British Airways Animal Policy: How Pets and Assistance Dogs Fly With BA in 2026

The British Airways animal policy is the set of rules British Airways (BA) applies to animals on its flights: pet dogs, cats and other animals travel only in the temperature-controlled aircraft hold as cargo, handled by BA's sister company IAG Cargo or its UK export partner PetAir UK, while recognised assistance dogs fly free of charge in the cabin. Emotional support dogs are not accepted in the cabin and must fly as pets. As of October 2026, pets entering Great Britain must also meet the UK Pet Travel Scheme rules.

This guide, written by the Animal Passport editorial team and last updated on 5 October 2026, pulls the policy together from British Airways, International Airlines Group Cargo (IAG Cargo), Heathrow Animal Reception Centre (HARC), Heathrow Airport, the Open Doors Organization (ODO) and the UK Department for Environment, Food and Rural Affairs (Defra). Airline and border rules change often, so check the linked official pages before you book.

British Airways animal policy at a glance

Can pets fly in the cabin on British Airways?

No. British Airways states on its 2026 assistance page that a dog that does not meet its assistance dog guidelines, or is an emotional support dog, "will need to travel as a domestic pet and cannot be in the cabin." Only recognised assistance dogs ride in the cabin.

IAG Cargo, which describes itself as the cargo handling arm of British Airways, Iberia, Aer Lingus, Vueling and LEVEL, says pets travel in the aircraft's hold, "in a temperature-controlled environment." IAG Cargo also says the hold is unlit because, in its experience, pets settle down and travel better in the dark.

How pets fly in the hold with IAG Cargo

IAG Cargo has carried pets since the 1950s, according to its pets page, and handles every consignment under the International Air Transport Association (IATA) Live Animals Regulations (LAR) and, for protected species, the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).

You usually cannot book a pet directly. IAG Cargo's Live Animals page (2026) says all live animal bookings, except pet bookings from North America and the Caribbean, must go through a freight forwarder with animal experience. It points owners to the International Pet and Animal Transport Association (IPATA) or the Animal Transport Association (ATA) to find a pet relocation agent.

Booking windows and check-in times

• Booking window: up to 14 days before scheduled departure, or up to 6 weeks for USA and Canada bookings (IAG Cargo, 2026).
• Check-in cut-off: live animals must be checked in 4 hours before departure, subject to station capability (IAG Cargo, 2026).
• Transit connections: minimum 240 minutes at London Heathrow (LHR) and London Gatwick (LGW), and 360 minutes at Madrid (MAD), according to IAG Cargo.
• Missed flights: IAG Cargo says it will notify you within 2 hours of actual departure if an animal does not fly as booked, and plans recovery to arrive within 24 hours of the original arrival time.

Breed and species restrictions

IAG Cargo says the "vast majority" of species are accepted on British Airways and Iberia, depending on aircraft size and capacity. It refuses animals for laboratory testing under any circumstances. It also warns that some dangerous dog breeds and snub-nosed (brachycephalic) cats and dogs may not be accepted, and asks owners to check through its enquiry form.

Separately, GOV.UK says you cannot bring a banned breed of dog into Great Britain unless it already has a valid Certificate of Exemption.

Travel container (crate) rules

IAG Cargo's 2026 container guidance follows IATA standards. Key points:

• Cats departing the USA and Canada need at least a 200-series kennel (68 x 50 x 48 cm internal); series 100 kennels are acceptable elsewhere.
• Snub-nosed dogs and cats need a container at least 10% larger than the minimum.
• The pet must be able to stand, sit upright and turn around without touching the top.
• Ventilation is required on all four sides, and the pet's nose and paws must not fit through any opening.
• A water pot must be fixed inside and fillable from outside.
• Fibreboard, wire mesh and wicker containers are not accepted.

Flying a pet out of the UK with PetAir UK

For pets departing the UK, IAG Cargo says it has partnered with PetAir UK to handle quotations and export bookings. PetAir UK describes itself as owned and run by vets and offers several commercial flight packages that cover collection, airport transport, veterinary arrangements and paperwork support. Prices are quoted per journey; British Airways does not publish a fixed pet fare.

Assistance dogs on British Airways

British Airways says it can carry an assistance dog free of charge in the cabin "on the majority of our flights." An assistance dog, in BA's words, "has been trained to provide support to a person with a visible or non-visible disability or medical condition."

Who counts as a recognised assistance dog

Heathrow Animal Reception Centre, run by the City of London Corporation, recognises dogs trained by a member of the International Guide Dog Federation (IGDF) or Assistance Dogs International (ADI), or accredited by The Assistance Dog Assessment Association. Dogs trained to the same or a higher standard may also be recognised if evidence is provided (HARC, updated March 2026).

Heathrow Airport adds that an assistance dog must be trained in specific tasks, behave appropriately in public and on board, wear an identifying jacket or harness, and stay under your control at all times.

How to register: the Open Doors Organization

British Airways asks passengers to register their dog before travel and recommends doing so before booking. The Open Doors Organization, a non-profit, lists British Airways among the airlines using its free Service Animal Forms portal. The process works like this:

1. Complete the web-based U.S. Department of Transportation (DOT) Service Animal Air Transportation Form on the ODO portal.
2. Receive a Service Animal ID Number. ODO may contact your trainer to verify training.
3. Once the form is accepted, book your BA flight and submit a Notification of Travel with your ID, booking reference, flight number and airports.
4. Wait for email confirmation that the dog has been added to the reservation.

ODO notes that airlines may require the DOT form 48 hours before travel, and Heathrow Airport advises telling your airline at least 48 hours before you fly.

