Here you can compare different flights.

If you get the information about the desired flight, you will be able to book it directly with the airline or via an online travel agent. Google Flights, like Google, is merely a search tool. And, you are not buying flights from Google.

Google Flights collects its information straight from the databases of each airline. If you detect an inaccuracy, it's usually due to a fault of the airline's authority, not Google's. However, as ticket costs are continually changing, Google Flights may display an out-of-date price that has since changed owing to stored information. This is usually resolved within minutes if it is not seconds.

Nearly every single major (and several minors) airline is searchable via Google Flights, with a few notable exceptions. Southwest Airlines is the most notable airline absent from Google Flights.
