What Makes An Airlines Pet-Friendly?

Before diving into the list of airlines that allow pets in-cabin on international flights, it’s important to understand what actually makes an airline pet-friendly. It’s not just about letting your pet on board - it’s about how comfortable and safe they can travel.

A pet-friendly airline is one that:

Allows pets in the cabin instead of restricting them only to cargo.
Has clear and transparent policies on pet size, carrier dimensions, and health documentation.
Provides reasonable fees for in-cabin travel and limits the number of pets per flight to ensure comfort.
Offers trained staff who understand how to handle pets during security checks and boarding.
Maintains climate-controlled cabins and holds if pets must travel as checked baggage.

The best airline for pets combines flexibility with safety, which ensures your pet is secure without unnecessary stress.

Best Pet-Friendly Airlines For International Flights

Here’s a look at some of the most pet-friendly airlines that allow pets in-cabin on international routes, along with their basic policies and insights that travellers find useful.

1. KLM Royal Dutch Airlines

KLM is one of the most accommodating international carriers when it comes to pet travel. Small cats and dogs can travel in-cabin on most international flights as long as the combined weight ( pet + carrier) does not exceed 8kg. The soft-sided carrier dimensions must not exceed 46 x 28 x 24 cm. The carrier must fit under the seat in front of you. KLM also allows pets in the hold for larger breeds and has excellent transit facilities at Amsterdam Airport, where pets can be walked, fed, and checked by staff. KLM accepts pets in both Economy and Business Class except on long-haul business flights where seat configuration does not allow under-seat storage.

Tip: Always add your pet to your booking at least 48 hours before departure, as KLM limits the number of pets per flight.

2. Air France

Air France is another excellent choice for travelers flying internationally with pets. Cats and small dogs are welcome in-cabin on most international flights if they weigh under 8 kg, including the carrier, which must fit under the seat, max size 46 x 28 x 24 cm. The pet carrier must be soft-sided, ventilated, and fit under the seat. Only 1 pet is allowed per passenger, and the pet must be at least 15 weeks old. Air France has specific check-in counters and a dedicated “La Premiere” pet care process at major airports, ensuring a smooth experience. The airline's digital portal allows you to check specific restrictions for your destination - for instance, pets are not allowed in-cabin on flights to the UK or Ireland according to government regulations.

3. Lufthansa

Lufthansa’s “Animal Lounge” in Frankfurt is proof of how seriously the airline takes animal travel. Small cats and dogs up to 8kg, including carriers, can travel in the cabin on most international routes. Your pet must travel in a leak-proof soft-sided bag no larger than 55 x 40 x 23 cm placed under the seat in front of you. The airline allows two pets per passenger ( one in-cabin and one as checked baggage) and requires prior registration at least 72 hours before departure. Lufthansa’s in-transit facilities are some of the best in Europe, making long layovers easier for pet travelers. Frankfurt hub features a world-class Animal Lounge, which is a 43,000 sq ft. space with veterinarians and pet care staff available 24/7. This makes sure that you can travel easily with your furry best friend.

4. Air Canada

Air Canada is one of North America’s most pet-friendly carriers. Small cats and dogs can travel in-cabin on select international flights, provided the carrier fits under the seat and the pet’s weight meets the airline’s limit, typically under 10 kg combined. The carrier dimensions must not exceed 23 x 40 x 55 cm for hard-sided or 27 x 40 x 55 cm for soft-sided carriers. Your pet must remain inside the carrier for the entire flight.

Air Canada limits the number of pets per cabin to 2 in Economy & 1 in Business class, so it’s important to reserve early.

Pets are not accepted in-cabin for flights to/from Hawaii, Barbados, Jamaica, and the UK due to destination laws.

5. United Airlines

United Airlines allows cats and small dogs to travel in-cabin on most international routes, provided they can fit comfortably in an approved carrier under the seat in front of you. The combined weight limit is not specified, but the pet must have enough space to stand and turn around. Carrier dimensions vary slightly by aircraft but generally should not exceed 44 x 30 x 19 cm. Only one pet per passenger is allowed in the cabin, and a reservation is mandatory. United’s PetSafe Program and its in-cabin care team are widely recognised for handling animals with care.

Countries like the UK, Australia, and Japan have strict quarantine and rabies entry requirements, so check destination rules before traveling.
