Alaska Airlines

Alaska Airlines passengers are permitted to fly with their pets in cabins and in baggage or cargo holds. However, you must reserve your pet’s spot on the plane in advance, and space is limited. You can book a reservation for your pet by calling Alaska Airlines’ reservations line at 1-800-252-7522.

Pets in cabin

Pets are allowed with their owners in the aircraft cabin on most flights. Only one pet carrier per first class cabin flight is allowed, and up to five pet carriers per flight are permitted in the main cabin.

To carry your pet on board with you, you must be at least 18 years old and have a ticket for an approved seat. Passengers seated in the emergency exit row, for example, may not have an in-cabin pet. Alaska Airlines doesn’t require a health certificate for in-cabin pets, but your arrival state may require proof of vaccination and other documentation.

Keep in mind your pet carrier counts as a carry-on item that replaces either your personal item or standard-size carry-on. If you’ve purchased two main cabin seats next to each other, you’re permitted to bring a maximum of two pet carriers, which must fit under the seat in front of you. If you have two pets, such as two cats of a similar size, they may be placed in one carrier, as long as they’re comfortably contained.

Kennel guidelines for in-cabin travel on Alaska Airlines

Carrier type Dimensions
Hard-sided 17"L x 11"W x 7.5"H
Soft-sided 17"L x 11"W x 9.5"H

Pets in cargo

Generally, household pets are permitted in the baggage hold of Alaska Airlines flights. According to the airline’s policy, this includes cats, dogs, ferrets, guinea pigs, hamsters, household birds, non-poisonous reptiles, pot-bellied pigs, rabbits, and tropical fish.

Cats and dogs must be a minimum of eight weeks old and weaned to travel, and combined pet and carrier weight must be 150 pounds or less. Currently, flights using Alaska’s Airbus aircraft are unable to transport pets in the cargo hold or in the first class cabin due to lack of heating in these areas. See your flight itinerary to find out what type of aircraft is being used for your trip. Also, PenAir flights outside of Alaska do not allow pets to travel in the baggage hold.

When you check in to your flight, you’re required to fill out a pet check record that states that you’ve offered food and water to your pet before dropping them off with the airline. If you have a connecting flight, Alaska doesn’t transfer your pet for you; you’re responsible for rechecking them at the connecting location.

Cost to fly with your pet on Alaska Airlines

To fly with your pet — whether in-cabin or checking it in baggage — Alaska Airlines charges a $100 pet fee, each way.

Pet restrictions on Alaska Airlines

Dogs and cats that are brachycephalic (i.e. “short-nosed”), aren’t allowed to travel in Alaska Airlines cargo holds due to breathing risks. Examples of dog breed restrictions include American pit bulls, Brussels griffon, bulldogs, and pugs. Cat breeds such as Burmese and Persian, among others, are also restricted.

Your destination may also impact your ability to bring your pet on Alaska Airlines. For example, certain destinations such as Canada, Costa Rica, Mexico and Hawaii allow only cats and dogs.

For Hawaii-bound flights, pets in the baggage hold may be limited or not allowed at all, depending on what months you fly. And specific guidelines are in place due to the delicate ecosystem of the islands. For more information about pet health and documentation needed for arrival into Hawaii, visit If you don’t have the necessary documents ready upon arrival, your pet may be quarantined for up to 120 days.

American Airlines

Passengers traveling on American Airlines may be able to bring their cats or dogs on flights. You’ll have to book a reservation for your pet ahead of time (space is limited) by contacting the airline’s reservations department. All pets must be at least eight weeks old to fly within the U.S. and Puerto Rico.

Pets in cabin

When traveling with your pet in the aircraft cabin, its carrier replaces one of your carry-on items and must meet the airline’s size guidelines.

A total of seven kennels are permitted on American airline flights. Five total kennels are allowed on American Eagle flights with one kennel permitted in the first class cabin. Underseat storage in the first class and business cabins on some Boeing and Airbus aircraft may be too small to bring your carry-on pet.

Kennel guidelines for in-cabin travel on American Airlines

All pet carriers must be able to fit underneath the seat in front of you. If you’re traveling with your pet, American advises that you call 800-433-7300 ahead of time to verify under-seat dimensions.

Pets in cargo

With a health certificate and reservation for each pet, you can check-in up to two pets with American Airlines assuming they meet your destination’s standard health and age requirements. You may have two pets of the same species in one kennel, as long as they meet age, weight, and size restrictions.

Some Airbus aircrafts (A321, A321neo, A321S, A321H, A320, and A319) don’t permit checked pets; review your itinerary ahead of time to ensure your pet can be checked upon arrival. If you have questions, reach out to American directly or learn more about its pet travel policies.

Cost to fly with your pet on American Airlines

The fee for a checked pet is $200 per kennel, and $150 when traveling to and from Brazil. The cost to bring a pet in the aircraft cabin is $125 per kennel. Services animals aren’t charged, regardless of the destination or where they’re held.

