Top sites to book flights

Aviasales is one of the most popular flight metasearch engines in the world, and it's our top pick for tracking down the cheapest fare. Rather than selling tickets itself, it scans hundreds of airlines and online travel agencies in a single search and shows you who has the lowest price.

What really sets it apart is the whole-month price calendar and free price alerts: set your route, watch the fare, and book the moment it drops. It's especially powerful for flexible travellers, one-way hops and complex multi-city itineraries.

Trip.com is a global travel super-app that's particularly strong across Asia. You can book flights, hotels and even trains in one place, which is genuinely convenient for multi-leg trips where you'd otherwise juggle several sites.

It runs frequent flash sales and a Trip Coins loyalty scheme that quietly discounts future bookings, backed by 24/7 multilingual support — reassuring when plans change at short notice.
