A direct flight quote that's $300 more than piecing two separate tickets together is exactly the gap Kiwi.com built its whole business around closing. Kiwi.com, founded in 2012 in Prague as Skypicker, is a flight booking platform using proprietary Virtual Interlining technology to combine flights across more than 700 airlines that don't otherwise have partnership agreements with each other.
The core idea is straightforward but genuinely different from Skyscanner or Google Flights: rather than only searching existing airline partnerships, Kiwi.com's algorithm books separate tickets on unrelated airlines and stitches them into one itinerary, often at a real price advantage. The tradeoff is worth understanding upfront — because the airlines aren't formally connected, travelers using this self-transfer routing are responsible for collecting and rechecking baggage between flights, and a delay on the first leg isn't automatically the second airline's problem. That's exactly what the optional Kiwi.com Guarantee is designed to cover, rebooking travelers onto a new connection if a self-transfer itinerary falls through. Beyond flights, the platform layers in trains, buses, price alerts, and a Nomad tool for multi-city trips where travelers are flexible on order. For travelers comfortable trading some itinerary complexity for meaningfully lower fares, that Virtual Interlining pricing advantage is the whole draw — though anyone with tight connections or zero tolerance for self-transfer risk may prefer paying more for a traditional single-airline itinerary. Before booking, it's worth checking this page for the current Kiwi.com discount code or coupon code — seasonal promos can meaningfully cut the final price.

💡 Shopping Tips
🛄 Add the Kiwi.com Guarantee on self-transfer itineraries with short layovers, since separate airlines won't rebook you for free if one leg is delayed.
💳 Choose the Flexi fare instead of Saver if there's any chance you'll need to cancel or change your trip.
