The Best Cat Carrier for Airline Travel

Most cats aren’t going to thank you for sending them 39,000 feet up into thin air.  Flying with a cat isn’t ideal but it’s sometimes unavoidable. Therefore, choosing the best cat carrier for airline travel is crucial to making trips as safe, stress-free and comfortable as possible for both you and your pet.

Flying with a Cat Carrier

Always try to book your cat a ticket for inside the cabin rather than in the hold of the aircraft. Many airlines make allowance for this so long as the carrier can easily be pushed under the seat in front of you. We recommend that you use a soft-sided carrier (some airlines will insist that you do).

Unless it’s absolutely necessary, you should avoid putting the cat in the aircraft’s hold. It’s far safer for them to be inside the cabin with you. If the cat needs to travel in the hold of the aircraft, then you’ll need to buy a hard carrier without a top-loading door. Something like the Sky Kennel that we’ve listed below is ideal.

Each airline has a different set of regulations for carrying animals. Always check before booking a ticket what’s required to fly. Double check before you go, too, just to be on the safe side. Some cat carriers will say they’re ‘airline approved’ but there’s no uniform approval with each airline having individual requirements that you’ll be expected to adhere to in order to fly.

If you were looking for a cat carrier for long car trips, then we’d suggest one in which the animal could stand up, turn around and lie down in comfortably. This isn’t always possible when traveling inside an aircraft cabin. If the cat can lie down comfortably with enough room, then the cat should be fine. Check with the airline as to the maximum dimensions and measure your cat to make sure it’s enough.

You may be tempted to sedate your cat. You shouldn’t. Using medicine to calm cats for travel is relatively safe and common for car rides but it isn’t advisable if you’re flying. We wouldn’t even suggest Benadryl as drowsiness (one its side effects) can restrict an animal’s breathing making it dangerous for an environment with reduced air pressure. Spray synthetic pheromones such as Feliway into the carrier if you’re concerned that your cat might be nervous.


The Best for Most Airlines (cabin): Sherpa Travel Original Deluxe


This carrier is well ventilated with roll-down flaps providing privacy as well as reducing light to help your cat feel more safe and secure. It has a spring wire frame allowing the carrier to be pushed down by several inches in order to fit under the seat in front.  The top and side entry allows for easy access at all times.

There’s a carry strap, too, making it easy to hold and manoeuvre around the airport.  A faux lambskin liner will keep your cat warm and comfortable and it’s machine washable, too, in case of any messes. The handy side pocket allows for veterinarian notes to be kept close at hand as well as any special treats or toys.

You should always check with the airline before you fly about the requirements they have for transporting pets BUT Sherpa says this bag is approved for use on most airlines and that it’s included in their Guaranteed on Board Program.


The Best Hard Carrier for the Hold: Petmate Sky Kennel



If you’re putting your cat into the hold of an aircraft, then it’s even more important that you double-check the airline’s requirements and that you have a hard carrier.  

The Petmate Sky Kennel comes in 6 different sizes and is made from durable plastic and extra strong steel wire.  Its 4-way vault door gives additional security by helping to reduce the chance of a cat sliding or shifting the mechanism.  The ventilation is very good and it offers good visibility and fresh air on all sides.  Clip-on bowls are included as are 2 Live Animal stickers.  There’s a strong carry handle and its touted to meet most airline cargo specifications.

There’s no padding so you’d have to add your own blanket, towels or comforter to make this more comfortable for your animal.

In Amazon’s Q&A section are a ton of people who’ve flown domestically and internationally using the Petmate Sky Kennel without any problems but a few users have said that some airlines won’t accept latches or bolts that aren’t metal. Check before you fly. The latches can be replaced. One reviewer swapped them over for these.
