Cabin vs cargo: can your pet fly in the cabin?

Prepared by the Animals Productions editorial team. See about us and our editorial standards.

Most small dogs and cats can fly in the cabin if the pet plus carrier stays under the airline's weight limit — commonly around 8 kg — and the carrier fits under the seat. Larger pets, and any pet on certain routes, must travel as cargo (manifest cargo or accompanied baggage). Some destinations, including the UK, Australia and the UAE, require cargo for almost all pets regardless of size.

Cabin: the rules of thumb

• Combined pet + carrier weight under the airline limit (often 8 kg, sometimes less).
• Soft carrier that fits under the seat in front of you.
• One pet per passenger; book the pet space early — cabins have a hard limit.
• Snub-nosed (brachycephalic) breeds may be barred from cabin and cargo for safety.

When cargo is required

Cargo is required for larger pets, for snub-nosed breeds on many airlines, and for destinations that mandate it. Cargo holds on pet-approved aircraft are temperature-controlled and pressurised. Book an IATA-compliant crate sized so your pet can stand, turn and lie down.

Make it calmer

Familiarise your pet with the carrier weeks ahead, line it with something that smells like home, exercise them before the flight, and avoid sedatives unless your vet specifically recommends them — sedation at altitude can be risky.

Check the destination page for your country: it shows whether cabin is allowed and which airlines commonly carry pets there.

FAQ

What's the usual cabin weight limit?

Often around 8 kg for pet plus carrier, but it varies by airline — always confirm with yours before booking.

Are brachycephalic breeds banned?

Many airlines restrict snub-nosed dogs and cats in cargo (and sometimes cabin) because they're more prone to breathing problems. Check the specific airline.

Should I sedate my pet?

Usually no. Sedation can be dangerous at altitude. Only do it if your own vet specifically advises it for your pet.
