Pet-Friendly Airlines

If your ideal getaway includes your four-legged co-pilot, you're not alone. More and more pet parents are choosing to bring their pets along for the ride — and thankfully, a growing number of airlines are welcoming them in the cabin.

Whether you're hopping across states or crossing continents, it’s important to know which carriers make pet travel a breeze and what to expect before you board.

In the U.S., several major airlines allow pets to travel in the cabin, though the rules (and fees) can vary. Here's a quick look at some of the most pet-friendly domestic options:

• Delta Air Lines – Permits dogs, cats, and household birds in the cabin, provided they remain in a carrier.

• American Airlines – Allows up to two small cats or dogs per passenger, as long as they’re at least eight weeks old and fit comfortably under the seat in front of you.

• United Airlines – Permits in-cabin pets on any flight operated by United or United Express, depending on the destination’s pet policies.

• Southwest Airlines – Welcomes small, vaccinated dogs and cats, though pets aren’t allowed on international flights or to Hawaii.

• JetBlue – Allows up to six pets per flight; your pet and carrier must weigh 20 pounds or less combined.

• Spirit Airlines – Allows up to two pets in one carrier, but only one carrier per passenger. Pets must stay inside the carrier for the entire journey.

• Alaska Airlines – Travelers 18 and older can bring a pet onboard as long as they’re not seated in an emergency exit row.

If you're planning a transatlantic adventure with your pet, there are several European airlines that also allow pets in the cabin. Here are some options and their weight limits for pets in carrier:

• Air France, KLM, Lufthansa, SWISS, Iberia, Finnair, TAP Air Portugal, Turkish Airlines, Air Europa – up to 8kg (about 17.6 lbs)

• ITA Airways, NEO – up to 10kg (about 22 lbs)

• Air Europa – up to 8kg

Before booking, there are a few important things to keep in mind. Always review the airline’s carrier guidelines — your pet must fit comfortably under the seat in a soft-sided carrier, and only certified service animals are exempt. It’s best to book your flight directly with the airline when traveling with a pet to avoid miscommunications or missed requirements. Also, remember that breed restrictions, destination rules, and cabin class limitations can all impact whether your pet can come along.

Lastly, make sure your pet is healthy, well-behaved, and fully documented before takeoff. Airlines can deny boarding if your pet appears distressed or if paperwork isn’t in order — and nobody wants a travel hiccup that could have been avoided. Traveling with your pet may take a little extra planning, but it’s so worth it. With the right airline and a little preparation, your next great adventure can be one you both enjoy!
