Know how your dog will travel

Checked pet in the holdYour dog is accepted with your passenger booking, generally on the same flight, and travels in an approved kennel.
Air cargoYour dog is booked through a cargo operation, with separate paperwork, drop-off and collection; the flight may differ from yours.
Always confirm before booking. Policies depend on aircraft, operating carrier, destination, breed, temperature, pet age and availability. The figures below are published guidelines, not guaranteed acceptance. Service dogs are governed by separate rules.
