British Airways Pet Policy: No Cabin Pets, and What That Means

British Airways is the airline people ask about most for a move to the UK, and it is also the airline with the shortest answer to the first question. BA does not carry pets in the cabin. Not on transatlantic routes, not on short hops, not for a small cat in a soft bag. The airline’s own wording is “we don’t carry pets in the cabin on any route.”

That single sentence changes the shape of the whole trip. It means a pet flying BA travels as manifest cargo, booked through an agent rather than added to your own reservation, and it means the UK arrival process applies with its own handling and its own charges. This guide covers how that works, what the crate has to be, what the UK requires before you fly, and what it costs on landing. Everything here is from British Airways, IAG Cargo, the City of London and GOV.UK, checked on 8 September 2026.

Most US carriers let a small dog or cat travel under the seat for a fee. British Airways does not, and there is no size, weight or fare class that changes it. If you have been pricing a cabin booking on BA because the pet is small, that option does not exist.

This is worth knowing early, because it is usually the difference between a simple trip and a managed one. A cabin pet is a booking and a carrier bag. A cargo pet is an IATA crate, an agent, a customs entry and an animal reception facility on the other end. The cost gap between the two is large, and so is the lead time.

British Airways carries recognized assistance dogs in the cabin free of charge on the majority of its flights. That is a separate category from pet travel and has its own documentation and advance notice.

Emotional support dogs are not included. BA states they cannot travel in the cabin and are treated as pets, which puts them back into the cargo process described below. This distinction catches people out on US to UK routes in particular, because some US carriers historically treated the two categories more loosely on domestic flights.

Pets travel in the temperature-controlled hold, handled by IAG Cargo, which is the cargo arm of British Airways, Iberia, Aer Lingus, Vueling and LEVEL. For pets leaving the UK, BA points people to PetAir UK. For pets coming into the UK, IAG Cargo handles the arrangements.

You do not book this yourself the way you book a seat. IAG Cargo works through pet travel agents, and its own guidance is to contact one, who then makes the cargo booking, prepares the paperwork and handles the airport side at both ends. That is not an upsell on their part. Manifest cargo requires an export entry, an import entry and a physical handover at a cargo terminal, and none of those are things a passenger can do at a check-in desk.

IAG Cargo also says that some dangerous dog breeds and some snub-nosed breeds of cats and dogs may not be accepted, and that the agent will advise on a specific animal. So breed clearance is a question to settle before you fix a date, not after. Our list of banned dog breeds by country covers the destination side of the same question.

IAG Cargo works to the IATA Live Animals Regulations, and it publishes one requirement that matters specifically to Americans. Series 100 kennels are acceptable for most countries. For departures from the USA and Canada, a Series 200 kennel is required.

Series 100 is the ordinary two-piece plastic travel kennel sold in every pet store. Series 200 is a heavier specification with a stronger frame and different fastening. If you buy the crate first and check the requirement second, this is where the money goes twice. Buy for the route, not for the aisle in the store.

The general container rules are the ones the IATA regulations set out. The crate must be strong enough to protect the animal, secure enough to contain it, and have ventilation on all four sides. The door has to be secured so that it cannot open accidentally. Fiberboard, wire mesh and wicker containers are not acceptable for air transport at all. Our guide to airline crate requirements goes through the full specification, and the crate size formula covers measuring the animal.

Where IAG Cargo does accept a snub-nosed dog or cat, its stated minimum is a container 10 percent larger than the normal minimum for that animal.

That is a real planning number rather than a formality. Ten percent on each dimension moves a borderline animal up a kennel size, which moves the chargeable volumetric weight, which moves the freight quote. For a flat-faced breed, size the crate before you take a price seriously, because a quote built on the smaller kennel will not survive the booking.

The entry rules are set by the UK government, not the airline, and they are the same whichever carrier you use. For a dog, cat or ferret coming from the United States into Great Britain:

The USA sits on the UK’s listed countries table, which is the reason a rabies antibody blood test is not part of that sequence. GOV.UK applies the blood test requirement to pets traveling from countries that are not listed. That one classification is worth several months of lead time, since the titer route elsewhere carries a waiting period measured in months rather than days. Our explainer on whether you need a pet passport covers how the documents differ by destination.

Extra rules apply if you are bringing more than five pets and are not attending or training for a competition, show or sporting event. Above that number the movement stops being treated as non-commercial, which changes the paperwork and who checks it on arrival.

This is the part almost nobody prices in advance. Pets arriving at Heathrow as manifest cargo go to the Heathrow Animal Reception Centre, run by the City of London. Staff collect the animal from the aircraft in a climate-controlled vehicle and take it to the facility, where the Pet Travel Scheme paperwork is checked before customs clearance can be arranged. Non-commercial movements are checked by Animal Reception Centre staff and commercial ones by APHA.

The Animal Reception Centre publishes its charges, which are separate from anything the airline or the agent charges:

The £80 gap between the two boarding rates is the clearest argument for the pre-check there is, and it is something to ask an agent about by name rather than assume is included. The Animal Reception Centre says pets are ready to collect within 2 to 4 hours from arrival on average.

These figures were published at the time of writing and the Animal Reception Centre does not state a VAT position or an effective date alongside them, so treat them as the current published rates rather than a locked quote, and confirm at booking. They will normally appear inside an agent’s total rather than as a separate line, which is exactly why they are worth asking about.

A pet move to the UK on British Airways has four moving parts, and they run on different clocks. The rabies sequence sets the earliest possible travel date, at 21 days after vaccination and only after the microchip. The crate has to be a Series 200 out of the US, and 10 percent larger again if the animal is snub-nosed. The booking is a cargo booking made through an agent, not a seat. And the arrival has its own handling and its own published charges at the Animal Reception Centre.

None of it is difficult in isolation. What makes UK moves go wrong is doing them in the wrong order, most often buying the crate before checking the series, or fixing a date before confirming the breed will be accepted. If the UK is where you are heading, our USA to United Kingdom cost page breaks down the freight and paperwork side, and the United Kingdom destination guide covers the requirements in full.

No. British Airways does not carry pets in the cabin on any route, and there is no exception for small animals. Cats travel in the hold as cargo, booked through a pet travel agent.

No. The pet flies as manifest cargo with IAG Cargo, which is a separate booking from your ticket and is made through a pet travel agent. The animal can be on the same flight as you, but it is not attached to your reservation.

A Series 200 kennel. IAG Cargo accepts Series 100 for most countries but requires Series 200 for departures from the USA and Canada. Add 10 percent to the minimum size if the animal is snub-nosed.

GOV.UK applies the rabies antibody blood test to pets traveling from countries that are not on its listed countries table. The USA is on that table, and the document required from the US is a Great Britain pet health certificate.

The Heathrow Animal Reception Centre says pets are ready to collect within 2 to 4 hours from arrival on average. The paperwork check has to clear before customs clearance can be arranged, which is why a paperwork pre-check is worth asking your agent about.

Not on British Airways. BA carries recognized assistance dogs in the cabin on most flights, but states that emotional support dogs cannot travel in the cabin and are treated as pets, which means the cargo process.

Lufthansa does carry small pets in the cabin, which makes it a genuine alternative for a small animal heading to Europe. Its hold rules are stricter in other ways, and our Lufthansa pet policy guide sets those out.
