Understanding the Southwest Airlines Pet Policy: A Complete Guide for Pet Travelers

Traveling with pets can be stressful, but the Southwest Airlines Pet Policy is designed to make the experience as smooth and comfortable as possible for both pets and their owners. Whether you're flying for a vacation, a move, or a visit with family, Southwest allows small pets to travel in-cabin under specific conditions. This guide provides everything you need to know about Southwest’s pet policy, including rules, fees, carrier requirements, and helpful tips for a seamless journey.

What Pets Are Allowed on Southwest Airlines?

Under the Southwest Airlines Pet Policy, only small domestic cats and dogs are allowed to travel, and they must be vaccinated. Unlike some other airlines, Southwest does not allow exotic animals, birds, or any other pet types, and pets cannot travel in the cargo hold—only in-cabin.

This policy prioritizes the safety and comfort of animals by avoiding the risks associated with cargo travel, such as temperature changes, pressure issues, and mishandling.

In-Cabin Pet Travel Requirements

Here are the key in-cabin travel guidelines as outlined in the Southwest Airlines Pet Policy:

1. Carrier Rules
   Your pet must be in a leak-proof, well-ventilated carrier that fits under the seat in front of you. The pet must remain inside the carrier for the entire flight, including during takeoff, taxi, and landing.
    

2. Carrier Dimensions
   The maximum dimensions for soft-sided carriers are 18.5" long x 8.5" high x 13.5" wide. Southwest sells its own pet carriers online and at airport ticket counters to ensure compliance.
    

3. One Pet Carrier Per Passenger
   Only one pet carrier per ticketed passenger is allowed, and you can bring up to two pets in the same carrier, provided they are of the same species and can comfortably fit inside.
    

4. Age Requirement
   Pets must be at least 8 weeks old to travel. This ensures they are healthy and strong enough to handle the stress of flying.
    

Fees and Reservations

The pet fare under the Southwest Airlines Pet Policy is $125 one way. This fee is nonrefundable and separate from your ticket.

Important Notes:

• Pet reservations cannot be made online—you must call Southwest Airlines to add a pet to your booking.
   

• Space is limited, as only six pets are allowed per flight, so it’s best to reserve as early as possible.
   

• Pets are accepted on a first-come, first-served basis, and there's no waitlist.
   

Boarding and Check-In Process

When you arrive at the airport:

• Go to the ticket counter to check in your pet and pay the pet fare.
   

• You will receive a pet tag to attach to your carrier.
   

• Arrive at least 90 minutes early to allow enough time for pet check-in, especially if it’s your first time flying with your pet.
   

Once you're through security, pets must remain in the carrier at all times, even in the boarding area.

Seat Restrictions for Pet Travelers

There are some seating limitations for passengers traveling with pets:

• You cannot sit in an exit row.
   

• You cannot sit in a bulkhead seat, as there is no under-seat storage.
   

• If you're traveling with a pet and a child, you may be restricted from certain rows depending on FAA regulations.
   

Health and Vaccination Documentation

While Southwest Airlines does not require a health certificate for pets traveling domestically, pets must be in good health and properly vaccinated. You are responsible for meeting any state-specific travel regulations, especially if traveling to places like:

• Hawaii (where Southwest does not accept pets due to quarantine laws)
   

• Certain international destinations (where pets are not permitted on Southwest flights at all)
   

Always consult your vet and check local travel laws before flying.

Southwest Airlines Pet Policy vs. Other Airlines

Compared to other major U.S. carriers, the Southwest Airlines Pet Policy is relatively simple and straightforward. Here are a few points of comparison:

• No pets in cargo: While other airlines allow pets in checked baggage or cargo, Southwest only permits pets in the cabin, reducing stress and risks.
   

• Fixed, flat fee: Some airlines base pet fees on weight or distance, while Southwest keeps it at $125 each way.
   

• No breed restrictions: Many airlines have bans on specific dog breeds (like snub-nosed breeds), but Southwest has no breed-specific rules, as long as the pet meets size and carrier requirements.
   

Tips for a Smooth Flight with Your Pet

1. Book Early: With only six pets allowed per flight, reserve your spot early.
    

2. Choose Your Seat Wisely: Pick a seat with extra space if possible, and avoid restricted rows.
    

3. Get Your Pet Used to the Carrier: Before flying, help your pet get comfortable in their career at home.
    

4. Avoid Feeding Right Before the Flight: Feed your pet a few hours before boarding to prevent nausea or accidents.
    

5. Pack Essentials: Bring treats, a collapsible water bowl, and a small absorbent pad for the carrier.
    

6. Plan for Security Screening: You’ll have to remove your pet from the carrier during TSA screening, so bring a harness and leash for safety.
    

Traveling with Emotional Support or Service Animals

The Southwest Airlines Pet Policy has separate guidelines for service animals, which are allowed under the Air Carrier Access Act (ACAA). Emotional support animals, however, are no longer classified as service animals under DOT rules and must follow regular pet policy guidelines, including being in a carrier and paying the pet fare.

Service animals must be trained to perform a specific task related to a disability and may fly without charge, but documentation and advance notice may be required.

Final Thoughts: Is the Southwest Airlines Pet Policy Right for You?

If you’re looking to travel domestically with a small dog or cat, the Southwest Airlines Pet Policy offers a pet-friendly, safe, and straightforward way to bring your companion along. With affordable fares, no cargo pet travel, and a clear set of guidelines, Southwest is a solid choice for pet parents who prioritize safety and convenience.

Just remember to book early, follow all carrier size rules, and prepare your pet for the journey to ensure a pleasant experience for everyone on board.
