Flying with a cat is stressful, but one of the best airline-approved cat carriers can make it easier. When you place a cat at your feet in the plane cabin, a durable soft-sided carrier with some key features will ensure their comfort and safety, and your peace of mind.

To select the best pet carriers for flying with a cat, we spoke with a veterinarian and pet travel experts and tested 26 different airline-friendly pet carriers. Our top pick, the Sleepypod Air, is as durable as it is comfortable for pets and humans alike. If you're looking for a more affordable airline cat carrier, the simple Frisco Premium Airline Compliant Quilted Carrier Bag will keep your kitty comfortable from the beginning to the end of your journey.

Keep in mind that airline pet carrier size requirements vary by airline. Delta, American Airlines, and United allow pet carriers up to 18 inches (L) by 11 inches (W) by 11 inches (H). Some airlines have smaller maximum sizes, so make sure to check the airline's website before embarking with your pet.

The crash-test-certified Sleepypod Air has plush bedding, optimal ventilation, and a roomy interior to keep cats calm and comfortable in the air and on the ground.

Specifics

Our cat testers weren't shy about expressing their clear preference for the Sleepypod Air. During a recent trip to the vet, they both piled into the carrier, opting for its cozy sanctuary over their other carrier. The Sleepypod Air's plush bedding, just-right ventilation, and spacious interior proved calming and comfortable. For skittish fliers, the carrier includes a privacy screen you can slide through the mesh top, though this significantly reduces your cat's access to fresh air.

Among the best airline-approved cat carriers, the Sleepypod Air stands out for its innovative design and commitment to pet safety — it's certified by the Center for Pet Safety (CPS), a nonprofit consumer advocacy organization that researches and crash-tests pet carriers to ensure their safety. Rather than doors, it features one continuous zipper that runs end to end. With one pull of the zipper, the carrier transforms into an open bed, converts into a car seat, or rolls up for convenient storage. It's also designed to fold in approximately 2.5 inches at each end, meeting the size requirements of most major airlines. We recommend practicing compressing the bag before your trip.

The padded cross-body shoulder strap felt supportive, and the carrier rested comfortably against the body without collapsing inward. With the luggage strap, the carrier easily stayed balanced on a suitcase when rolling over curbs and rough sidewalks.

The Sleepypod Air isn't cheap. However, given its versatility, comfort, and impressive safety features, we believe it's well worth the investment. You can return it, used or unused, within a year, and Sleepypod guarantees a replacement if it's damaged in an auto accident.

Mr. Peanut's Gold Series Expandable Carrier unzips to almost double in size, providing a cat with extra room on long travel days.

Specifics

On long travel days with time spent in airports, Mr. Peanut's Gold Series Expandable Carrier offers jet-setting cats extra space to stretch out. It includes a zippered panel on its right side that unfolds into a mesh atrium that nearly doubles the carrier's interior space. While the expandable section can't be used in flight, this feature makes it the best airline-approved cat carrier for cross-country flights with layovers and extended stays away from home.

The spacious carrier is front- and top-loading with a roll-up privacy flap over the top door, and it offers plenty of ventilation to keep a cat from overheating. Inside, there is a soft plush bolster bed and safety tether. Outside, it has an adjustable padded shoulder strap and a faux leather carry handle. There is one 10-inch by 4-inch mesh pocket on the backside.

With sturdy mesh screens and smooth zippers, Mr. Peanut's carrier excelled in our testing. It was easy to spot clean, and although the bed is labeled hand-wash only, it came out of the washing machine looking nearly new after air-drying.

When we tested the luggage strap, the carrier remained mostly balanced on our suitcase, slipping only about an inch to one side. Carrying it on the shoulder was comfortable, and the strap was easy to adjust to the correct length.

Away's Pet Carrier has a sleek design and offers your cat maximum comfort and safety from point A to point B.

Editor's note: The Pet Carrier is temporarily out of stock.

We're big fans of Away's luggage line for its sleek design and thoughtful features. Now your feline companion can travel with the same sophistication and safety thanks to the Away Pet Carrier. Like the Sleepypod Air, it is crash-test certified by the CPS and has an interior safety tether to keep your pet secure between destinations. It replaces our previous favorite stylish carrier, the Diggs Passenger Travel Carrier, because it fits most major airline carrier size restrictions without the need to squish or fold in the sides.

