Sofia Airport (SOF) is Bulgaria’s main international gateway and the city’s primary hub for full-service carriers and low-cost airlines alike, so you’ll usually find a mix of flag carriers, European network airlines and budget operators. Located about 10–12 km east of the city center, transfer times are typically 20–30 minutes by taxi or ride‑share, and 30–40 minutes by metro (line M4) with fares generally in the low single-digit euro range. Bus services connect to central stations in roughly 30–50 minutes with very affordable fares. The airport is convenient for international connections and offers a decent range of shops and lounges, though peak times can be busy and facilities may feel compact compared with larger hubs.

While connecting options can sometimes be cheaper, a nonstop flight saves hours and offers a more comfortable, stress-free journey, making it the smart choice for business or leisure.

Bucharest is served mainly by Henri Coandă International (OTP), the city’s large international hub north of the center, and Aurel Vlaicu/ Băneasa (BBU), a smaller airport closer to town that often handles budget and charter flights. OTP is typically used by full-service carriers and many low-cost airlines, making it the main gateway for long-haul and regional connections; transfers to central Bucharest usually take about 30–50 minutes by car or express bus (40–70 RON for taxis, buses around 3–8 RON). BBU lies roughly 8 km from downtown and can be more convenient for short domestic or low-cost sectors, with tacitly lower fares on some routes. Pros: OTP offers more amenities and international connections; BBU can save time for quick trips. Cons: OTP can be busier and further out; BBU has fewer services and limited long-haul options.