Arriving at Heathrow with an assistance dog

Assistance dogs follow the same health rules as pets. GOV.UK says the Great Britain entry rules "also apply if you're travelling with your guide or assistance dog." To land at or transit through Heathrow, you need a pre-approval letter from HARC, and British Airways provides a PDF acceptance letter that HARC accepts as proof of airline acceptance.

The official timings do not match. Heathrow Airport says HARC approval must be in place at least 72 hours before your flight. HARC's own page asks for your Stage 1 email at least seven days before departure and says it aims to reply within 72 hours. Use the seven-day lead time to be safe.

HARC charges a £462 checking fee for an unrecognised service dog, and only issues pre-approval to unrecognised dogs arriving direct from the USA (HARC, 2026). On arrival, a HARC representative meets you at the aircraft door and the final checks take about five minutes.

Emotional support animals on British Airways

British Airways does not accept emotional support dogs in the cabin. They can still fly, but only as pets in the hold, booked through PetAir UK or IAG Cargo and charged as pets.

UK and EU paperwork for British Airways passengers

British Airways approves an animal to fly, but border authorities decide whether it can enter a country. If you are flying into Great Britain, GOV.UK (2026) sets out the Pet Travel Scheme steps for dogs, cats and ferrets:

1. Check your route is approved for pet travel.
2. Microchip your pet before its rabies vaccination.
3. Vaccinate against rabies, then wait at least 21 full days after the first vaccination.
4. Get the right pet travel document from your vet for the country you are leaving.
5. For dogs, get tapeworm treatment between 24 hours and 5 days before arrival in Great Britain.
6. Sign a declaration that you will not sell or transfer ownership of the pet.

GOV.UK warns that a pet that fails these rules can be put into quarantine for up to 4 months at the owner's expense. IAG Cargo also asks owners flying pets into the UK to sign a Form of Indemnity that covers British Airways against quarantine costs.

The April 2026 EU rule change

Defra and the Animal and Plant Health Agency (APHA) announced on 21 April 2026 that, from 22 April 2026, Great Britain residents should no longer use EU pet passports to enter the EU. Instead they need an Animal Health Certificate (AHC) for each trip. According to GOV.UK (2026), an AHC is valid for 10 days for entry into the EU, then for up to 6 months for onward travel within the EU and re-entry to Great Britain, as long as the rabies vaccination stays valid.

Defra also says a pet travelling with someone other than its owner must travel within five days of the owner, with written permission. GB residents can still use an EU pet passport for the return journey to Great Britain.

What pet arrivals cost at Heathrow

On top of the agent's airline quote, HARC lists its 2026 handling fees for pets arriving as cargo:

• £104 to collect the pet or pets from the aircraft.
• £213 boarding if your Pet Travel Scheme paperwork was pre-checked, or £293 if it was not.
• £55 for each additional pet.
• £99 administrative fee if HARC has to contact your vet to clarify paperwork, for example when only the vaccine manufacturer is written down and not the product name.

HARC says pets are ready to collect in 2 to 4 hours on average. Its page also lists IAG Cargo among the carriers whose pets are mostly not handled at the HARC facility, so confirm the collection point with your agent if your pet flies on British Airways. HARC says it handles about 22,000 dogs and cats arriving at Heathrow every year.

Step-by-step: planning a pet flight on British Airways

1. Decide whether your animal is a pet or a recognised assistance dog. That decides whether it flies in the hold or the cabin.
2. For a pet leaving the UK, request a quote from PetAir UK. For a pet flying from elsewhere, fill in the IAG Cargo pets form or contact an IPATA agent.
3. Check breed rules, especially for snub-nosed breeds and banned dog types.
4. Start the microchip, rabies vaccination and certificate process early. The 21-day rabies wait alone rules out last-minute trips.
5. Buy an IATA-compliant crate and get your pet used to it.
6. For an assistance dog, register with the Open Doors Organization, add the dog to your BA booking at least 48 hours ahead, and email HARC at least seven days before an arrival at Heathrow.
7. Book dog tapeworm treatment for 1 to 5 days before arrival in Great Britain.
8. Check in the pet 4 hours before departure, and carry original documents.

Where official sources disagree

British Airways' own wording varies by country site. Its Barbados-facing assistance page says assistance dogs fly free "on the majority of our flights", while its Germany-facing page says it can carry a certified service dog free "in the cabin of all our flights" but "might need to limit the number of dogs." The safe reading is that cabin space for assistance dogs is not guaranteed, so register early.

The HARC notice period is the other mismatch: 72 hours on Heathrow Airport's page versus seven days on HARC's page.

Airline pet documents vs Animal Passport's biometric livestock ID

Some readers search for "animal passport" when they mean airline pet paperwork, so it is worth being clear. The documents that matter for British Airways are government and veterinary documents: the microchip record, rabies vaccination certificate, Animal Health Certificate or Great Britain health certificate, EU pet passport where still valid, and HARC pre-approval for assistance dogs. Only these documents meet the UK Pet Travel Scheme and EU entry rules.

Animal Passport is a different product. It is a digital animal and livestock passport that identifies an animal by its muzzle print, which is unique to each animal like a fingerprint. A farmer captures the nose print on a phone, and the record links the owner, breed, estimated age, body condition and vaccination history. Age is estimated from a dental photograph with a confidence score, and body condition is scored 1 to 5 from a side-profile photo.

Animal Passport is not a government-issued travel document, does not replace a microchip or Animal Health Certificate, and is not accepted by British Airways or HARC as pet travel paperwork. Its main use is livestock identity. During livestock flood rescue in Pakistan in August 2025, farmers used it to reclaim animals after paper tags washed away. More livestock identity and animal travel guides are on the Animal Passport blog.
