If you plan a journey with your pet, you should register it while booking your own seat. If you have already booked a flight, you can do it by calling the Customer Service Center at +32 (0)2 717 86 81. The number of animals per flight is limited, so registration and confirmation at the Service Center are required in any case. If you do not inform the company of your intention to bring a pet in advance, you may be charged an additional €7.5 at the airport or even not be allowed to transport your pet.
