Brussels Airlines carries dogs and cats in the cabin up to 8 kg and in the hold. The service is paid: 60 EUR per flight. The pet's place is booked in advance — at least 48 h before departure.

Snub-nosed breeds are not accepted in the hold. A heat limit applies: above 29.4 °C animals are not accepted in the hold. Direct flights reach 44 countries, but flying there and taking a pet are different questions: the destination country has its own entry rules.
