Quick answer: British Airways does not carry pets in the cabin, and does not accept them as checked baggage either. Only recognised assistance dogs travel in the cabin, at no charge. Every other animal — including a cat small enough to sit under a seat on a US domestic flight — travels as a cargo shipment, booked through the airline's cargo operation and in practice through an approved pet shipping agent. Emotional support animals do not qualify for the cabin. Call a travel expert at Fond Travels on +1 (323) 800 6001 and we will explain what your animal's journey actually involves.

Why there is no cabin option at all
American travellers find this the most surprising policy in international pet travel, because the US norm — a small dog in a bag under the seat — simply does not exist here.
- No pets in the cabin, at any size, on any route, including the airline's short-haul subsidiaries.
- No pets as checked baggage. There is no option to check an animal into the hold on your own flight.
- Recognised assistance dogs are accepted in the cabin at no charge, certified by an organisation belonging to one of the recognised international assistance-dog bodies.
- Emotional support animals are not accepted in the cabin and travel as ordinary pets, which here means cargo.
Part of the reason is the destination itself: the United Kingdom requires pets to enter as cargo, cleared by an approved handler at an authorised point of entry. That is a national import rule rather than an airline preference, which is why airlines flying into the UK cannot offer cabin travel into it even where they do elsewhere.
What cargo travel actually means
This is a different process from buying a ticket, and the sooner that is understood the better the trip goes.
- Booked through the cargo operation, not through passenger reservations, and usually arranged through an approved pet shipping agent.
- The agent does the work — crate specification, paperwork, delivery to the cargo terminal, and clearance and collection at the other end.
- The animal may not be on your flight. Cargo capacity is scheduled separately from passenger seats.
- The hold is temperature-controlled and pressurised, in the part of the aircraft used for live animals.
- An IATA-compliant crate is required — rigid, ventilated, secure, and large enough for the animal to stand, turn around and lie down naturally.
- Collection is at a cargo terminal, not at baggage reclaim, and often some distance from the passenger terminal. Plan the arrival day around that.
Dogs and cats are the common cases, but the cargo route accepts a far wider range of animals than any cabin policy would — birds, rabbits, ferrets and others, subject to the destination's rules.
What the United Kingdom requires
The UK's pet entry rules are the real timeline, and they are not flexible.
- An ISO-compliant microchip, implanted before the rabies vaccination. If the order is wrong, the vaccination has to be redone and the clock restarts.
- A rabies vaccination, with the waiting period after it observed before travel.
- An animal health certificate or the appropriate travel document for your country of origin, issued inside a short window.
- Tapeworm treatment for dogs, administered by a vet within a defined window before arrival and recorded. Missing this window is one of the commonest reasons an animal is held at the border.
- Entry through an authorised route and point of entry, with an approved handler.
Get the sequence wrong and the problem is not a fee — it is weeks of delay, or the animal being held on arrival at your cost.
