Flying Brussels Airlines With Your Dog: Cabin, Hold, Fees and How to Book

Brussels Airlines takes small dogs in the cabin and bigger dogs in the hold, within Europe and on its flights to Africa and North America. Here's the short version, checked September 2026. Rules change, so confirm on Brussels Airlines' pet page before you fly.

In the cabin: up to 8 kg, dog and bag together

  • Weight: max 8 kg for dog + bag together.
  • Bag: max 55 × 40 × 23 cm. It goes under the seat in front of you.
  • Where you sit: a window seat, not in an exit row or at the bulkhead.
  • How many: max 4 pet bags in the cabin per plane. Minimum age 15 weeks.

In the hold: kennels up to 125 × 75 × 85 cm

Too big for the cabin? Your dog flies in the hold, the heated luggage space under the floor of your own plane, in a hard IATA kennel. See what a hold kennel must have.

  • Kennel: max 125 × 75 × 85 cm. The price depends on the size: medium up to 60 × 45 × 40 cm, or large.
  • Transfers: changing planes in Brussels, Frankfurt, Zurich, Vienna or Geneva costs an extra €150 per direction.
  • Booking: a dog in the hold can only be booked through the Brussels Airlines Service Centre.

What it costs

How to book your dog's spot

  1. Book your own ticket first, then add your dog straight away. With only 4 pet bags allowed in the cabin, spots go fast.
  2. Hold: call the Service Centre to book the kennel.
  3. Cabin: pick a window seat.
  4. Bring the EU pet passport, a microchip and a rabies shot at least 21 days old.
