Flying With a Cat: Airline Rules, Carriers and Calm Travel Tips

By Tailwisp Editorial TeamUpdated October 20, 20264 min read

Flying with a cat takes planning, but many cats travel well when prepared. Airline rules differ, and requirements change, so always check directly with your airline and destination. This guide offers general advice to help you plan a safe and calm trip.

Should your cat fly?

Flying is stressful. Cats with heart or breathing problems, flat-faced breeds and very anxious cats may be at risk. Talk to your vet before booking. For short trips, consider a cat sitter instead. See cat sitter vs boarding. If you are moving, flying may be necessary. See moving house with a cat.

Cabin or cargo?

In the cabin. Most cats travel in an airline-approved carrier under the seat in front of you. This is generally the safest option, because you can monitor your cat. Airlines limit the number of pets per flight, and charge a fee.

As checked baggage or cargo. Some airlines allow pets in the hold, but temperature extremes and handling carry risks, and many airlines have restrictions, especially in hot or cold weather. Most vets and animal welfare groups advise avoiding it if possible.

Pet transport services. Some companies arrange pet travel, which may suit international moves.

Airline rules

Check the following with your airline:

• Maximum carrier dimensions, which vary.
• Weight limit for cat and carrier combined.
• Fees, and whether you must book in advance.
• Number of pets allowed per cabin.
• Seat requirements, since the carrier must fit under the seat, and some seats such as exit rows do not allow it.
• Breed or age restrictions, and temperature embargoes.
• Required documents.

Book early, and confirm in writing.

Carrier

Choose a soft-sided or hard-sided carrier that meets the airline's size limit, with good ventilation and a secure latch, and a leakproof base. Your cat must be able to stand and turn. See how to choose a cat carrier. Label the carrier with your name, phone number and destination.

Training

Start weeks before the flight. Make the carrier a comfortable place, with treats and a blanket. Practice car trips. See carrier training a cat and how to travel with a cat by car. Consider a trial walk with the carrier through a busy area. Using a calming pheromone spray on the blanket may help some cats.

Health and documents

• Vet visit. Check that your cat is healthy and vaccinated. See cat vaccination schedule.
• Health certificate. Many airlines and destinations require a certificate issued by a vet within a set number of days before travel.
• Rabies certificate. Required for many destinations. See rabies and cats.
• Microchip. Required for international travel. See cat microchipping and identification.
• Import rules. Check the country's requirements, which can include tests and waiting periods.

Sedation

Most vets and airlines advise against sedating cats for flights, because sedatives can affect breathing, balance and body temperature at altitude. If your cat is very anxious, ask your vet about safer options, such as calming products, or a trial run. Never give sedatives without veterinary advice.

At the airport

• Arrive early.
• At security, you will be asked to remove the cat from the carrier and carry it through the metal detector, while the carrier goes through the scanner. Use a harness and leash, or hold the cat firmly, since cats can bolt. See harness training a cat.
• Keep the cat in the carrier at all other times.
• Do not feed a large meal before the flight.

On the plane

Keep the carrier under the seat, and cover it with a light cloth if your cat is calmer in the dark. Speak softly. Do not open the carrier. Many cats sleep. Bring a pee pad in case of accidents. Avoid dry food just before landing.

Supplies to pack

• Food, water and a collapsible bowl.
• Pee pads and bags.
• A spare blanket.
• Medication.
• Copies of documents.
• A harness and leash.
• A small litter tray for the destination.

After landing

Take your cat to a quiet place, and offer water and litter. Watch for signs of stress. See cat emergency warning signs.

Connecting flights and delays

Direct flights are best, since each connection adds stress and the risk of delay. If you must connect, check that the airline allows a layover with a pet, and find the airport's pet relief areas. Carry extra food and a pee pad in case of delays. If the flight is cancelled, ask the airline about pet policy when rebooking, since cabin slots for pets are limited. Keep your cat's documents in your carry-on, not your checked bag, and take copies on your phone.

When to see a vet

See your vet before the trip to confirm your cat is fit to fly. Use the US vet directory to find a clinic.