Our feline tester loved the soft sherpa interior mat, making this carrier a prime napping spot at home and on the go. Mesh windows on two sides and the top provide excellent ventilation while giving your cat a sense of security. However, if your cat is a nervous flyer, simply roll down the privacy window for extra calm.

To navigate busy airports, you can slide the handy back sleeve over the handle of luggage from any brand. There's also an adjustable shoulder strap so you can wear it crossbody, and the carrier has just rigid enough construction so it won't collapse inward on your precious cargo. Or you can carry your cat using the leather hand strap.

This carrier's wipe-away nylon exterior and interior make cleaning up messes on the go easy. Even the pockets are nylon-lined, and the front pocket is waterproof with drainage holes, perfect for storing a collapsible water bowl. The machine-washable interior liner is secured by velcro and easy to remove, so you can toss it in the wash once you reach your destination.

This Frisco cat carrier is a cozy and budget-friendly option that holds up well to wear and tear.

Specifics

Although this carrier is a fraction of the price of our other picks for the best airline-approved cat carriers, it still performed well in durability testing. At home, it was also the carrier our tester cats consistently chose to lounge in time and time again. Simply put, the cozy Frisco Premium Airline Compliant Quilted Carrier Bag is an excellent budget airline cat carrier.

Susan Nilson, a cat and dog trainer and behavior specialist, recommends leaving a carrier with the doors open at home so your cat can get accustomed to it before travel. We did just that, and the carrier quickly became one of our cats' favorite spots to nap. Even after machine washing the interior fleece mat, it didn't lose its softness or cat appeal.

The carrier has two doors, top and side, and two storage pockets: a secure Velcro pocket to stash your keys and phone and a mesh pocket to keep your cat's treats and travel documents easily accessible. The included collapsible silicone bowl and ID tag ticks two essentials off your packing list.

The adjustable shoulder strap and carry handle lack padding and may become uncomfortable on longer journeys. Similar to pricier options, the Frisco carrier includes a luggage strap designed to attach the carrier to the telescopic handle of your suitcase. However, the strap doesn't keep the carrier well-balanced on curbs and sidewalks, so you'll want to have a free hand for added support.

Mr. Peanut's Monterey Backpack Carrier is a great option for busy travelers who prioritize feline comfort and hands-free transport.

Specifics

If you already have your hands full, Mr. Peanut's backpack carrier might be your best bet. It's a cat carrier you can wear on your back to keep your hands free and your cat safe.

The backpack prioritizes a cat's comfort with a wider profile similar to a traditional carrier. This design eliminates the need to turn the carrier — and your cat — on its side for stowing under the seat in front of you. It does sit a bit higher on my back than my favorite cat hiking backpack (reaching mid-back or higher depending on your height), but it's a small price to pay for a cozy feline friend. The adjustable, padded shoulder strap offers a carrying alternative but isn't long enough for a crossbody fit.

According to the brand, an interior machine-washable thermal pad is designed to keep cats comfortable in any climate. While I can't confirm its effectiveness at regulating temperature, my cats certainly approved of it as a napping spot. To test its ease of cleaning, I smeared a mix of dry and wet cat food on the interior and exterior. A quick wipe-down with a damp paper towel removed most of the mess from the nylon exterior. The interior quilted design trapped some dried food bits in the crevices, but the washing machine took care of the mess. A pre-wash scrub may be necessary for some dried-on accidents.

The carrier didn't take a toll on my back during walks, thanks to its mesh padding that offers breathability and cushioning. However, it lacks a waist or chest clip for added stability on long airport treks, so I tightened the shoulder straps to hold the carrier flush against my back. The carrier comes in medium and large, but only the medium size meets most airline carry-on restrictions.

The best airline-approved cat carriers come in many different styles at varying price points. To ensure you get the best value for safety and comfort, our experts recommend considering the following factors when shopping.

