Brussels Airlines Baggage Allowance: Cabin Bags & Fees
Flying with Brussels Airlines? Check Economy Basic, Light, Comfort and Flex cabin baggage, checked baggage, liquid rules and fees before you travel.
Brussels Airlines' short-haul baggage allowance now varies significantly by fare. Economy Basic on selected European routes includes only a personal item, while other Economy fares include a standard 8kg cabin bag as well. The personal item can measure up to 40 × 30 × 15cm.
Cabin baggage is one of the first things to check before travelling with Brussels Airlines, because the number of pieces, permitted size and weight can differ by fare or travel class. The current allowance is summarised as follows: Economy Basic — short haul 1 personal item only 40 × 30 × 15cm Other Economy fares Personal item + 1 cabin bag 55 × 40 × 23cm / 8kg. Your smaller personal item, where permitted, should be suitable for stowage beneath the seat, while the main cabin bag must fit safely in the overhead locker.
Checked baggage with Brussels Airlines also depends on the ticket you have purchased rather than simply the destination. The current headline allowance is: Basic & Light: none included Comfort / Comfort Green / Flex: 1 × 23kg Business: 1 or 2 × 32kg by fare Max 158cm per piece. Lower-cost or light fares can exclude checked baggage altogether, while flexible and premium fares often provide a larger allowance. Always check the baggage entitlement attached to the individual booking before packing.
Size and weight are separate limits. A suitcase can be within the permitted dimensions but still be overweight, or it can be light enough while exceeding the airline's dimensional limit. Carry-on can be added to Economy Basic online Checked bags can be purchased Oversize / overweight fees apply. Additional, overweight or oversized baggage can therefore attract extra charges or different handling requirements.
Cabin baggage must also comply with airport-security and dangerous-goods rules, which are separate from Brussels Airlines's own baggage allowance. Liquids, gels, pastes and aerosols may be subject to the familiar 100ml container restrictions depending on the departure and connecting airports, while power banks and spare lithium batteries normally need to remain in cabin baggage rather than being packed in the hold.
This guide explains Brussels Airlines's cabin and personal-item rules, checked-baggage allowances, fare and travel-class differences, liquid restrictions, additional and excess baggage, and the practical points most likely to cause problems at the airport. If another airline operates part of your journey, check that carrier's rules as well because allowances can differ across a multi-airline itinerary.

Key Brussels Airlines Baggage Tips
On selected short- and medium-haul routes, Economy Basic includes only one personal item.
The Economy Basic personal item may measure up to 40 × 30 × 15cm and must fit beneath the seat.
Economy Light, Comfort, Comfort Green and Flex include the personal item plus 1 cabin bag.
Check the allowance on your Brussels Airlines booking before you pack. Fare, cabin and route differences can materially change what is included.
Measure bags externally, including wheels, handles and protruding pockets, rather than relying only on the manufacturer's stated suitcase size.
Weigh cabin and checked baggage at home. A bag can be within the size limit but still attract charges if it exceeds the permitted weight.
Keep the personal item genuinely small enough to fit beneath the seat if the airline requires under-seat stowage; do not treat it as a second full-size cabin bag.
If you already know you need extra checked baggage, add it before reaching the airport where the airline offers advance purchase; airport excess-baggage charges can be higher.
Where standard airport liquid rules apply, the container size matters: a partly used bottle larger than 100ml can still be rejected at security.
Pack full-size toiletries in checked baggage when appropriate, while keeping medication and anything needed during the journey accessible in the cabin.
Keep power banks and spare lithium batteries in cabin baggage, protected against short circuits, rather than placing them in the hold.

Checked baggage with Brussels Airlines: what you need to know
On short- and medium-haul services, Economy Basic and Economy Light do not include checked baggage. Economy Comfort, Comfort Green and Flex generally include 1 × 23kg.
Business Comfort and Comfort Green generally include 1 × 32kg, while Business Flex generally includes 2 × 32kg. Long-haul allowances vary by travel class and fare, with Economy Light also excluding checked baggage.
Each standard checked bag must remain within 158cm total linear dimensions, including pockets, wheels and handles. Extra baggage can be purchased, and overweight or oversized pieces may attract additional charges.
Brussels Airlines's checked-baggage entitlement can depend on the fare, travel class, route and the airline operating each sector. The allowance shown on your ticket or booking confirmation should therefore be treated as the final reference.
If your included allowance is not enough, additional baggage can usually be added where the airline offers this service. Arranging extra baggage before travel is generally preferable to discovering an excess at check-in.
A bag that exceeds the permitted weight, dimensions or number of pieces can be treated as excess, overweight or oversized baggage. Separate charges or handling restrictions may apply, and very heavy items may need to be repacked or carried as cargo.
For journeys involving another airline, do not assume the same checked-baggage rules apply throughout. Codeshare and interline itineraries can be governed by the operating carrier or the most-significant carrier under the applicable baggage rules.
Before travelling, check the baggage allowance attached to your specific Brussels Airlines booking, particularly if you have changed your ticket, upgraded your cabin or added a connecting flight.
Brussels Airlines cabin baggage rules: liquids, extras and restrictions
On selected European short- and medium-haul routes, Economy Basic includes only one personal item measuring up to 40 × 30 × 15cm. The standard 8kg cabin bag is not included with this fare.
Economy Light, Comfort, Comfort Green and Flex include one personal item plus one cabin bag measuring up to 55 × 40 × 23cm and weighing up to 8kg. Business Class includes the personal item plus two cabin bags, each with the same 8kg and dimensional limit.
Liquids and gels are limited to containers of no more than 100ml, packed into one clear resealable plastic bag of up to 1 litre. Partner-operated flights can apply the operating airline's cabin-baggage policy.
Cabin baggage must be small and light enough to be safely stowed in the overhead locker or, for a personal item, beneath the seat in front. Published measurements normally include wheels, handles and other protruding parts unless the airline explicitly states otherwise.
Typical products affected include toothpaste, deodorant, shampoo, conditioner, shower gel, sun cream, skincare and cosmetics. Medication, baby food and certain medical items can qualify for security exemptions when required for the journey, although supporting evidence may be requested.
Power banks and spare lithium batteries should be carried in cabin baggage rather than checked baggage and protected against short circuits. Other dangerous or restricted items can be prohibited entirely or limited to either cabin or checked baggage.
Brussels Airlines staff or airport handling agents may check cabin baggage at check-in or the gate. A bag that exceeds the permitted number, size or weight can be placed in the hold and additional charges may apply.
