The 10 Best Airline Approved Dog Carriers
Updated by · How we research
Ten soft under-seat bags for small dogs and cats, compared by fit, pet weight and airline rules. The Sherpa Original Deluxe leads for its squeezable frame. When users buy our independently chosen editorial picks, we may earn commissions to help fund the Wiki.
No government agency approves pet carriers. Each airline sets its own under-seat limit, and the plane decides the real space, so a bag's height matters more than any label on it. Delta, United and American list about 18 by 11 by 11 inches for a soft bag. This page is for owners of small dogs, or cats, who want them close instead of in cargo.

Editor's Notes
October 26, 2026, by Ezvid Wiki Admin:
The Sherpa Original Deluxe stays on top. It's still the bag pet-travel writers carry themselves, its back frame squashes under a low seat, and Sherpa refunds the ticket and pet fee if a registered bag is turned away for its size. The Sleepypod Air and the Mr. Peanut's Gold Series tote stay too.
Seven of the ten earlier picks are out. The Snoozer Roll Around, Kurgo Wander, X-Zone Pet, Texsens Bubble Backpack and FrontPet Travel are no longer sold. We dropped the SportPet Designs Kennel because it's a cargo crate, not a cabin bag, and the Natuvalle 6-in-1 because its high price came with little evidence. New picks cover a budget bag, a backpack, a squat model for low seats, a rolling one and an expandable one.
We checked each bag's size against Delta's posted pet rules, followed the TSA's checkpoint steps for pets, read makers' sizing charts and searched federal recall records for every brand. None had a carrier recall.
December 11, 2020:
When embarking on a journey with your faithful canine companion, always be aware of an airline's safety regulations and restrictions pertaining to travel with animals. Before taking your trip, we recommend contacting the airline directly and inquiring as to the specific guidelines required for bringing pets with you on a plane.
We've removed both the Jet Sitter Luxury and Teafco Argo Petagon due to availability concerns.
Newly added are the X-Zone Pet and FrontPet Travel, the former of which includes a removable baseboard and comfy fleece bed for a small breed canine while the latter, being similar in design to the Snoozer Roll Around, can be transported using its built-in wheels and telescoping handle.
When transporting a large pup, the Sport Pet Designs Kennel is still quite a relevant option due to its overall size and durability.
If you're looking for something truly unique in shape and design, the Texsens Bubble Backpack can definitely fit the bill. In addition to its synthetic leather and PVC construction, the semi-sphere transparent viewing window can be interchanged with mesh material, depending on the environment.
December 16, 2019:
Traveling with pets can be stressful for both the owner and the animal, but one of these high-quality carriers can help to make it easier on everyone. It is, of course, especially difficult to travel with large breeds, and the Sport Pet Designs Kennel is one of the best tools for doing so. It's an incredibly durable crate and built with helpful considerations like a small floor gutter to minimize the impact of accidents during cargo-hold travel.
With that out of the way, there are quite a few excellent choices for smaller dog breeds, and most of them work great for cats too. The Sherpa Deluxe is incredibly popular and has been for years; while itwa's relatively lightweight and flexible, it's also quite durable and offers plenty of ventilation, which can really help minimize claustrophobia issues. The Kurgo Wander is the only one that has more ventilation per square inch of its shell's surface area. The Sherpa also offers multiple entry and exit points, which not all models do. The Natuvalle 6-in-1 is another easy-to-use option with multiple entry points.
The Jet Sitter Luxury is especially durable and has a waterproof bottom that can come in handy in case of emergency. Both it and Mr. Peanut's Travel Tote are relatively affordable, and Mr. Peanut's in particular is styled much like a classy-looking piece of luggage. For a very different appearance, check out Texsens Bubble Backpack, which is quite unconventional and somewhat futuristic. It doesn't have much ventilation, which isn't always ideal, but its relatively closed-off nature can help with some dogs that have a more "out-of-sight, out-of-mind" approach to travel. The Teafco Argo Petagon is another highly stylish option, though it's pretty limited as far as the size of dogs it can accommodate. And if you are willing to spare no expense for your pup, the Sleepypod Air is probably what you want. It's one of the few that offers significant protection in the event of an automotive accident and it's very much a high-end piece of equipment. The only reason it didn't hold the number 1 spot on our list is the fact that it's several times more expensive than most competitors.
Whichever you choose, make sure that you acquaint your dog with it comfortably. In fact, it's a great idea to let your pup hang out in the carrier a bit even when you're not traveling so they're as familiar as possible with it. And for times when you're not flying, there are plenty of other great ways to transport your pets, whether you're walking or riding a bike.

