Kiwi.com review

Kiwi.com earns its place by building itineraries that standard searches leave out. Its US App Store listing says it searches thousands of carriers and also trains and buses, then uses three fare techniques: self-transfer trips that combine flights from different airlines, throwaway ticketing that shows a round trip when it costs less than a one-way, and hidden-city results with a layover in your real destination. The Kiwi.com Guarantee covers eligible bookings, and price alerts watch selected routes. These options can beat the cheapest fare elsewhere, but they shift work and risk to you: on a self-transfer trip you move between separate airlines yourself, and throwaway or hidden-city tickets mean skipping legs you paid for. Kiwi.com's 4.6 App Store rating from 37K ratings is the lowest in this list. Use it as a second search after a metasearch engine to see whether a combination saves enough. We compared documented features and published information; we did not book test trips.