Safety: Unlike child car seats, there are no universal safety standards or inspections for cat carriers. However, some brands go the extra mile by subjecting their carriers to rigorous testing by reputable third-party or nonprofit safety organizations. Among our recommended picks, the Sleepypod Air and Away Pet Carrier have been crash-test certified by the Center for Pet Safety (CPS), a nonprofit consumer advocacy organization that studies the safety of pet products.

Currently, CPS studies do not extend to air travel and flight safety. Despite the absence of standardized air travel safety tests, crash-test certification remains the gold standard. As Lindsey Wolko, founder and CEO of CPS, points out, you'll want to consider your entire journey, including driving from your home to the airport and transportation at your destination.

Wolko says carriers are most susceptible to failure at seams where the mesh connects to the carrier body. She recommends inspecting carriers for any signs of loose threads, weak spots, or faulty zippers to ensure their overall safety and reliability throughout transit.

Size: A carrier should be roomy enough for your cat to comfortably turn around and lie down while still being compact enough to fit under the seat in front of you. Carrier size requirements vary by airline, so double-check your airline's specific requirements.

Fortunately, size isn't usually a limiting factor for cats. More often than not, they prefer to curl up in a small ball and hide during the trip, says Dr. Jo Myers, a veterinarian with Vetster. She says extra room for playing, eating, drinking, or using the litter box during the flight is typically unnecessary. However, if you anticipate a long layover and want extra legroom for your cat, an expandable carrier like Mr. Peanut's Gold Series Expandable Carrier is a good choice.

Weight restrictions: Many in-cabin cat carriers are suitable for cats weighing up to 15 or 18 pounds. If your cat is on the heavier side, double-check the weight limit for the carrier you're considering purchasing and make sure your cat has room to comfortably move around in the carrier.

Ventilation: Most carriers are designed with enough ventilation (at least 16%) to meet the International Air Transport Association (IATA) minimum requirement. Some carriers may have less or more, so the amount of ventilation you choose depends on you and your cat's preferences.

Since Myers says most cats prefer to hide in stressful environments, carriers with privacy walls and flaps may be beneficial. Alternatively, she recommends bringing a towel or blanket that you can place over the carrier if your cat becomes stressed. "Even if you cover the carrier with a towel, it's far from airtight," she says. "Simply check on your cat occasionally, without disturbing them any more than necessary."

We developed our selection and testing criteria for this guide to the best airline-approved cat carriers with advice from our experts. The 26 carriers we evaluated underwent the tests described here.

Feature comparison: After conducting interviews with our experts, we created a point rubric for scoring each carrier based on the following features:

Scrape test: We scraped a mesh section of each carrier 50 times with a fork to test its durability, noting any damage or discoloration.

Zip test: To test the durability of each carrier's zippers, we completely zipped and unzipped one of its loading entrances 50 times. In the process, we observed changes in the zipper's ability to smoothly run its course.

Luggage test: If a carrier included a luggage strap, we evaluated how well it remained balanced on top of a suitcase. We placed a 10-pound weight inside and attached the carrier to a suitcase handle so it rested on top of our luggage. Then we rolled it over a curb, up a ramp, and along the sidewalk and street of a city block.

Ventilation test: According to Wolko, ventilation is important to prevent a cat from overheating during travel. We measured the dimensions of each carrier's mesh panels and calculated the percentage of the total surface area they comprised. We favored bags with more ventilation. According to IATA live animal regulations, pet carrier bags must have a minimum of 16% ventilation.

Walk test: We took each soft-sided carrier containing a 10-pound weight on a 15-minute walk around a neighborhood. Each was carried using the shoulder strap and held at the front of the body the way a person would if they had a real cat inside. For the last block of the walk, we switched to using the hand-carry straps. The backpack carriers were taken on the same walk but were not carried by hand. With each one, we paid attention to how comfortable it was to carry, how much it bounced, and whether it collapsed inwards.

Goop test: We devised this test to determine how easy it would be to clean the carriers if a cat vomited or defecated in transit. We mashed together cat kibble, canned food, and water with a mortar and pestle to make the goop, then spread a tablespoon on an exterior wall and interior mat of each carrier. After 48 hours, we wiped the goop from the exterior using dish soap and water and cleaned the mats in the washing machine.

