Key Features
✓ Pros
- Ask AI (April 2026) — Full conversational booking interface. Ask follow-up questions, compare options, and refine searches without starting over. "Show me those flights but on a Wednesday instead" just works
- Real-time pricing — This is Kayak's core product, and the AI layer doesn't compromise it. Every price shown is live and bookable
- Multi-service comparison — Search flights, hotels, and rental cars in a single conversation. "Find me a flight to Barcelona, a hotel near the Gothic Quarter under €150/night, and a car rental for the weekend" returns all three
- PriceCheck — Upload a screenshot of a booking confirmation and Kayak tells you whether you overpaid and by how much. Useful for catching price drops within free cancellation windows
✗ Cons
- No itinerary planning — Kayak finds and books travel components, but it doesn't build day-by-day itineraries with activities and restaurants. Use it alongside a planner like Mindtrip or Wanderlog
- ChatGPT plugin version requires a ChatGPT Plus subscription ($20/month). The native Kayak Ask AI is free
- No offline access — requires internet for every search
Full Review
Kayak launched AI Mode in October 2025 and followed with Ask AI in April 2026, turning the metasearch engine into a conversational travel assistant. Instead of filling out form fields (origin, destination, dates, passengers, class), you type "cheapest flight from Chicago to Lisbon in October, flexible dates, window seat" and get real results with real prices. It's Kayak's existing search inventory — one of the largest in travel — accessible through conversation instead of dropdown menus.
