Cats might be territorial but us humans often have to be more flexible with where we work and where we live. 

We can drive long -distance with our cats in our cars and we can take epic bus or train journeys with our pets but sometimes we have no choice but to fly. It’s rarely an ideal situation.

A quick word on ‘airline approved’ cat carriers

Airlines have strict regulations on carriers and breeds which can add to the amount of work you probably already have in arranging your own relocation.

Choosing the best cat carrier for airline travel is one way you can help make your trip as safe, stress-free and as comfortable as possible for both you and your pet.

It’s worth mentioning that all airlines have different requirements for cat carriers.

You should always check directly with the airline before you book. Information on the internet can be out-dated so don’t rely on blogs or websites when ordering a crate or carrier.  Some manufacturers will say theirs is an airline approved cat carrier but with so many airlines it’s really not possible for them to promise that without some risk of error.  The last thing you want is to turn up at the airport only to be told that your pet can’t fly.

That being said, in-cabin carriers are usually fine so long as they’re soft-sided and can be pushed under the seat in front of you.

If you’re just browsing before buying, then that should be enough of a guideline to give you some idea of what’s available.

Remember, too, that there are different requirements for traveling in the cabin of the aircraft and the hold.  We’d always advise that you try to get your cat into the cabin with you.  It’s more dangerous for pets in the hold.

How to choose the best cat carriers for planes

  • We said it earlier in this post but it’s worth repeating: check with the airline what size they accept.  For travel in the hold, you’ll also need to check about top-loading carriers and what kind of lock or latch system they’d like you to have.
  • If your cat is nervous or aggressive, then a soft-sided carrier can be tricky because it’s easier to damage.  Look for carriers made from durable fabric with zippers that can’t easily be undone.  Some cats prefer to be able to see what’s going on and others prefer to be covered over so bear in mind you may need to take a sweater to cover over it.
  • There are expandable cat carriers (we’ve included one below) which conform to in-cabin airline regulations but which can also be opened out slightly in the terminal or once onboard allowing the cat more room to move. This might but useful if your cat is slightly larger.
  • Carriers with pockets are useful for keeping documents and treats easily to hand.
  • We’d recommend adding a lease or harness if you don’t already have on.  At security, you’ll have to take your cat out of its carrier and it’s far easier if they’re already on a leash.  The added security when they’re in the carrier should help reassure you that they’re safe, too.
  • Before purchasing, it’s always a good idea to read the reviews from verified buyers. Many of them will have included photographs and experience of using that product.  This will give you a better idea of what to expect than product specifications alone.
  • There are additional requirements for pets traveling in the hold of an aircraft.  You’ll need to ensure you have ‘live animal’ stickers as well as drinking bowls.  Some carriers include these with the carrier but you’ll need to buy some if not.
  • Some owners add puppy training pads to the bottom of the carrier in case there’s an accident. This will help absorb any mess.  You’re unlikely to fit a litter tray inside a cat carrier for airline travel but most cats wouldn’t use it anyway.  You could pack disposable litter trays for use in a completely contained bathroom stall when you’re at the airport and when you arrive.
  •  We wouldn’t recommend buying sedatives for traveling by plane. Some airlines will insist that you don’t do it as the reduced oxygen at altitude can cause distress in pets.  If you’re worried about your cat getting anxious, then you could use a cat calming spray on the inside.


5 best cat carriers for air travel

The Best for Small Cats Pet Magasin Luxury Soft-Sided Cat Carrier

This is one of the few carriers that seems specifically designed for cats rather than dogs. It’s small enough to be carry-on approved by major airlines – although, please double-check before booking – its dimensions are 18″ x 11″ x 10″.

Empty it weighs only 2.2 pounds but benefits from durable material with mesh windows, plenty of ventilation and comfortable internal padding.  There’s a padded shoulder strap, too. This folds flat for storage and is easy to clean.  The material is waterproof. The packaging suggests it’s ‘resistant to animal bites’ which is very good news if your cat is anxious.

It’s ideal for traveling by car, too, which makes it more versatile compared to other pet carriers.  It has tear-resistant mesh and is suitable for cats up to 18 pounds.  We all know going through the airport can be a big hassle but this has a pocket for documents or treats.  There’s also a safety tether to help prevent escapes.

One of this carrier’s best features is that you can expand the sides out to create a bigger space.   This would be so helpful in the terminal before your flight or during a connection.  Always check with the airline before you fly but the manufacturer says it’s been designed to fit under the seats of most major airlines
