Transporting your pet
When you want to transport your pet, you can rest assured that we will take the very best care of them. Pets must be booked to travel with British Airways World Cargo, and they will be carried in the aircraft hold.
Pet Travel Scheme
This scheme allows cats and dogs to travel between certain countries and certain UK airports without the need to go through the usual 6 months quarantine.

British Airways World Cargo has many years' experience in transporting live animals. Our personnel handle animal shipments everyday and pride themselves in taking as much care of them as you would yourself.
Most animals can be transported by air. The only limitation is the size of the cargo hold. Larger animals, such as horses and cattle, can be carried on one of our freighter services. However, on our passenger services, due to the size of the cargo hold, we carry smaller animals such as cats, dogs, birds, reptiles and tropical fish.
For more information on the transportation of large animals on our freighter network, contact your local
British Airways World Cargo office. Further information can also be found on the International Air Transport Association(IATA) website at
www.iata.org/whatwedo/live_animals and on the Department for Environment, Food and Rural Affairs (DEFRA) website at
www.defra.gov.uk/animalh/quarantine/index.htm.
The UK animal transporter authorisation (reference UK/REIGA/T2/00003654) permits British Airways to carry livestock.
