Brussels is served primarily by Brussels Airport (BRU) in Zaventem, the country’s main international hub handling most long-haul and network carriers, and by Brussels South Charleroi (CRL), a budget-oriented airport popular with low-cost airlines. BRU sits about 12 km northeast of the city centre and is usually reachable by train in roughly 20–30 minutes (modest fares), or by taxi in 20–40 minutes depending on traffic. Charleroi lies around 46 km to the south and typically involves a 50–70 minute coach transfer or a longer taxi ride, with shuttle fares often seen as the cheaper option. BRU tends to offer more full-service amenities and frequent connections, while Charleroi can be more cost-effective but less centrally located and with fewer on-site services—good to weigh convenience versus price when choosing.

Bucharest is served primarily by Henri Coandă International (OTP), the main international gateway and hub for full-service and many low-cost carriers; it handles most long-haul and connecting flights and can be busier and pricier than smaller fields. OTP lies about 16–20 km north of the city center and is reachable by express train or bus in roughly 25–45 minutes (fares are typically low to moderate), while taxis or rideshares take 30–45 minutes depending on traffic and can cost more. Pros: broad airline choice, decent transfer options and services. Cons: occasional congestion and varying transfer times at peak hours. Aurel Vlaicu International (Băneasa, BBU) historically served domestic and short regional hops and can be positioned as a closer, budget-friendly option for select low-cost and charter operators. Located approximately 8 km from central Bucharest, it offers quick taxi or tram links of about 15–25 minutes with modest fares, though scheduled public connections can be limited. Pros: proximity to the city and faster transfers for nearby routes. Cons: fewer airlines, reduced long-haul options and limited facilities compared with the main international airport.