Drop and stomp tests: We brought the carriers to a local park, loaded each one with a 10-pound weight, and threw them off of a 10-foot play structure, looking for any damage that occurred upon landing. We then rolled the bags several times on the ground with the weight still inside, looking for damage to the stitching, mesh, or zippers. Later, at home, we placed each carrier on a rug and stomped on it a dozen times with bare feet, noting whether its frame changed shape or the bag suffered any other damage.

To fly with a cat in the cabin of a plane, you'll need a soft-sided carrier that fits within the allowable dimensions of the airline, which vary a little from airline to airline. Regardless of the carrier you use, Wolko says to make sure your cat has enough room to stand up, turn around, and lie down comfortably. Additionally, there should be at least 2 to 3 inches of clearance from the top of their ears to the interior roof of the carrier.

Fees for flying with a pet in the cabin of a plane vary between carriers. At United Airlines, a one-way flight for your cat adds $125 to your ticket price. At Delta, there is a $95 fee for domestic flights. Flying a cat in the cargo hold on a domestic flight is typically about $300 per trip. Sending a cat on an international flight can cost up to triple that amount.

For soft-sided carriers, Wolko says mesh ventilation should be on at least three sides of the bag. In cargo, airlines require that a kennel is ventilated on all four sides. According to the IATA live animal regulations, both soft- and hard-sided pet carriers must have a minimum of 16% ventilation.

Unless a cat has a medical condition, they will be fine without access to a litter box for the duration of a flight. "Just based on the physiology of cats, they could probably go from Boston to Hawaii without needing to void," says Dr. Bob Murtaugh, a veterinarian and chair of veterinary medicine for the National Academies of Practice.

In the cargo hold, kennels cannot be outfitted with a litter box or anything other than an absorbent liner and a soft bed or blanket. "If the travel day will be more than eight hours, during a layover pet owners can arrange a comfort stop for cats to be let out of their carrier," says Elaine Mathis, pet travel specialist and project manager at Happy Tails Travel. When you let your cat out of their carrier, you'll want to make sure your cat is safely secured with one of the best cat harnesses attached to a leash.

On shorter in-cabin flights, it's unlikely your cat will require food or water. However, if you're flying your cat in cargo, Mathis says a food bowl and water bowl should be in the carrier regardless of the flight length. She recommends using dishes that fasten to the crate's door and can be refilled easily from the outside, such as Lixit's Quick Lock Crock 10-ounce bowls.

According to Murtaugh, a few obvious signs may indicate your cat is in distress during a flight, either due to fear or excessive heat. A cat that is panting, restless, and vocalizing could be experiencing significant anxiety or overheating. If the membranes in their gums turn bright red, the latter is most likely, and it's important to cool them off quickly. If a flight attendant approves, placing the carrier on your lap so they can feel the air blowing from the vent above your seat or wiping them down with a wet cloth may help lower their body temperature. Before your travel, Nilson recommends lightly spraying the carrier with calming pheromones.

In the weeks before their trip, introduce your cat to their carrier or kennel in a positive way. "Make the carrier feel like a cave or a home or something that's comfortable, something that they're not just jammed into the first time they're on their way to the airport," Murtaugh says.

Place the carrier in an area of the home where your cat spends a lot of time and encourage them to explore it by placing catnip and treats inside or by playing with them in and around the space.

Murtaugh says that taking your cat on a car ride or other forms of transportation while in their carrier may also be helpful in the weeks before the flight. He recommends placing a bed or blanket that smells like home inside the carrier and using a pheromone spray or collar to help take the edge off.

If your cat has a history of experiencing debilitating stress during travel and will be flying in the cabin, you can speak to your vet about prescribing an anxiety-relieving medication. However, it's important to test medication out before your flight. "Make sure there won't be any untoward side effects," Murtaugh says. "Your vet can help you tailor that to your cat's needs."

The IATA recommends against sedating a cat before flying in the cargo hold. It can be fatal for older, chronically sick, or highly stressed animals. Nilson says calming pheromones such as Feliway or Pet Remedy are safe alternatives.
