ANR can shorten the arrival journey for northern Belgium. Reserve ahead and check the branch’s arrangements for your flight.
The airport lists rental desks in the main arrivals building, with Hertz and Sixt vehicle collection and return at P2. Confirm your own supplier and return bay before using that car park.
A car is useful for an Ardennes itinerary, rural guesthouses and stops outside the main railway network. For Brussels, Bruges, Ghent and Antwerp city breaks, compare rail with a rental: parking and city access can outweigh the convenience of keeping a car throughout the stay.
Compare airport collection with a later collection if you start with a city stay. Include the transport to a different rental branch and any extra parking nights when comparing the total cost.
