What are the best flight search engines to use in 2026?
Google Flights for speed and flexible-date grids, Kiwi.com for creative multi-airline routings, Skyscanner for global fare coverage, and the airline direct site to confirm and book. OTAs like Expedia and Kayak lag on newest fares and complicate refunds — use for comparison, book direct.
Google Flights leads on speed, calendar heatmaps, and price alerts. Kiwi.com is unmatched for stitched itineraries across low-cost carriers (with the caveat that its Kiwi Guarantee replaces IATA-standard protection). Skyscanner casts the widest global net including regional carriers. Once you find the fare, book direct with the airline — OTA prices are usually the same or very close, and any refund or change goes through the airline directly rather than an OTA queue.
