Best Airlines for Pets in 2026

Planning a trip with your cat involves much more than booking a ticket. Every airline has its own pet policies, fees, carrier requirements, and restrictions, all of which can affect your travel experience. While some airlines make flying with pets relatively simple, others may have more limitations depending on your destination or aircraft.

If you're searching for the best airlines for pets in 2026, it's important to look beyond price alone. Cabin travel options, pet fees, reservation policies, and overall customer experience all play a role in finding the right airline for you and your feline companion. Here's how some of the most popular U.S. airlines compare.

What Makes an Airline Pet Friendly?

Before comparing airlines, it's helpful to know what separates a truly pet-friendly airline from the rest. The best airlines make it easy for pets to travel safely in the cabin, provide clear guidelines for pet owners, and have straightforward booking processes. Affordable pet fees are certainly a bonus, but comfort and convenience often matter just as much.

When evaluating airlines, consider factors like whether pets are allowed in the cabin, how much the airline charges per flight, carrier size requirements, the number of pets allowed on each flight, and the airline's reputation for customer service. Choosing the airline that best fits your cat's personality and travel needs can make the entire journey less stressful.

JetBlue

JetBlue continues to rank among the best airlines for pet travel thanks to its straightforward in-cabin pet program and pet-friendly reputation. Cats can travel in the cabin as long as they're inside an airline-approved carrier that fits beneath the seat in front of you. The booking process is relatively simple, although pet reservations should be made early since only a limited number of pets are allowed on each flight.

Many travelers appreciate JetBlue's customer service and comfortable cabin experience, making it a popular choice for first-time pet travelers. While the airline does charge a pet fee, many cat owners feel the convenience and overall experience make it worthwhile.

Alaska Airlines

Alaska Airlines has long been considered one of the most pet-friendly airlines in the United States. The airline allows cats to travel in the cabin on many routes and is often praised for its flexible pet policies and knowledgeable staff. Its pet fees are generally competitive compared to other major airlines, making it an attractive option for budget-conscious travelers.

Because Alaska has extensive service along the West Coast and throughout Alaska, it's an especially good option for travelers in those regions. As with any airline, checking aircraft restrictions and reserving your pet's spot early is recommended.

American Airlines

American Airlines allows cats to travel in the cabin on many domestic flights, provided they remain inside an approved carrier for the duration of the trip. While the airline serves an extensive network of destinations, pet policies may vary depending on your route and aircraft type, so reviewing the requirements before booking is important.

For travelers who frequently fly American Airlines for business or vacation, bringing a cat can be a convenient option as long as you're familiar with the airline's guidelines and reserve your pet's space in advance.

Delta Air Lines

Delta offers in-cabin pet travel for cats on many domestic flights and some international routes, depending on destination requirements. The airline is often recognized for its reliability and broad route network, making it a convenient choice for travelers who need flexible scheduling.

Like other major airlines, Delta requires pets to remain inside an approved carrier that fits beneath the seat. Because destination regulations can vary, especially for international travel, it's worth reviewing any additional documentation requirements well before your departure date.

Southwest Airlines

Southwest Airlines remains a favorite among many pet parents because of its relatively affordable pet fee and simple pet travel policies. Cats are permitted to travel in the cabin on eligible domestic flights, and the airline's straightforward booking process makes it easy to add your pet reservation.

One limitation is that Southwest doesn't operate international flights, so it's best suited for travelers staying within the United States. If you're planning a domestic getaway with your cat, Southwest is often one of the more budget-friendly options available.

Which Airline Is the Most Affordable?

If keeping costs low is your top priority, Southwest and Alaska Airlines are often among the more affordable choices for flying with pets. While pet fees vary by airline and can change over time, these carriers have historically offered competitive pricing compared to some larger airlines.

That said, the lowest pet fee doesn't always translate to the best overall experience. Flight availability, customer service, convenient routes, and cabin comfort are all worth considering when deciding which airline offers the best value for your trip.

Preparing for Your Flight

No matter which airline you choose, a little preparation can go a long way toward making travel more comfortable for both you and your cat. Giving your cat time to adjust to their carrier before departure, booking nonstop flights when possible, and arriving at the airport early can all help reduce stress on travel day.

It's also a good idea to pack a few travel essentials in case of delays or long layovers. Along with food, water, treats, and cleaning supplies, having a portable litter option can make a big difference if your travel day doesn't go exactly as planned. If you'd rather have everything in one place, Roaming Whiskers' The Purr-Fect Start Car Travel & Emergency Preparedness Bundle includes travel essentials designed specifically for cats on the go, including Travel Gravel, a lightweight, travel-friendly litter that's easy to use in airport pet relief rooms, hotel stays, or other unexpected stops along your journey.

Which Airline Is Best for Traveling with Cats?

The best airline for your cat ultimately depends on your travel priorities. If customer experience and a pet-friendly reputation are at the top of your list, JetBlue and Alaska Airlines are excellent choices. Travelers looking for lower pet fees may find Southwest especially appealing, while American Airlines and Delta offer extensive route networks that make it easier to reach a wider range of destinations.

No matter which airline you choose, the key to a successful trip is preparation. Understanding your airline's pet policies, reserving your cat's space early, and packing the right travel essentials can help create a smoother, more comfortable experience from check-in to landing. By comparing your options ahead of time, you'll be better equipped to choose the airline that best fits both your travel plans and your cat's needs.
