Riga International Airport is the only major airport in Latvia, carrying around 5 million passengers annually. It is the largest airport in the Baltic states and has direct flights to over 80 destinations in 30 countries. It is also the main hub of airBaltic.

In the recent years airBaltic also operated from Liepāja International Airport as well as Ventspils International Airport but operations in both of these airports were ceased until 2017, when airBaltic relaunched flights from Riga to Liepaja.

Currently there are plans for further development in several regional airports, including Jūrmala Airport, Liepāja, Ventspils as well as Daugavpils International Airport.
