Buttons and links marked Kiwi.com are affiliate links. They pass through the Awin affiliate network, and if you book on Kiwi.com after clicking one, GateCast may earn a commission. Buttons marked Expedia are affiliate links too, through Expedia's own affiliate programme (run on Partnerize): if you book on Expedia after clicking one, GateCast may earn a commission. The hotel search on our connection pages and airport guides works the same way: it opens trivago through Awin, and GateCast may earn a commission if you book a hotel there.
Each result has one booking button. It goes to Kiwi.com unless the trip includes a Delta or Southwest flight, which Kiwi.com doesn't list (as of 7 October 2026). A trip flown entirely by Southwest goes to southwest.com, which is not an affiliate link and earns GateCast nothing; any other trip with a Delta or Southwest flight goes to Expedia, which sells them. A flight to or from an airport outside the US, on an airline whose international flights we have not yet seen Kiwi.com sell, also goes to Expedia: the button says “Search this route on Expedia” and opens a search for your route and date. Kiwi.com opens a search for your route and date, narrowed to around the flights you picked, southwest.com opens its own flight search for your route and date, and Expedia opens a search for your route and date (for one airline's trip, filtered to that airline, the number of stops and the times of day your flights leave and land, on one-way searches), so each can list other flights too. On a trip with two airlines, the Kiwi.com button says "See similar flights on Kiwi.com". Kiwi.com lists similar pairings; the exact pair may not be among them.
One thing to know about Kiwi.com
Kiwi.com sells some journeys as separate tickets. Kiwi.com's own guarantee may cover a missed connection on those, on its conditions; the airline is not obliged to rebook you. A GateCast grade rates the timing of a connection. It does not know whether your booking is one ticket or two. On separate tickets a missed connection is not rebooked by the airline. Check which kind of booking you are making before you pay.
What no link changes
A grade is worked out from schedules, delay records, airport layouts and airline rules. No airline or booking site can buy a better grade, and whether a link earns us a commission never changes a grade or the order of the results.