Pet restrictions on American Airlines

Certain breed restrictions apply for the safety of your pet. Short-nosed cats and dogs aren’t accepted on American Airlines. In addition to breed restrictions, certain locations and routes have varying carry-on and checked pet restrictions, such as Australia, the Caribbean, Hawaii, Mexico, specific South American countries, and on transatlantic and transpacific travel.

Extreme temperature restrictions also apply. If any location on your flight itinerary is above 85 degrees Fahrenheit or below 45 degrees Fahrenheit, you’re not allowed to travel with a pet. Cold weather restrictions may be waived if you have a letter from a licensed vet confirming that your pet is accustomed to a specific cold weather temperature.

Delta Air Lines

To book a reservation for your pet on Delta Air Lines, contact 1-800-221-1212 to make arrangements ahead of your flight. Space for in-cabin pets is limited and some destinations (e.g. international) require passengers to ship pets via cargo.

Pets in cabin

Dogs and cats may travel in the cabin if they meet age and health requirements, and if your seat permits carry-on pets. Pet birds are only permitted inside the cabin on domestic U.S. flights, except when traveling to Hawaii, U.S. Virgin Islands, Puerto Rico, and Guam.

For Delta flights, pets are required to be at least 10 weeks old for domestic travel; at least 15 weeks old when traveling to the EU; and at least 16 weeks when traveling to other international destinations.

Typically, you can have only one pet per carrier. A couple exceptions apply, such as when your pet is traveling with an unweaned litter or if two pets of the same breed and size are in one carrier. In these circumstances, you’re charged for only one pet.

Kennel guidelines for in-cabin travel on Delta

In order to travel with your pet in-cabin on Delta, your pet’s carrier must fit under the seat in front of you. Contact Delta directly to verify under-seat dimensions before your trip.

Pets in cargo

To ship your pet to your final destination via Delta Cargo, you must make arrangements ahead of time and have a valid health certificate from a licensed vet.

On the day of your flight, you’ll need to drop off your pet to Delta Cargo check-in at least three hours before your departure time and sign a confirmation that you’ve offered your pet food and water within the past four hours. Keep in mind that there’s no guarantee that your pet will be on the same itinerary or plane as you.

For the safety of your pet, Delta doesn’t accept warm-blooded pets in cargo for flights that are longer than 12 hours.

All pets traveling into Hawaii require a health certificate dated within 14 days of arrival to your destination.

Pets in cabin

Dogs and cats are allowed as a carry-on when flying between the Hawaiian Islands. For flights departing from Hawaii to North America, only dogs and cats are permitted in the main cabin.

During the flight, you’re required to keep your pet inside its kennel and stow the carrier under the seat in front of you during taxi, takeoff, and landing.

Kennel guidelines for in-cabin travel on JetBlue

8 tips for keeping your pet safe and comfortable on a flight

Although planning your pet’s travel arrangements can feel complicated, making sure you’ve set your pet up for a successful trip can help ease your worries. Here are a few ways to keep their travel experience as comfortable as possible.

  1. Visit your vet beforehand to ensure they’re healthy enough to handle the stress of travel.
  2. Book direct flights to avoid excess time spent in their carrier.
  3. Choose an airline that lets your pet travel in-cabin.
  4. Avoid booking during extreme weather months, if possible. Make other accommodations if this is unavoidable.
  5. Trim your pet’s nails before the trip so they don’t snag while inside the carrier.
  6. Give your pet some exercise at home or at the airport’s designated pet area.
  7. Take your pet to go potty before departure to limit accidents during travel.
  8. Make sure your pet’s kennel is lined with enough absorbent material so your pet doesn’t have to lay on waste.

Pet airfare travel checklist: Things you need to bring

  • Vaccination records
  • A recently issued health certificate
  • Pet collar or harness, leash, and ID tag
  • Pet carrier that meets airline regulations
  • Food and water dish
  • Food and water
  • Treats for in-cabin companions
  • Potty accident items (e.g. paper towels, pet wipes, and a plastic bag for soiled carrier items)
  • Comfort items, such as a favorite toy or blanket, if permitted
  • A recent photo of your pet and their carrier

How to save on pet fees with the right credit card

Bringing your pet with you on your trip can make your travel experience that much more meaningful, but pet fees can be costly. Booking your pet’s arrangements using a travel rewards credit card that covers pet fees can help relieve you of some of the financial burden.

For example, The Platinum Card by American Express offers a $200 airline fee credit that covers incidentals such as pet travel fees. 

If you travel often, especially with your pet, having the right credit cards in your wallet can help you offset the cost of airlines’ pet fees.

The final word on flying with pets

Choosing the best airline for you and your pet depends on your destination, the airline’s restrictions, and the needs of your pet. Giving your pet a positive travel experience means doing your due diligence in planning ahead for a smooth ride. Always ensure that your pet is healthy enough to travel before you go, and enjoy your trip!
