Cheap Flights from Frankfurt to Sofia — $20

Frankfurt Airport (FRA) is Germany’s primary international hub and a major European transfer point, serving a mix of full-service carriers, long-haul operators, and some regional services; low-cost airlines also use secondary terminals at times. Located about 12–15 km west of the city center, the airport is well connected by high-speed regional and S-Bahn trains (15–20 minutes to central Frankfurt), long-distance ICE services (20–30 minutes) and frequent regional buses and taxis; expect public transport fares in the low single-digit euros to low double digits for taxi rides. Advantages include extensive lounge and shopping options, strong transfer infrastructure and many long-haul choices; downsides can be busy terminals, occasional queues and a spread-out complex that may require extra transfer time between terminals.

Located about 10–15 km east of the city centre, travel times are usually 20–30 minutes by taxi or 20–30 minutes on public transport: the metro connects the airport to central Sofia in roughly 18–25 minutes with fares around a few leva, while buses and taxis can vary by traffic and cost. The airport is generally convenient for quick access to the city and offers a compact layout for shorter transfers, though peak times can feel busy and some services may be limited compared with larger European hubs.
