P4 sits roughly 10–15 minutes’ walk from Terminal T
P4 Long Term is the on-airport option you pick when the car stays for a week or more and you still want to stay within the Brussels Airport perimeter. It’s a surface lot, signposted as “P4 Long Term,” and you reach it via the standard airport access roads toward Terminal T. Walking time to the terminal usually runs about 10–15 minutes, depending on baggage and pace.
This is officially classed as long-stay parking, and prices scale down the longer you leave the car. Daily rates undercut the closer P1/P2 garages, especially once you pass the 3-day mark. You park your own vehicle, keep your keys, and use the pedestrian route or shuttle options when available to get to Terminal T’s departures level.
P4 Long Term is open 24/7, like the rest of the BRU parking estate, so late-night arrivals and early-morning departures around 05:00–07:00 are fine. Entry and exit use ticket or plate recognition at the barrier. Pre-booking online through Brussels Airport generally locks in a lower price versus drive-up, and you’ll see “P4 Long Term” explicitly listed in the booking flow.
Security is standard for an on-airport lot: fenced perimeter, controlled entry, and lighting across the rows at night. Unlike some off-site fields 3–5 km away, you are still inside the official Brussels Airport site, which many people prefer when leaving the car for 7–14 days. Height limits are a non-issue here because this isn’t a multi-storey structure.
Tip: check the airport’s parking map before you drive in, then follow the P4 signs as soon as you reach the main BRU access road; missing the turn can add a 5–10 minute loop back to Terminal T and the parking entrance.
