best tool for complex filtering -- if you need a direct flight departing between 6 AM and 9 AM on a specific airline with checked bag included, Kayak's filters will find it faster than anyone else.

Use Hopper if your dates are flexible and you want data-driven guidance on when to buy. Hopper's price prediction algorithms are genuinely best-in-class, and the Price Freeze feature adds unique value for travelers who are not ready to commit. If your use case is a simple roundtrip flight and you want the app to tell you "buy now" or "wait three days," Hopper delivers that experience better than anyone else. Just be aware of the ancillary fees that can inflate the total cost.

Use Expedia if you want to book every component of your trip -- flights, hotels, cars, activities -- in a single transaction with bundle discounts. Expedia's breadth across travel categories is unmatched, and the One Key loyalty program provides real value for frequent travelers. If you know what you want and you want to book it all in one place with a single confirmation email, Expedia is efficient. Just budget time for navigating the upsells.

Use TripAdvisor if you are in the research and discovery phase of trip planning. When you want to know if a hotel lives up to its photos, what the best restaurants in a city are, or whether a particular tour is worth the price, TripAdvisor's billion-plus reviews are an irreplaceable resource. Pair TripAdvisor's research with another platform's booking capability for the best of both worlds.

Use Booking.com AI Trip Planner if you are primarily looking for accommodation and you want a conversational interface to narrow your options. Booking.com's inventory is enormous, the Genius loyalty discounts are meaningful, and the AI chatbot handles simple preference-based hotel searches competently. If you have already booked your flights and just need a hotel, this is a solid choice.

Use Altitude if you want an AI agent to handle the entire trip planning and booking process from start to finish. Altitude is the right choice when you do not want to spend hours researching, comparing, and coordinating -- you want to describe your ideal trip and have the AI figure out the rest. It is the only platform on this list that handles group travel with multi-origin coordination, and the 12-dimension scoring system surfaces insights that would take significant manual effort to piece together. If you value your time more than the feeling of personal control over every search parameter, Altitude is built for you. It is particularly well-suited for group trips, complex multi-city itineraries, and travelers who want planning and booking in a single, coherent experience.

The Verdict

The travel platform market in 2026 is not a winner-take-all competition. Each tool on this list excels in its domain: Google Flights for flight search, TripAdvisor for reviews, Expedia for bundled bookings, Hopper for price prediction, Kayak for meta-search breadth, and Booking.com for hotel inventory. These are mature, reliable tools that have earned their place through years of iteration and billions of searches.

What Altitude brings to the table is a fundamentally different paradigm. Instead of searching, comparing, and booking as separate activities across multiple tools, Altitude collapses the entire process into a single AI-guided conversation. The 12-dimension scoring, Waves group travel, social features, and developer API are not incremental improvements on existing platforms -- they are capabilities that did not exist in the travel industry before Altitude built them. The question is not whether Altitude is better than Google Flights at flight search (it is not) or whether it has more hotel inventory than Booking.com (it does not). The question is whether the integrated, AI-first approach delivers a better overall outcome for the traveler. For a growing number of travelers -- particularly those planning complex, multi-component trips -- the answer is yes.

The best approach for many travelers in 2026 is a hybrid strategy: use Google Flights or TripAdvisor for initial research and inspiration, then bring your refined ideas to Altitude for AI-assisted planning, coordination, and booking. Or skip the research phase entirely and let Altitude's AI do it for you. Either way, the days of juggling six tabs and a spreadsheet to plan a trip are ending -- and that is good news for everyone.
