Aviasales is a flight metasearch service. It searches fares from airlines, online travel agencies and ticket sellers, then shows results so users can compare prices, routes, flight times and stops.

Useful features include:

Searching for flights between specific cities and dates
Comparing offers from multiple sellers
Finding cheap destinations and low-fare dates
Setting price alerts and fare-drop notifications
Using the service on the web and through mobile apps

Aviasales does not usually sell tickets itself. When a user chooses an offer, the site redirects them to the third-party seller to complete the booking. The service is free for users; it earns money from partner referrals and advertising.
