Pet Travel
to London

Which Airport Should I Fly My Pet Into, and What Happens on Arrival?

London is served by two major airports capable of handling pet travel: Heathrow (LHR) and Gatwick (LGW). Heathrow is the more established option for live animal transport, with three live animal facilities on-site — the Heathrow Animal Reception Centre (HARC), the Animal Reception Centre (AAC), and the Airpets Animal Reception Centre — with your airline determining which one your pet is routed through on arrival. Gatwick also operates a dedicated Animal Reception Centre, though Heathrow handles significantly higher volume and offers more direct US routing.

Which airport makes sense for your pet often comes down to your airline and route. Direct flights into Heathrow are common from major US hubs, and pairing a direct flight with Heathrow's live animal facilities minimizes the number of transitions and handling points your pet experiences, which matters both for their comfort and their safety.

Once your pet lands, here's what happens: your pet clears through UK Border Force and DEFRA checks, where officials verify your pet's microchip, vaccination records, Animal Health Certificate, and (if applicable based on country of origin) titer test results against the physical animal. This is a documentation check, not a physical exam in most cases, and it moves quickly when your paperwork is in order. From there, your pet is released to ground transport, whether that's a pet-specific ground transport service, your own vehicle, or a service we coordinate directly. Having someone familiar with this exact handoff, who knows the facility and the process, is often the difference between a smooth arrival and a stressful one.

Which airports handle commercial pet shipments?

Heathrow and Gatwick are both approved for commercial (manifest cargo) pet shipments into London.

Important: the 48-hour residency rule. If your pet travels commercially into the UK, they must remain at the address listed on their Animal Health Certificate for 48 hours after being released from clearance before continuing to a different location. For example, if a pet flies into LHR but their final home is further north, and the certificate lists a hotel address near LHR, the pet must stay at that hotel for 48 hours before continuing north. The reverse also applies: if the certificate lists the client's final address and the pet clears at LHR, the owner has 8 hours to get the pet to that address, and the pet must then remain there for 48 hours. This isn't common, but a couple of recent cases make it worth planning around — we build this into your itinerary from the start.

What Airlines Fly Pets to London, and How Should I Choose a Route?

Several major airlines operate pet-friendly routes between the US and London, though their policies vary significantly in terms of size restrictions, cargo vs. in-cabin options, and seasonal embargoes. Per IATA Live Animals Regulations, airlines transporting live animals internationally must meet specific crate, handling, and documentation standards, which is part of why policies differ so much carrier to carrier.

Some airlines only accept pets as manifest cargo on these long-haul international routes due to size and safety regulations, while smaller pets may qualify for in-cabin travel depending on carrier weight limits and crate dimensions.

Choosing the right route isn't just about price. Direct flights significantly reduce the stress and risk associated with pet travel by eliminating layovers, which cut down on tarmac time, temperature exposure, and handling transitions. When a direct option isn't available, the choice of connecting airport matters just as much as the connection time, since not every airport has the infrastructure or staff trained for live animal transfers.

This is where a lot of pet owners get stuck: airline pet policies change frequently, vary by aircraft type, and often include restrictions that aren't obvious until you're deep into booking. Brachycephalic (flat-faced) breeds like French Bulldogs, for example, face additional restrictions or outright bans from many carriers due to respiratory risk. If your pet's route transits through the EU, for example due to breed restrictions, you'll need to be on the exact same flight as your pet to travel under a non-commercial certificate. Starwood manages this research for you, matching your pet's breed, size, and health profile against current airline policies to identify the safest, most direct route into London, then handles the booking and coordination directly with the airline's live animal cargo team.

Airlines also require their own documentation on top of the UK's entry requirements — this can include airline-specific forms (such as APHIS forms or American Airlines' own paperwork) and rabies certificates formatted to that carrier's exact specifications. We handle this airline-by-airline so nothing gets rejected at check-in over a formatting issue.

How Long Does the Process Take, and What Does It Cost?

Timeline is one of the most common questions we get, and it's worth planning around early since parts of this process can't be rushed. If you're relocating from a country that isn't on the UK's low-risk list, a rabies titer test is required, with a mandatory three-month waiting period after the blood draw — often the single biggest driver of the overall timeline for those relocations. Traveling from the US, this step isn't required, so your timeline is driven more by vaccination timing, the Animal Health Certificate's validity window, and flight availability. Add to that the time needed to schedule vet appointments, obtain the Animal Health Certificate within its 10-day validity window before travel, and coordinate flight booking, and most pet owners should plan for a process that starts at least four months before their intended travel date, if not earlier. See gov.uk requirements for full details.

Costs vary based on several factors: your pet's size and weight, whether they travel in-cabin or as cargo, crate requirements, the specific airline and route, and any additional services like ground transport on either end of the journey.

What we can say clearly is that starting early gives you more flexibility and typically lowers costs, since last-minute bookings on live animal cargo space are both harder to secure and more expensive. Working with a relocation specialist from the start also helps avoid costly mistakes, like a titer test (when required) that has to be redone because it wasn't submitted to an approved lab, or a missed tapeworm treatment window that delays your pet's entire trip.
