Bucharest is mainly served by Henri Coandă (OTP), the capital’s international gateway and busiest airport, and Aurel Vlaicu/ Băneasa (BBU), a smaller airport that can be used for some budget or charter flights. Henri Coandă typically handles full-service carriers and many low-cost operators too, while Băneasa is more commonly linked with domestic or short-haul budget services. Henri Coandă sits about 16–18 km north of the city centre; travel options include express trains or regional rail (roughly 20–40 minutes), airport shuttles and taxis (30–50 minutes depending on traffic), with fares ranging from modest rail fares to mid-range taxi or rideshare prices. Băneasa is closer, around 8–10 km from central Bucharest, reachable by bus or taxi in 15–30 minutes and often cheaper for quick transfers. Pros: Henri Coandă offers more international connections and facilities, while Băneasa can be quicker to access for northern neighbourhoods. Cons: both can be affected by peak-hour congestion and transfer times may vary; budget-conscious travellers should compare fares and transport choices in advance.

Sofia Airport (SOF) serves as Bulgaria’s main international gateway and typically functions as a full-service hub for flag and regional carriers while also accommodating low-cost airlines on many routes.

Travelers often find compact terminals with basic amenities and straightforward layouts, though peak times can feel crowded; its proximity to the city is a convenience, while occasional queues and limited late-night services can be drawbacks.
