With a confirmed seat reservation, you have not purchased the right to a specific seat number (e.g. seat 4A). A seat reservation states a choice for a seat category such as an aisle or a window seat.
We reserve the right to change the seat allocation at any time, even after the boarding of the aircraft, for operational, security or safety reasons or for reasons of Force Majeure.
In this event, Brussels Airlines will do its utmost to provide you with a seat with the same features (window/aisle) and adjacent seating.
