The Most Pet-Friendly Airlines of 2023 (2024)

Jet-setting pet parents know just how heartbreaking it feels to leave a belovedfurry friend at home while traveling. Fortunately, there are manypet-friendly airlines that allow dogs, cats, birds, and a handful of other household animals to fly with you to your destination.

Flying with pets requires a little extra leg work, however. Eachpet-friendly airline has different—and, at times, confusing—policies about the types of animals allowed on planes, where they can spend the flight, which destinations they’re allowed to travel to, and what time of year they can fly. Airlines also charge varyingpet fees for passengerstraveling with a pet.

When determining which flight to book, carefully read each airline’s pet rules for ​​non-emotional support, non-service dogs and cats to ensure you and your furry friend have the smoothest experience possible. Also review the pet regulations at your destination, as many international locales, and even some domestic spots like Hawaii, have strict rules and procedures for bringing pets with you.

Ahead of your next trip, consider these pet-friendly airlines that allow dogs, cats, and other animals onboard.

Which airline is the mostpet-friendly?

There is no one-size-fits-all approach toflying with pets. Themost pet-friendly airline for your journey depends on the type of animal you have, your pet’s size, where you’re traveling, and whether you’d like your pet to fly in the cabin or in the cargo hold as checked baggage.

What airlines allow pets as carry-ons?

Many airlines allow pets to fly in the cabin as a carry-on, so long as they stay inside a carrier that’s small enough tofit under the seat in front of you for the duration of the flight.Southwest,Alaska,United,American,Delta,Hawaiian,Spirit, andFrontier are some of the airlines that allow pets as carry-ons.

Can I buy a seat for my dog on an airplane in 2023?

Most pet-friendly airlines do not permit travelers to buy their dogs a seat on a plane. Small dogs can typically accompany you in the cabin, however, mostairlines require them to remain inside a kennel tucked under theseat in front of you for the entire flight.

JetBlue, for example, requires travelers to pay for a second seat (and pay a second pet fee) to bring two pets onboard the plane at the same time. And even though you’ve paid for a second seat, you still need to keep your dog inside a carrier for the whole flight. Similarly,Alaska Airlines allows travelers to bring up to two pets with them in the cabin if they buy two seats next to each other on the flight.

Alaska Airlines

Pet travel in the cabin: For $100 each way (or $105 for flights departing from Canada),Alaska Airlines allows passengers to bring dogs, cats, rabbits, and household birds in the cabin. There are no breed restrictions for pets totravel in the cabin, however, AlaskaAirlines requires carry-on dogs and cats to be at least eight weeks old and able to eat solid food. Travelers must be at least 18 years old beforetraveling with a pet in the cabin.

Each passenger can bring up to two pet carriers with them in the cabin, as long as the traveler purchases two seats next to each other on the plane. Additionally, up to two pets of the same size and species can fly together in the same kennel, so long as they fit comfortably.

Pets must stay in their carrier, with all doors and flaps secured at all times, while onboard the plane, as well as in the boarding area. Travelers must stow the kennel under theseat in front of them during taxi, takeoff, and landing. The pet carrier counts toward the passenger’s carry-on baggage allotment, and travelersflying with pets cannot sit in the emergency exit or bulkhead rows. Alaska also limits the number of carriers onboard per flight: three in first class and eight in the main cabin.

Pets in cargo: Alaska Airlines allows a more diverse selection of pets to fly in its climate-controlled cargo hold for $100 each way: dogs, ferrets, guinea pigs, hamsters, household birds, non-poisonous reptiles, pot-bellied pigs, rabbits, and tropical fish. Regardless of the type of animal, travelers must provide a validhealth certificate for each pet.

Dogs and cats must be at least eight weeks old and able to eat solid food. AlaskaAirlines only allows one dog or cat of any size that’s six months or older to travel in a kennel; the same rule applies for pets that weigh more than 20 pounds and are between the ages of eight weeks and six months old. However, two puppies or kittens may travel together in the same kennel if they weigh less than 20 pounds, are between eight weeks and six months old, and are similar in size.

There are also restrictions based on outdoor temperatures in certain destinations Alaska Airlines flies to, as well as limits on pet cargo travel on certain flights during the holidays. Alaska also has rules around whenpets can fly to Hawaii, which experiences strong headwinds during some months.

Southwest Airlines

Pettravel in the cabin: Southwest Airlines permits small, vaccinated dogs and cats that are at least eight weeks old to fly with travelers in the cabin for a $95pet fee each way.Furry friends cannottravel in the cabin oninternational flights, nor on flights to Hawaii.

However,Southwest Airlines only allows six total carriers on each flight, and those spots are available on a first-come, first-served basis. Travelers must make a pet reservation withSouthwest Airlines over the phone. Then, on the day of the flight, travelers must go to the ticket counter at the airport to check in their pet and pay the fee.

Pets thattravel in the cabin must remain inside their carrier for the whole flight (and the kennel must be stored underneath theseat in front of you), as well as in the gate area and during boarding and deplaning. Up to two pets of the same species may travel together in a carrier, but they must be able to stand up and move around while inside. A kennel counts as either your personal item or a carry-on bag. The airline sells Southwest-branded pet carriers for $58, but travelers can also bring their own.

Even thoughSouthwest Airlines has an open seating policy for passengers, travelers with pets may not sit in the emergency exit seats or in rows without under-seat storage in front of them, such as the first row. Unaccompanied minors cannot bring pets with them into the plane.

If your four-legged friend passed away recently and you want to bring her cremated remains on the flight, you’ll need to bring them as a carry-on item—Southwest Airlines does not allow cremated pet remains in checked luggage. The airline recommends a temporary plastic or cardboard container so that the remains can pass through X-ray screening at security with ease.

Pets in cargo: Southwest Airlines does not have a pet cargo or shipping program, so the only way to bring your pet on a Southwest flight is byflying in the cabin.
