Short answer: Many airlines let a cat fly in the cabin on international flights if the cat plus carrier stays under 8 kg (17.6 lb). That’s the limit on Lufthansa, Air France, KLM, Turkish Airlines and Etihad; Air India allows 10 kg. United sets carrier dimensions instead of a weight cap. Emirates, Qatar Airways, British Airways and Singapore Airlines don’t allow pet cats in the cabin, and routes to the UK, Australia and the UAE are commonly excluded. One-way cabin fees we found range from USD 150 to USD 399.
Cats generally have an easier path to in-cabin international travel than large dogs, because most cats fit comfortably within carrier limits. Easier doesn’t mean simple, though. There are still real airline and country rules to sort out before you book.
What Do Airlines Allow for Cats in the Cabin?
From each airline’s own pet page, for international flights:
| Airline | Cabin limit | Carrier size | One-way fee |
|---|---|---|---|
| Lufthansa | 8 kg including carrier | 55 × 40 × 23 cm | Route-dependent |
| Air France | 8 kg including carrier; one animal per passenger; not in intercontinental Business | 46 × 28 × 24 cm | USD 200 US/Canada–Europe; USD 250 US/Canada–rest of world |
| KLM | 8 kg including pet; Economy only on intercontinental flights | 46 × 28 × 24 cm | EUR 70–500 |
| Turkish Airlines | 8 kg; window seats only | 40 × 30 × 23 cm, soft-sided | Online calculator |
| Etihad | 8 kg including carrier; at least 16 weeks old | 40 × 40 × 22 cm (larger with an extra seat) | USD 399 (Economy) |
| Air India | 10 kg; one pet per passenger; last-row aisle seats | Soft kennel 17 × 10 × 9 in | USD 140–225 on international routes |
| United | No weight limit; up to 2 pets per person with 2 seats | Soft 27 × 45 × 27 cm; hard 22 × 44 × 30 cm | USD 150 |
| Delta | Main Cabin/Comfort only; 4 pets per flight | Soft kennel 18 × 11 × 11 in (recommended) | USD 200 international |
No pet cats in the cabin: Emirates, Qatar Airways, British Airways and Singapore Airlines. American Airlines doesn’t allow carry-on pets on transatlantic or transpacific trips.
Which Routes Are Commonly Excluded?
Route rules catch out more cat owners than weight limits do:
- UK: KLM, Turkish, United, Delta, Air India and Etihad (to London and Manchester) exclude cabin pets, and British Airways carries no pets in the cabin at all.
- USA and Canada: Air India doesn’t allow cabin pets on flights to America or Canada, and Etihad doesn’t allow them to the USA. That rules out a cabin cat on both carriers’ India–US routes.
- UAE: United and Delta exclude it, and Air India doesn’t allow cabin pets on flights from India to the UAE.
- Australia and New Zealand: United, Delta and Air India exclude them.
Lufthansa also says it may refuse cabin pet bookings on certain routes, and it recommends booking the pet when you book your own seat because space is limited. Our guide to airlines that allow pets in the cabin on international flights covers dogs and the full picture.
What Should You Check Separately From the Airline’s Policy?
The destination sets its own rules, whichever airline you fly:
- US: the CDC requires only that cats “appear healthy upon arrival,” with no federal rabies proof. See importing a cat to the US from India.
- EU: a microchip, then rabies vaccination with a 21-day wait, and for countries the EU doesn’t list, such as India, a rabies antibody test at least 90 days before the certificate. That’s according to the European Commission.
- India: an Advance NOC applied for at least 7 days before you fly, and a cat examined within 7 days of shipment. See getting an NOC to import your pet to India.
- Health certificate timing varies by destination. Our guide to pet health certificate requirements explains the windows.
What About Large or Flat-Faced Cats?
- Big cats: a large Maine Coon can exceed 8 kg with its carrier. Weigh your cat inside the packed carrier before booking. If it’s over, Air India’s 10 kg limit or United’s size-based rules may work, or the cat flies in the hold.
- Flat-faced cats: Persians, Himalayans, Exotic Shorthairs and similar breeds are refused in the hold by many airlines, including Lufthansa, Air France, KLM and Turkish Airlines, but can usually fly in the cabin. See relocating a Persian cat internationally.
How Should You Prepare a Cat for a Long Flight?
Cats travel best in a carrier they already know. Leave it out at home for weeks, feed treats inside it, and take short car trips. Lufthansa suggests getting pets used to the closed container “several times for about two hours at a time.” Line the carrier with an absorbent pad and a familiar-smelling cloth, and carry spare pads and a few zip-lock bags. Don’t sedate. The Australian Veterinary Association says dogs and cats “should not be sedated for air transport,” and IATA agrees.
What’s the Best First Step?
Check the airline’s pet page for your exact route, then book the cat’s cabin space when you book your own seat, because per-flight limits fill early. Separately, confirm the destination’s import rules on its official government page.
