Brussels Airlines — carry-on rules: size, weight and fares
Brussels Airlines: Light 55×40×23 cm, 8 kg; Basic 40×30×15 cm; Business 2×8 kg.
Economy Basic on selected European short/medium-haul routes includes only a 40×30×15 cm personal item. Economy Light, Comfort, Comfort Green and Flex include one 55×40×23 cm bag up to 8 kg, plus that personal item. Basic and Light are different fares.
Allowance
| Item | Limit |
|---|---|
| Main cabin bag | 55×40×23 cm, 8 kg |
| Personal item | 40×30×15 cm |
Business: two main bags up to 8 kg each, plus one personal item. Premium Economy on long-haul flights includes one 8 kg main bag. Long-haul Basic also includes a main bag; do not apply the European Basic restriction to every route.
On eligible Basic tickets, buy one main bag online or through the Service Centre no later than 2 hours before departure; this purchase is unavailable at the airport. HON Circle, Senator and Star Alliance Gold benefits can include one main bag. Confirm the benefit for your booking. Duty-free purchases count towards the allowance.
Before departure
Measure the fully packed bag, including protruding wheels, handles and pockets. Weigh it after packing. A stated size or weight limit is not a tolerance: 8.1 kg exceeds an 8 kg limit. Check every flight on a connection, including the operating carrier and booked allowance.
Family travel
A lap infant has no separate hand-baggage allowance; necessary baby food is allowed. One carrying basket, car seat OR folding stroller travels free in the hold. A cabin stroller counts within the cabin allowance. For a child with a seat, check the booked fare: the family page’s general 8 kg wording does not clearly resolve Basic.
Security and gate collection
A bag outside the allowance can be sent to the hold for €60–110 depending on the route, payable by credit card. This payment does not buy cabin access. A compliant bag can travel in the hold free on a full flight. Some aircraft and regional restrictions reduce Business to one main bag.
Ordinary liquids generally use containers up to 100 ml in one transparent resealable 1-litre bag. Necessary medicine, dietary products and baby food have screening exceptions. Check current departure and transfer airport instructions and keep sealed duty-free purchases with their receipt. Keep documents and essential medication accessible if staff collect your bag.
