Skip the BRU rental desks and walk to a Cambio car
Cars sit in the P1 airport car park at Brussels Airport, so you just land in T, walk to P1, and pick up your Cambio Carsharing without talking to a counter agent. Cambio works well if you already have a Belgian membership and want to drive yourself into Brussels, Leuven, or another city and leave the car there instead of bringing it back to BRU. You pay by time and distance, not a fixed daily rental, which can be cheaper for a few focused errands or a short city stay.
Cambio at BRU uses the same booking system and app as in central Brussels, Ghent, and Antwerp, so you reserve the exact car in P1 before your flight lands. You unlock with your Cambio card or the app, then log the mileage and any damage in the onboard system in under 2 minutes. Refuelling is covered with a fuel card in the car; you only pay for your booked hours and kilometers, according to the Belgian tariff tied to your contract type.
You need a Belgian Cambio contract set up in advance, usually with a Belgian bank account and local address, so this is not a walk-up option like a classic rental with a passport and credit card. Cars at BRU tend to be small city models, typically 4–5 seats and compact luggage space, so 2–3 people with cabin bags fit far better than 4 adults with 4 hard suitcases. If you want a larger vehicle class, book that specific type in the app before you travel.
Trips can be one-way in the sense that you leave the car at its home station in town, so a BRU pickup and a return at a neighborhood station, for example in Ixelles or Schaerbeek, is normal as long as you respect the assigned station. You still must return the car to a Cambio location, not a random street, and late returns are charged per started 15 minutes. For runs into Brussels between roughly 07:00 and 10:00 or 16:00 and 19:00, factor in heavy ring-road and E40 traffic, which can easily double drive times compared with off-peak.
There is no staffed Cambio office at Brussels Airport, so support comes via the 24/7 phone number printed on the car key and in the app. If your flight into T lands after 23:00, double-check in the app that your booking window covers potential delays; Cambio charges from the start of your reservation, not from actual unlock time. One practical tip: before leaving P1, take a quick photo of the parking bay number and level so you can find the same spot fast when you bring the car back to the airport station.
