The most efficient way to get from Brussels Airport (BRU) to the city center in 2026 is by train, which departs every 10–15 minutes from the station located directly under the Arrivals hall. The journey to Brussels Central Station takes about 17 to 20 minutes and costs approximately €10.80 (including the "Diabolo" airport supplement). For budget-conscious travelers, the STIB Airport Line (Bus 12) offers a cheaper alternative at roughly €7, taking about 30–40 minutes to reach the European Quarter. Taxis and private transfers are also readily available 24/7 at the airport exit, costing between €45 and €55 and taking about 20–30 minutes depending on traffic.
