Southwest Airlines Pet Policy: Your Guide to ESAs & Service Animals in 2026

Traveling with your beloved emotional support animal (ESA) or service animal can be a source of anxiety for many pet owners. Understanding each airline's specific policies is crucial for a smooth journey. At Clinical Support Animals (CSA), we're dedicated to providing clarity and support for individuals seeking certified emotional support and service animal documentation. This comprehensive guide will walk you through Southwest Airlines' policies for ESAs and service animals in 2026.

Understanding Southwest Airlines' Stance on Emotional Support Animals (ESAs)

As of January 11, 2021, the U.S. Department of Transportation (DOT) revised its Air Carrier Access Act (ACAA) regulations regarding emotional support animals. Under these new rules, airlines are no longer required to recognize emotional support animals as service animals. This means that emotional support animals are now generally treated as pets by most airlines, including Southwest.

What this means for your ESA on Southwest:

• Pets in Cabin: If your ESA is a small dog or cat, it may be able to travel in the cabin as a pet, provided it meets Southwest's pet carrier requirements and you pay the applicable pet fee. There are limitations on the number of pets allowed per flight, so it's essential to book early.
• Cargo Travel: Larger ESAs that do not fit under the seat in a carrier would need to travel as cargo, if permitted by Southwest's cargo policies and weather restrictions. However, Southwest does not typically transport animals in cargo.
• No Special Accommodations: Unlike service animals, ESAs are not granted special accommodations regarding cabin travel outside of standard pet policies.

It's vital to check Southwest Airlines' official website or contact their customer service directly for the most up-to-date pet policies and fees before making travel plans.

Service Animals on Southwest Airlines: What You Need to Know

The DOT's revised ACAA regulations continue to protect the rights of individuals with disabilities traveling with legitimate service animals. A service animal is defined as a dog, regardless of breed or type, that is individually trained to do work or perform tasks for the benefit of a qualified individual with a disability, including a physical, sensory, psychiatric, intellectual, or other mental disability.

Southwest Airlines' policy for service animals:

• Allowed in Cabin: Fully trained service dogs are permitted to fly in the cabin with their handlers, free of charge, provided they can be accommodated at the handler's feet or lap without encroaching on another passenger's space or blocking the aisle.
• DOT Service Animal Air Transportation Form: Southwest Airlines requires passengers traveling with a service animal to complete and submit the U.S. Department of Transportation Service Animal Air Transportation Form. This form attests to the animal's training, health, and behavior. It's highly recommended to complete this form in advance of your flight.
• Behavior and Control: Service animals must be under the control of their handler at all times, either by leash, harness, or other tether. They must also be housebroken and behave appropriately in public settings. Animals that display aggressive behavior or are disruptive may be denied boarding.
• Number of Service Animals: A passenger with a disability may travel with up to two service animals.
