Southwest Airlines Pet Policy: Navigating ESA & Service Animals in 2026

Traveling with your beloved animal companion can be a source of comfort and support, especially for individuals relying on emotional support animals (ESAs) or service animals. As of 2026, understanding airline policies is crucial for a smooth journey. This comprehensive guide will walk you through Southwest Airlines' current pet policy, focusing on the distinctions and requirements for both emotional support animals and service animals.

Understanding the Landscape: ESA vs. Service Animal

Before delving into Southwest's specifics, it's vital to differentiate between Emotional Support Animals (ESAs) and Service Animals (SAs). The U.S. Department of Transportation (DOT) updated its regulations in 2021, significantly impacting how airlines accommodate these animals.

• Service Animals (SAs): These are dogs, regardless of breed or type, that are individually trained to do work or perform tasks for the benefit of a qualified individual with a disability. This work or task must be directly related to the individual’s disability. Service animals are permitted to fly in the cabin with their handlers free of charge.
• Emotional Support Animals (ESAs): Following the DOT's 2021 ruling, airlines are no longer required to recognize ESAs as service animals. This means ESAs are generally treated as pets and must adhere to the airline's standard pet policy, which often includes fees and specific carrier requirements.

Southwest Airlines' Current Pet Policy for 2026

Southwest Airlines, like many carriers, has adapted its policies to align with the DOT's updated regulations. Here's what you need to know:

Service Animals on Southwest Airlines

Southwest Airlines welcomes trained service dogs that assist Customers with disabilities. To travel with a service animal, you will generally need to:

• Complete the U.S. Department of Transportation Service Animal Air Transportation Form: This form attests to the animal's health, training, and behavior. It must be submitted to Southwest Airlines prior to your flight.
• Provide proof of training: While not always explicitly required at check-in, airlines may ask for verbal assurance or visual cues of the animal's training.
• Ensure the animal is under your control: The service animal must be harnessed, leashed, or tethered at all times and fit within your foot space without encroaching on another passenger's space.
• Behavioral Standards: Service animals must be well-behaved and not pose a direct threat to the health or safety of others. Disruptive behavior may result in the animal being denied boarding.

Emotional Support Animals (ESAs) on Southwest Airlines

As of 2026, Emotional Support Animals are no longer recognized as service animals by Southwest Airlines. If you wish to travel with an ESA, it must meet Southwest's pet policy requirements:

• Pets in Cabin: Small vaccinated domestic dogs and cats are permitted to travel in the cabin with their owners.
• Pet Carrier Requirements: Your pet must be in an approved pet carrier that fits under the seat in front of you. The carrier counts as either your one carryon item or your one personal item.
• Fees: A pet fare will apply for each one-way trip.
• Reservations: Pet travel space is limited per flight, so it's crucial to make reservations for your pet in advance.

Tips for Traveling with Your Animal Companion on Southwest

To ensure a stress-free travel experience, consider these tips:

• Book Early: Especially for pets, space is limited. Book your flight and your animal's spot as far in advance as possible.
• Prepare Documentation: Have all necessary forms (DOT Service Animal Form, vaccination records for pets) readily accessible.
• Potty Breaks: Allow your animal ample opportunity to relieve themselves before boarding.
• Comfort Items: Bring familiar toys or blankets to help your animal feel secure during the flight.
• Hydration: Offer water before and after the flight, but be mindful during the flight to avoid accidents.
