How it works
Six simple steps from "where should I go?" to "I'm booked." Everything runs in your browser — no app to install, no signup required to search.
1. Search live flights
Enter your origin, destination, dates and passengers. We query live data from hundreds of airlines and OTAs and show you results sorted by best, cheapest or fastest. Filter by stops, baggage, layover length, cabin class and more.
2. Ask the AI Assistant
Not sure where to go? Open the AI Assistant and describe your trip — 'a sunny week in October under $500'. It suggests destinations, dates and itineraries you can search instantly.
3. Plan your trip
Use the AI Planner to build a day-by-day itinerary with attractions, food picks and transit tips, customized to your travel dates and interests.
4. Save what you like
Bookmark interesting flights and itineraries. They sync to your account so you can compare options across devices before deciding.
5. Set a price alert
Pick a target price for any route. We watch the fare in the background and email or notify you the moment it drops below your threshold.
6. Book on the airline's site
When you're ready, tap 'Book' and we redirect you straight to the airline or partner. Kairos Fly never charges booking fees and never stores your payment details.
