Flying to Great Britain with a pet: why not in the cabin, and the way in through the EU

By plane, a pet arrives as cargo

Great Britain’s guidance for bringing in a dog or a cat has one rule about planes:

Outside those two cases, a pet on a plane is cargo. The flight has to be an approved one, and so does every other way in:

The approval comes as two lists, one for air and one for sea and rail.

The cargo rule is written for planes. The second list is the other way in: fly to the EU, then cross by sea or rail. The rest of this article follows that route.

The same limit on the airlines’ own pages

Airlines state the limit from their side. Of the carriers entry.pet covers, these name the United Kingdom on their pet pages. With each is what it accepts in the cabin elsewhere.

In this table an airline that carries a dog or a cat in the cabin elsewhere does not carry it that way to Great Britain. Choosing another carrier does not change this, because the limit is Great Britain’s.

The first border: an EU airport

A flight into France or the Netherlands is an entry into the EU, under the EU’s rules. The European Commission says where a pet from outside the EU may come in:

Each Member State publishes its own list, and the Commission’s page links them. The Dutch list includes Amsterdam’s airport (AMS). Check your airport before you book.

What the pet needs there depends on the country it comes from. From a listed country where the owner lives, such as the United States, the document is an EU animal health certificate with a short life:

From a country the EU does not list, such as Thailand, a rabies antibody titer test comes first, and the blood sample has to be collected

Our article on the EU’s 2026 pet travel law explains how those days are counted.

Whether the pet may ride in the cabin on this flight is for the airline to say. The table of airlines above shows which of them publish cabin limits for dogs and cats.

The crossing: a route on the approved list

The crossing itself has to be one of the approved sea and rail routes. One of the rail entries reads:

The version of the list quoted here is dated 22 September 2026. Look your route up on the agency’s page close to the day you travel, and read what the list of sea and rail routes above says about Eurostar.

The check can come before the ship or the train leaves:

For travel by sea the guidance names a second outcome when the rules are not met:

So on this route the documents have to be complete before the port.

The second border: the documents Great Britain accepts

Great Britain sorts its paperwork by the country the pet is travelling from. On this route that is an EU country, and the guidance lists what it accepts:

That is a pet passport, an animal health certificate issued in Great Britain, a Great Britain pet health certificate, or an older British passport. The EU certificate the pet flew in on is not among them. For a passport issued in the EU, the European Commission says whom it is for:

An owner who lives outside the EU, with a pet that holds no British document, is left with the Great Britain pet health certificate. Its own page confirms that it can be used from an EU country, which Great Britain counts as a Part 1 listed country:

The guidance also sets who signs it and how long it lasts:

So this route has two certificates and two clocks. Great Britain’s 10 days run from the day its certificate is issued to the day the pet enters Great Britain. The EU’s limit, quoted above, runs to the day the pet enters the Union.

A dog has one more deadline:

The window counts back from the arrival in Great Britain, not from the first flight. The step is on our checklists for a dog crossing from the Netherlands and from France. A cat’s checklist has no such step.

The rabies blood test and the country you travel from

Great Britain asks for a rabies blood test in one case:

On that wording, a pet crossing from France or the Netherlands is travelling from an EU country. The test has not left the journey: a pet that set out from a country the EU does not list needed the EU’s titer test, and its wait, to land at the EU airport.

So the route through the EU changes how the pet flies, not how long the preparation takes. For an adult pet starting from nothing, our checklists put Thailand to Great Britain at about 18 weeks and Thailand to the Netherlands at about 18 weeks; the United States to Great Britain at about 4 weeks and the United States to France at about 4 weeks.

If your pet set out from a country that is not listed, ask the Animal and Plant Health Agency before you book how it will read a journey in two legs.

Before you book

• Read the two legs as two checklists: the United States to France with a dog, then France to Great Britain; or Thailand to the Netherlands with a cat, then the Netherlands to Great Britain. Change the countries to your own.
• Count the EU certificate back from the day you land. Count the British certificate and, for a dog, the tapeworm treatment back from the day of the crossing. Check a crossing date for a dog from France.
• The full requirements are in the Great Britain guide, with the guides to France and the Netherlands for the first leg.

Whatever the route, confirm with the Animal and Plant Health Agency, with the veterinary authority of the Member State you land in, and with your airline and the ferry or tunnel operator before you travel.
