Flying with a cat takes more planning than choosing a carrier. You need a pet reservation, a carrier that meets your airline's rules for your exact flight, and the right documents for your destination. Check all three before you buy a ticket or carrier. Airline rules can change.
Confirm cabin travel before booking
Ask the airline operating each flight whether your cat can travel in the cabin, how to reserve a pet spot, the fee, any age or route restrictions, and whether your seat type allows a pet. Space for cabin pets may be limited. If your itinerary uses a partner airline or a connection, check every operating carrier. Delta's pet policy and American Airlines' pet policy illustrate why rules need to be checked by airline and itinerary.
Cabin and cargo are separate services. A carrier for a cat traveling under your seat is not automatically suitable for checked baggage or cargo. If your cat cannot meet cabin requirements, contact the airline directly about its current animal transport options and speak with your veterinarian about the risks and alternatives. This guide focuses on cats traveling in the cabin; it does not recommend a backpack or soft carrier for cargo.
Check the carrier against your exact flight
Measure the carrier's outside length, width, and height with it fully packed, and check the airline's current limits for every aircraft and cabin on your itinerary. The carrier must fit under the seat as the airline requires, remain secure and ventilated, and give your cat room to move comfortably within the airline's rules. Requirements for soft and hard carriers may differ. A label such as “airline approved” does not guarantee acceptance. No ILK carrier is represented here as TSA approved, accepted by every airline, guaranteed to fit under a seat, or suitable for cargo travel.
Compare styles in our range of cat carriers, then confirm the exact product dimensions and construction with your airline before purchase or travel. A backpack that works for a walk may fail an airline's under-seat or ventilation rules.
Prepare your cat and paperwork
Practice using the carrier at home well before departure. Leave it accessible, reward voluntary entry, and build up to short periods with the door closed at your cat's pace. See our guide to getting your cat comfortable with a carrier for gradual steps. Ask your veterinarian about your cat's fitness to fly, feeding, medication, and stress. Do not give sedatives or other medication without veterinary advice; the American Veterinary Medical Association cautions against tranquilizing pets for air travel.
For travel within the United States, the destination state or territory may require a health certificate, vaccinations, tests, or other documents; check its current requirements and your airline's rules. USDA APHIS explains interstate pet travel. For international travel, entry and return rules differ by country and may take months to complete. Work with your veterinarian and check the destination, transit, airline, and return requirements; use USDA APHIS pet travel guidance as a starting point. A rabies record or health certificate is not universally required for every domestic trip, and one document does not cover every international destination.
What happens at TSA screening?
At a U.S. airport checkpoint, TSA says to remove the pet from its carrier and put the empty carrier through the X-ray machine. Keep control of your cat and follow the officer's directions for screening; never place your cat in the X-ray machine. TSA advises using a leash for control and removing the leash while carrying the pet through the metal detector. If you worry your cat may escape, tell a TSA officer before taking them out and ask what screening options are available. Do not open the carrier early while waiting in line.
At the airport and on board
Allow extra time for airline check-in and security. Carry the booking confirmation and any documents required for your route. Keep your cat secured in the carrier except when screening staff direct you to remove them. The airline may require the carrier to stay closed and under the seat for the entire flight; check its current instructions. An absorbent liner and a familiar-smelling cloth can help with cleanup and comfort if your airline permits them, but avoid loose items that reduce usable space or airflow. For a long itinerary, ask your veterinarian and airline how to plan food, water, and safe breaks.
Before departure: reconfirm your pet reservation, carrier dimensions, destination documents, and rules for each operating airline. Recheck them if your aircraft or route changes.
