Three Belgian airports, three routes
From the south of the province, Brussels Airport (Zaventem) is reached via the E411, across the plateau past Libramont and Namur to the Brussels Ring. It is the longest ride, but also the one with the widest choice of destinations.
For low-cost flights, Brussels South Charleroi Airport is the logical choice: the E411 or the N4 to Namur, then the E42 towards Gosselies. From the north of the region, around Bastogne, Marche-en-Famenne or Durbuy, Liège Airport at Bierset is often the closest, and the E25 or the N63 through the Condroz gets you there fastest. Eindhoven, Schiphol, Düsseldorf and Cologne Bonn are available too; the price table shows the fixed fare for each airport.
