Brussels Airport (BRU): The Complete Layover Guide

How BRU actually works

Everything hangs off one building. Check in upstairs, two piers out the back, the railway underneath. You can hold the entire airport in your head after one visit, which is exactly what you want at 6am.

Pier A handles the Schengen traffic, gates A40 to A72 plus the T gates that Brussels Airlines uses for its African network. Pier B is the non Schengen pier, departures on the upper deck and arrivals below, feeding straight into border control and baggage claim. The Connector building joins the piers to the check in halls, and the walk between the far ends of A and B runs 10 to 15 minutes. Each pier screens its own security, and the zones meet at passport control, not at another security belt.

Connections are this airport's quiet strength. The official minimum is 70 minutes, and unlike most published minimums it deserves some trust for Schengen to Schengen transfers, where there are no checks at all between arrival gate and departure gate. Crossing between piers adds border control, so give those itineraries 90 minutes or more. Arrivals from the US, Canada, UK, and Montenegro benefit from one stop security: no second screening, just the passport queue. Bags on a single booking transfer automatically; on separate tickets you do the full collect and recheck routine.

The lounge inventory is short and honest. The airport runs two: the Diamond Lounge up the escalator near gate A42, open 4:30am to 9pm, and The View between gates B04 and B05, open 5am to 10pm with a runway panorama that earns the name. Both take Priority Pass, which makes BRU unusually friendly to cardholders, since wherever you depart from, one of them is on your side of the border. Brussels Airlines closed The Loft in January 2026 for renovation, with reopening expected over summer 2026; in the meantime its Pop Up Loft near gate A27 and the Sunrise lounge at the end of Pier A cover business class and Star Alliance Gold, with no Priority Pass entry. Paid walk in entry to The View costs 39 euros at the desk, and the airport sells an online Lounge Pass through its own site.

Overnight is permitted and unremarkable. The terminal never fully closes, security tolerates sleepers with onward boarding passes, and the big couches in Pier A are the established real estate. The building runs cold and the announcements never stop, so pack accordingly. There are no sleep pods. The serious alternative is 39 steps from the terminal door: the Sheraton Brussels Airport, a 294 room property sitting directly above the railway station, close enough that a 5am departure barely requires an alarm clock buffer. A second on site hotel is planned as part of the airport's expansion program, but construction starts no earlier than 2027, so the Sheraton keeps its monopoly for now.

What the short lounge list leaves out, the terminal partly gives back. The seating around the duty free area near the Tintin rocket is decent for a wait, the couches in Pier A are better, and the building's compact scale means you are never far from food or a window with runway views. There are no shower facilities outside the lounges, so on a long haul to long haul connection The View's showers become the practical reason to use your Priority Pass rather than just the pleasant one. Walk in lounge passes are sold through the airport's own site, 39 euros at The View's desk, so check before assuming the door price beats your card.

Brussels itself is one of Europe's easiest layover cities to actually visit. Trains leave from level minus 1 every 15 to 30 minutes and reach Brussels Central in 18 minutes for about 11.20 euros second class, the airport supplement included on standard tickets bought at the machines in arrivals or online. The Grand Place is a 5 minute walk from Central. With 5 to 6 hours between flights the trip works comfortably for Schengen passengers; non Schengen travelers should add border control time on the way back in. With less than 4 hours, the View lounge and a Belgian beer airside is the better trade. One warning for bargain hunters: tickets sold as Brussels South are for Charleroi, a separate airport about 60 km away and roughly an hour by shuttle bus. Nobody connects between the two on purpose, and you should not be the first.
