Kiwi

Kiwi is a flight search engine that scours hundreds of airlines — including budget carriers — to find cheap tickets, often combining segments from different airlines in ways you won't see on other booking sites. It’s built for travelers who want flexibility: you can search by city, airport, or even just a region, and the tool will stitch together itineraries that might include a bus ride or a train between flights. The latest addition is AI Mode, a beta feature that lets you describe your ideal trip in plain English (think “sunny beach destination under 200 euros in September”) and get suggestions instantly.

The platform stands out for its travel protection. The Kiwi.com Guarantee covers automatic check-in for many airlines, rebooks you on alternative flights if you miss a connection, and issues instant credit if a flight is canceled. There’s also a loyalty program called Kiwi.com Club that unlocks member-only fares and periodic Voucher Drops worth up to 500€. You can set price alerts, manage all bookings in one place, and get personalized support through the app or website.

Who is Kiwi for? Mostly budget-conscious travelers who don’t mind unconventional routes to save money, and frequent flyers who want a single interface to compare options across dozens of airlines. It’s especially useful for planning multi-city trips or last-minute getaways. The AI Mode is still in beta but already makes the search process more conversational — a nice touch for spontaneous explorers. Just be aware that because Kiwi combines non-protected connecting flights, the Guarantee is essential if you book an unorthodox itinerary.
