With an overall 4.6-star rating after over 1,400 reviews, the Sherpa Original Deluxe pet carrier is a favorite among pet owners. It features a flexible wire frame that’s easy to push under airline seats, and large mesh windows provide lots of ventilation for your pet.

The carrier also has convenient top carry handles, an exterior pocket, and a padded shoulder strap that’s adjustable for comfort. Plus, the luggage strap doubles as a seat belt security strap, so this carrier is great for car trips, too.

The carrier comes in seven colors and three sizes.

All you have to do is head to the company's website and provide flight information, then you'll receive a form guaranteeing you'll be able to bring your pet along, otherwise the company reimburses your flight costs.

An enthusiastic review: “I purchased this kennel for my cat, to use during her (unaccompanied!) journey from the US to the UK. The trip involved a 3.5 hour drive, followed by about 35 minutes of walking around lost in Newark Airport, and then a 6 hour flight to Manchester. Little miss kitty had an entirely safe journey and was back to her curious self again by the evening after she landed!”

If carrying your cat puts too much strain on your back and shoulders, this carrier with wheels is good for pets up to 25 pounds and can help you comfortably breeze through the airport. The soft-sided carrier rests on a four-wheeled platform with a telescopic handle, and there are also hand straps and an adjustable shoulder strap for those times when you need to lift it. There are mesh windows for ventilation, side and top zippered openings, exterior pockets, and a machine-washable fleece pad to keep your cat comfy. Keep in mind, some reviewers mentioned having to detach the wheeled platform to fit the carrier under their airplane seat — but that’s easy to do, and you can also fold the carrier flat for convenient storage when your trip is over. A collapsible bowl is also included.

An enthusiastic review: “[...] In order to slide it under the seat in front of me on a plane I had to remove the wheels but that was quick and easy to do. Over all it worked very well for both a long car ride over Thanksgiving and a 3 hour plane trip.”

An enthusiastic review: “I got this for my 8 month old cat who weighs about 10 pounds and she fit with plenty of room to spare. I take my cat out for travel regularly using this carrier and I can barely notice a weight on my back when I carry her. The adjustable straps and back padding were added bonuses.

For the best overall pick when you're shopping on a budget, this soft-sided carrier really is a must-own. Designed to be lightweight yet still durable, it comes with four soft sides and mesh panels for better ventilation. Since this has a padded shoulder strap, you can carry it with you easily as a tote, or carry it using the top handles. While this carrier isn't ideal for all breeds since it can only carry pets up to 8 pounds, it's more than enough if you're traveling with kittens or a single average-sized cat. This also has a small zipper pocket on the side exterior, which makes for convenient additional storage.

An enthusiastic review: “The cat carrier is exactly as described and is perfect for my little cat. She fits perfectly in it with room to spare. There are ample openings so that the kitty gets plenty of air. I would recommend this product to anyone looking for a carrier for a small fur baby.”

This highly rated cat carrier gives kitties space to stretch out, even when they're in a packed cabin in the air. Made with mesh panels and a convenient wire frame that adds extra support to this carrier, it's definitely one of the most flexible options you can invest in before a long trip. It comes with a shoulder strap, two zipper doors, side pockets for storage, and a soft fleece pad for cuddling. This medium-size carrier is good for cats up to 13 pounds (the large size accommodates kitties up to 18 pounds) and it works especially well for longer international flights since it gives cats a little opportunity to roam. While reviewers definitely recommend checking with your airline's rules and regulations before traveling with this, it's a terrific option that could help your pet feel less anxious during flights.

An enthusiastic review: “Able to use for Delta flights! Once we got our seats just opened one side, opened another later. Our cat really hates small space like pet carriers but had been so calm during 6 hrs flight [...] Inside of the carrier is fluffy and she started being comfortable once she understood no one was gonna get her out.”

Upgrade your cat to first-class instantly with this amazingly welcoming mobile pet bed. Designed to function as a car seat and in-cabin airline carrier for pets, it can fit cats up to 18 pounds and is one of the poshest options for traveling that you'll ever come across. Crash tested for car use and certified with a four-star rating from the Center for Pet Safety, this tear-resistant carrier also comes with a trolley pocket, so you can attach it to your luggage instead of having to carry it over your shoulder. Because the Sleepypod Air has such a unique design, it contracts in size to fit in the space below most airline seats during the restricted takeoff and landing times. However, once your plane is actually in the air, you can expand the carrier to allow your pet more space below the seat.

An enthusiastic review: “We have been a fan of this carrier for years. It is comfortable to carry, the cats love them. They are sturdy and a bonus is that they look great [...] They work great on planes (used on the flight back from Germany with our 15# cat) and for trips to the vet.”

An enthusiastic review: “I use this carrier to take my cat with me on Delta flights. This is the best flight carrier I have used so far because of three features. The case is designed to fit under the airline seat either standing up, or on it's side, making it possible to go on big planes and small planes. The materials are high quality, and there are several options to carry your cat. The backpack straps do work; there is an over the shoulder strap, and there is the regular hand carry handles [...]”

An enthusiastic review: “This cat carrier is excellent, it holds my 12 pound cat comfortably, and it is sturdy enough that I have had no issues with it collapsing despite it being a soft-sided carrier. The multiple entrances make it easy to load him up, and the expandable side gives him the opportunity to stretch out on car rides.”
