TAP Air Portugal and Cats: Cabin Rules, the Gatwick Restriction, and What the Return Leg Actually Means

TAP Air Portugal allows cats in the cabin on eligible routes, including some flights departing from the UK — making it a practical option for UK travellers flying out to Portugal or onward into southern Europe with their cat in the cabin. The weight limit is 8 kg including the carrier, the fee starts from €70 for European routes, and you need to book at least 24 hours before your flight.

But two things catch UK travellers out, and neither is obvious from the headline policy. First: the airport you’re departing from matters — TAP explicitly excludes cabin and hold pet transport from London Gatwick. Second: the return journey is a different situation entirely. Here’s what you need to know before you book.

Does TAP Air Portugal allow cats in the cabin?

Yes — with conditions. TAP allows cats (and small dogs) to travel in the cabin on most routes if they are at least 10 weeks old and their combined weight with the carrier does not exceed 8 kg. The carrier must have a flexible structure, close securely, and fit under the seat in front of you. The maximum carrier dimensions are 45 × 30 × 23 cm (length × width × height).

One carrier is permitted per passenger, and the carrier can contain up to two animals of the same species. Your cat must remain fully inside the carrier for the entire flight — head and tail included — and the carrier must be watertight.

The fee for European routes (including UK departures to Lisbon or Porto) is from €70 if booked online in low season, or from €80 in high season. Booking at the airport or through a travel agency costs slightly more. You need to add the pet service at least 24 hours before departure.

(Fees for European routes, verified from flytap.com, May 2026. TAP notes prices may vary by channel, route, and timing — confirm the current fee at booking.)

TAP reserves the right to refuse cabin transport if the conditions above are not met, and may transfer your cat to the hold at the gate. Cabin pet spaces are limited and allocated separately from seats — availability is not guaranteed on every flight, even when seats are available.

The UK departure restriction — which airports TAP accepts cabin pets from

This is the detail most articles miss entirely.

“In flights departing from London Gatwick Airport (LGW), the carriage of pets as baggage, either in the cabin or in the aircraft’s hold, is not permitted.” — TAP Air Portugal pet policy, flytap.com

That means if you’re flying from Gatwick, there is no option for your cat to travel on the same TAP flight — cabin or hold. It is a blanket exclusion for that departure point.

From London Heathrow (LHR), TAP operates routes to Lisbon and Porto where cabin pet transport is available, subject to the standard conditions above. For Manchester or any other UK departure point shown in TAP’s booking system, check the specific TAP-operated route and pet acceptance directly with TAP before purchasing — airport-level restrictions can apply and policies can change without notice.

Northern Ireland is also treated separately in TAP’s documentation requirements, so if you’re departing from Belfast, check the current position with TAP directly.

The practical upshot: if your instinct is to fly from Gatwick because it’s convenient, you will need to either switch to a Heathrow departure or find an alternative airline entirely. Do not assume the headline policy covers every UK airport — it does not.

The return leg — why your cat can’t fly back the same way

If you’re travelling from the UK to Portugal (or elsewhere in Europe) and planning to return, the homeward journey is a separate problem — and not one TAP can solve in the cabin.

“Flights to the United Kingdom: Pets cannot be transported in the cabin or the aircraft’s hold (on direct routes or with stopovers), except for assistance pets, which are permitted in the cabin.” — TAP Air Portugal pet policy, flytap.com

This is not a TAP quirk. It reflects the UK government rule that sits behind it: pets travelling to Great Britain by air must travel as cargo — the only exceptions are chartered private aircraft and guide or assistance dogs travelling with their owners. GOV.UK states this directly. No cabin-pet option exists on any airline for inbound UK flights under this rule.

What this means in practice: your outbound journey from Heathrow to Lisbon can be in the cabin. Your return from Lisbon to Heathrow must be arranged separately as air cargo, using an approved pet travel route and the relevant cargo handling arrangements for that airport. These are different logistics, different paperwork, and different costs — and they require advance planning.

If you’re at the research stage for a round trip, factor the return leg into your planning before you book anything. Our full UK-to-EU cat travel guide covers the documentation requirements and the key timing risks for both directions.

What the booking process looks like

Once you’ve confirmed TAP flies your specific route and that your departure airport is not Gatwick, the booking process is straightforward — but the timing matters.

TAP requires the cabin pet service to be requested at least 24 hours before the flight. In practice, the earlier the better: cabin pet spaces are limited and are allocated separately from seat availability. A flight showing as fully available does not mean a pet space is available. The safest approach is to add your cat when you first book the flight, not as an afterthought.

