FAQ

What does a flight comparison site like Skyscanner do?

Flight comparison sites search prices across airlines and online travel agencies, then show you the options in one place. You typically pick a flight on Skyscanner, KAYAK, or Momondo and then complete your booking with the airline or a third-party site.

Is it cheaper to book through Skyscanner, KAYAK, or Momondo?

These sites don’t usually sell you the ticket themselves — they show prices from airlines and booking sites. Sometimes they’ll surface deals you might not find on your own, but it’s not guaranteed to be the absolute cheapest every time. It’s smart to compare a couple of options and check the airline direct before you book.

Do these sites charge extra booking fees?

Skyscanner, KAYAK, and Momondo typically earn money from partners rather than by adding a fee on top of the price you see. However, some third-party booking sites they link to may charge their own fees. Always review the final breakdown on the site you actually use to book before you pay.
