Cheap flights from Warsaw to Sofia

September is the cheapest month on this route, and the price calendar shows the drop once the summer school holidays end and demand eases. October and November stay reasonable, and early winter is quiet apart from the Christmas and New Year rush, when fares climb and the Bulgarian ski season begins. Spring lifts prices again around Easter, and July plus the first half of August is the expensive stretch. Midweek departures, Tuesday and Wednesday in particular, usually cost less than Friday and Sunday flights. Book a few weeks ahead for summer travel and earlier for the holidays, and compare both Warsaw airports before you commit.

Ryanair and Wizz Air, including Wizz Air Malta, are the low-cost names you will see most often on Warsaw to Sofia, and they fly the route direct. LOT Polish Airlines, the Polish flag carrier, also serves it non-stop from F. Chopin. Sky Express and Sun Express turn up on some departures, while Lufthansa, Swiss, Austrian and Helvetic Airways generally mean a connection through a German, Swiss or Austrian hub. Budget and full-service tickets are not the same product, so compare what each fare includes rather than the headline figure: on the low-cost carriers extras are priced separately at booking, and full-service fares usually bundle more.

You land at Sofia Airport, the city's only airport and the main gateway to Bulgaria, on the eastern edge of the capital. It is close to the centre by the standards of most European capitals, and the usual ways in are a taxi, a ride-hailing app or public transport, with the metro and city buses both reaching the middle of town. Allow extra time on the way back: Sofia traffic is heavy at rush hour, and check the terminal shown on your booking before you set off. If you land late at night, arrange your transfer before you fly, since options thin out once the last buses and metro services have gone.