You can book the pet service online through TAP’s website during the booking flow, or request it later through TAP’s contact centre (at a slightly higher fee). Do not arrive at the airport expecting to add a cat at check-in — there is no guarantee of space, and you may be refused.

Once you’ve confirmed TAP flies your route from the right airport, booking early is the single most useful thing you can do. Search TAP Air Portugal flights →

What your cat needs for a UK→Portugal flight

The documentation requirements are determined by your destination, not your airline. Flying TAP does not change what Portugal (as an EU member state) requires.

TAP’s own policy page sets out the requirements for flights departing the UK (excluding Northern Ireland and Gatwick):

• Microchip — enabling your cat’s identification
• Valid anti-rabies vaccination — must be administered when the microchip is implanted or afterwards, and at least 21 days before your travel date
• Health Certificate (AHC) — issued by a veterinarian officially recognised by the Department for Environment, Food & Rural Affairs (Defra), or the Scottish or Welsh governments. Valid for 10 days after the date of issue.

That last point is the one that catches people out. The AHC is valid for only 10 days — which means it must be issued close to your departure, not weeks in advance. But your vet needs notice to issue it, and some practices have limited availability. Book your AHC appointment before you finalise your travel dates, not after. If your cat has had a first rabies vaccination for this trip, the 21-day wait must have elapsed before the AHC can be used.

Switching to TAP does not change these requirements. They apply on any airline flying your cat from the UK to an EU destination.

Frequently asked questions

Does TAP Air Portugal allow cats in the cabin?
Yes. TAP allows cats in the cabin on most routes, including from the UK, subject to a combined weight limit of 8 kg (cat plus carrier), a maximum carrier size of 45 × 30 × 23 cm, and a booking request at least 24 hours before departure. Cabin pet spaces are limited. (Policy verified from flytap.com, May 2026.)

Which UK airports can I fly from with my cat in the cabin on TAP?
Not Gatwick. TAP explicitly states that pet transport — in the cabin or hold — is not permitted on flights departing from London Gatwick Airport (LGW). From London Heathrow (LHR), cabin pet transport is available on TAP routes to Lisbon and Porto. Confirm your specific departure airport with TAP before purchasing, as restrictions can apply and policies can change.

What is TAP’s cabin pet fee for a UK–Europe flight?
From €70 online in low season, from €80 in high season. Booking through TAP’s contact centre or at the airport costs slightly more. Fees are per pet service, not per animal. Confirm the current fee when booking — prices can change without notice. (Verified from flytap.com, May 2026.)

What carrier dimensions does TAP require for cabin pets?
The maximum carrier size is 45 × 30 × 23 cm (length × width × height). The carrier must have a flexible structure, close securely, and fit under the seat in front of you. Measure your carrier before flying — a carrier that exceeds TAP’s dimensions may be refused at the gate.

Can I bring my cat back to the UK on TAP in the cabin?
No. TAP’s policy states that pets cannot be transported in the cabin or hold on flights to the United Kingdom, with the exception of assistance pets. This reflects the UK government rule: pets travelling to Great Britain by air must travel as cargo — the only exceptions are chartered private aircraft and guide or assistance dogs. The return leg requires a separate cargo arrangement via an approved route and handler; it cannot be done in the cabin on any airline.

How do I add my cat to a TAP booking — at booking or afterwards?
TAP allows you to add the pet service online at the time of booking (cheapest option) or afterwards through their contact centre (slightly higher fee). The service must be requested at least 24 hours before departure, and cabin pet spaces are limited. Adding your cat at the time of booking is strongly recommended.

What documents does my cat need for a UK→Portugal flight?
A microchip, a valid anti-rabies vaccination (administered on the same day as the microchip or afterwards, and at least 21 days before travel), and a Health Certificate (AHC) issued by a Defra-recognised vet. The AHC is valid for only 10 days after issue, so it must be timed carefully relative to your departure date. These requirements apply regardless of which airline you fly — they are EU entry requirements, not TAP-specific rules.

Does TAP allow cabin pets on connecting flights through Lisbon to other destinations?
TAP’s pet policy covers flights operated by TAP — if your trip includes a connection with another airline, you need to verify the connecting carrier’s policy separately. TAP also notes that pet transport is not available on GOL and Azul codeshare flights. Confirm your full itinerary with TAP before booking if your journey involves any connections.

TAP is one of the more practical options for a UK reader wanting to fly to Portugal or southern Europe with their cat in the cabin. The policy is clear, the fee is reasonable, and Heathrow departures are well served. The two things that derail people — the Gatwick exclusion and the return-leg cargo requirement — are both avoidable with early planning. Confirm your departure airport, book the pet service at the time of booking, and sort the AHC timeline before you finalise your travel dates.