Why "Airline Approved" Is Only A Label
Each airline writes its own rule, and the aircraft decides how much room there is under the seat in front of you.
No government agency signs off on pet carriers. The phrase on a bag means its maker thinks it fits common airline limits, and nothing more. Each airline writes its own rule, and the aircraft decides how much room there is under the seat in front of you.
Delta recommends a soft-sided kennel no larger than 18 by 11 by 11 inches and warns that the real limit depends on the plane. The pet must be able to stand and turn around, one pet rides per kennel, and the kennel needs to be leak-proof and ventilated on three sides for flights within the U.S. or four sides abroad. The pet stays inside the carrier at the airport and on board. Delta charges $150 each way within the U.S. and $200 on international routes, allows up to four pets in its main cabin and two in first, and doesn't take pets in the cabin to or from Hawaii, the U.K. or Australia.
Other airlines vary. A roundup by Where's the Frenchie lists about 18 by 11 by 11 inches for United and American, a shorter but wider bag for Southwest, and a 17-inch bag for JetBlue, which also caps the pet and bag together at 20 pounds. These numbers change, so check your airline's own page when you book.
Measuring Your Dog And Reading The Specs
Measure your dog from the nose to the base of the tail, and from the floor to the top of the head while sitting. Travelnuity suggests a carrier at least a couple of inches bigger than the dog each way. Sizes printed by makers are exterior and often include straps and pockets. Mr. Peanut's points out that padding eats into the inside, and that many airlines leave only about 8.5 inches of height under the seat.
Height is the number that decides most gate fights. A bag with a soft or spring-loaded frame can squash an inch or so to fit, while a bag with a wooden or plastic floor can't. Expandable side panels or pop-up roofs are for layovers: zip them shut before the bag goes under the seat. Weight limits on a bag are the maker's guess, not the airline's rule. Most U.S. airlines care more that the dog can stand and turn, though weigh-ins do happen, especially in Europe.
A dog over about 20 pounds rarely fits under a seat comfortably. The options are driving, a small airline such as JSX that lets dogs ride in a carrier, or the cargo hold, which many airlines limit and some ban for flat-faced breeds such as French bulldogs. A hard crate like the old SportPet kennel on this list is for cargo, not the cabin.
Security, Settling In And Safety
Pets never go through the X-ray. The TSA asks you to take your pet out at the checkpoint, send the empty carrier through the scanner, and carry the pet or walk it on a leash through the metal detector. A nervous pet can be screened in a private room if you ask. Put the pet back in the carrier once you're through.
Practice at home weeks ahead. Leave the bag open on the floor with treats and a worn T-shirt inside, then try short car rides, as Where's the Frenchie suggests. Book the pet spot when you buy your ticket, since airlines limit how many pets ride in each cabin, and check age rules: Delta requires puppies to be at least 8 weeks old for flights within the U.S.
No U.S. agency tests carriers for crash safety. The nonprofit Center for Pet Safety runs voluntary crash tests aimed at car travel, and Sleepypod says its Air passed for pets up to 18 pounds. Health certificates and import rules for other countries vary, so check them well before an international trip.
How we researched this
We compared 20 carriers, including every bag from the earlier version of this list, read makers' sizing charts and product pages, Delta's pet travel rules and the TSA's checkpoint guidance, and pet-travel writers' picks, and searched U.S. Consumer Product Safety Commission recall records by brand and for pet carriers generally.

Frequently asked questions
What makes a dog carrier airline approved?
No agency approves carriers. A bag counts as approved when it fits your airline's under-seat size, has mesh for air on several sides, closes securely and lets the pet stand and turn around.
Can a 20-pound dog fit under an airplane seat?
Rarely, and only a compact one. JetBlue caps pet and bag together at 20 pounds. Many airlines set no weight limit but require the dog to stand and turn inside a bag about 18 by 11 by 11 inches.
What size carrier does the TSA require?
None. The TSA screens pets but doesn't set carrier sizes. Airlines do, and many in the U.S. list about 18 by 11 by 11 inches for a soft bag.
How much does it cost to fly with a dog in the cabin?
Delta charges $150 each way within the U.S. and $200 on international routes. Other U.S. airlines charge similar fees. Book early, since each cabin takes only a few pets.
Does my dog go through the X-ray machine?
No. Take the dog out, send the empty carrier through the scanner, and carry the dog or walk it on a leash through the metal detector.
Do these carriers work for cats?
Yes. Every bag on this list is sized for small dogs and cats alike, and the airline rules are the same for both.
