Pet-friendly airlines with in-cabin accommodations (US and beyond)

Pet-friendly airlines with in-cabin accommodations (US and beyond) - cat sitting in luggage

Air travel is sometimes necessary for one reason or another, all the more so around the holidays. Some enjoy it; some would rather stay grounded.

Air travel is always more stressful if you have to leave your furry friend behind. You may try to bring them along only to encounter the insistence that pets must ride in cargo. While most pets flown in cargo are fine, there's always a risk of excessively hot or cold temperatures, poor ventilation and/or rough handling.

With that in mind, you’ll want to make sure the airline you choose allows pets in-cabin, so you can check in on them throughout the flight.

Pet-friendly airlines with in-cabin resources are, luckily, not uncommon. However, they can only accommodate so many pets per flight, so traveling with your pet often requires you to book as early as possible.

Even if you’ve purchased accommodations for them ahead of time, pets can be denied boarding at the gate due to disruptive behavior, such as:

  • Scratching
  • Excessive whining, barking, or growling
  • Biting
  • Lunging
  • Urinating or defecating in the cabin or gate area

Airlines that allow dogs in-cabin also have a few other general rules in common:

  • Pet carriers are classified as your carry-on item
  • Carriers must fit beneath the seat in front of you and not exceed size and dimension requirements
  • Pets must be able to stand and move in their carriers comfortably
  • Pets must be well-behaved and non-violent
  • Dogs/cats must be at least 8 weeks old (some airlines require older)
  • Most airlines restrict or recommend against flying with brachycephalic breeds
  • Pets cannot travel with unaccompanied minors

Other than that, rules and norms vary from one airline to another. We’ll go over those as well as some airlines that allow large dogs in-cabin as of 2022.

(Note: prices below are given in USD. Airlines that charge in Canadian dollars (CAD) generally charge the same, numerically, as they charge in USD. European airlines charge in Euros. At the time of publication, the USD and the Euro are valued at roughly 1:1. To keep things consistent, European prices are listed in USD.)

Pet-friendly airlines in the US

Alaska Airlines

Alaska Airlines charges a $100 (each way) in-cabin pet fee. But there are limits: only three pets can ride in first class, and 8 in coach, per flight—so book as early as possible to secure a spot.

Odorous or noisy animals must travel in the baggage compartment, so make sure to bathe your buddy beforehand and try to help them stay calm as much as you can.

American Airlines

American Airlines limits their in-cabin accommodations to dogs and cats that meet the appropriate size and weight limits. The combined weight of your pet and their carrier cannot exceed 20 lbs., and they must be able to fit under the seat in front of you.

One pet is permitted per kennel with a few exceptions. One female cat or dog may travel with her un-weaned litter if the litter is between 10 weeks to 6 months of age. There is no limit on the number of animals in the litter. Additionally, two pets of the same breed and size between the age of 10 weeks and 6 months may be allowed to travel in one kennel as long as they are small enough to fit into a single kennel and are compatible. They will be charged as one pet.

One-way pet fees vary depending on destination:

Pet carriers must fit under the seat in front of you; maximum dimensions are 18" L x 14" W x 8" H. They do not allow any pets to be checked as baggage—that is, pets can’t travel in the cargo hold. Meaning large pets won’t be flying Frontier.

Southwest accepts small, vaccinated cats and dogs, except on international flights or flights to or from Hawaii. They allow a total of six pet carriers per flight, each of which can measure no more than 17” L x 10” W x 9.5” H. The pet travel fee is $95 each way.
