I'd like to purchase additional services but I can't do it. What should I do?
The availability of additional services depends on the flight's operating carrier: extra baggage and seat reservations are not available online on codeshare flights. You will need to add them at the airport.
Insurances are the only additional services available online when booking a codeshare flight. However, some insurance policies may not be available for your trip (e.g. no travel insurance for one-way tickets).
Seat reservations are only available on connecting flights when operated by Brussels Airlines.
