Southwest Airlines Pet Policy: Emotional Support & Service Animals 2026 Guide

Traveling with your beloved animal companion can be a source of comfort and support, especially for those who rely on emotional support animals (ESAs) or service animals. Understanding each airline's specific policies is crucial for a smooth and stress-free journey. This comprehensive guide will walk you through Southwest Airlines' pet policy for 2026, focusing on the distinctions and requirements for both emotional support animals and service animals.

Understanding the Key Distinctions: ESA vs. Service Animal

Before diving into Southwest's specifics, it's vital to clarify the difference between emotional support animals and service animals, as their treatment under airline regulations is significantly different.

• Service Animals: These are dogs (or in some cases, miniature horses) individually trained to do work or perform tasks for the benefit of an individual with a disability. The task(s) must be directly related to the individual's disability. Under the Air Carrier Access Act (ACAA) as revised by the U.S. Department of Transportation (DOT), service animals are generally permitted to fly in the cabin free of charge.
• Emotional Support Animals (ESAs): While ESAs provide comfort and support, they are not trained to perform specific tasks related to a disability. As of January 2021, the DOT no longer considers ESAs as service animals. Consequently, most airlines, including Southwest, now treat ESAs as standard pets.

Southwest Airlines' Current Policy (2026)

Service Animals on Southwest Airlines

Southwest Airlines welcomes trained service animals in the cabin with their owners, provided they meet the DOT's definition and requirements. Here's what you need to know:

• DOT Service Animal Air Transportation Form: Passengers traveling with a service animal are required to complete and submit the U.S. Department of Transportation Service Animal Air Transportation Form. This form attests to the animal's health, training, and behavior. It's highly recommended to complete this form in advance.
• Behavior and Control: Service animals must be well-behaved and under the control of their handler at all times. They must not pose a direct threat to the health or safety of others or cause significant disruption in the cabin.
• Placement: The service animal must be able to fit in the space at the passenger's feet or lap without encroaching on another passenger's space or blocking the aisle. If the animal is too large, alternative arrangements may need to be made, potentially requiring the purchase of an additional seat or travel in the cargo hold.
• Number of Animals: A passenger with a disability may travel with up to two service animals.

Emotional Support Animals (ESAs) on Southwest Airlines

As per current regulations, Emotional Support Animals are now transported as pets. This means:

• Pet Carrier Requirements: Your ESA must travel 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.
• Pet Fees: A pet fare will apply for each one-way trip. These fees are subject to change, so always check Southwest's official website for the most current pricing.
• Limited Space: Southwest limits the number of pets allowed per flight. It's crucial to make reservations for your pet well in advance.
• Health Documentation: While not always explicitly required for in-cabin pets, having up-to-date vaccination records and a health certificate from your veterinarian is always a good practice.

Booking and Check-in Process

To ensure a smooth experience, follow these steps:

1. Notify Southwest: When booking your flight, indicate that you will be traveling with a service animal or a pet. For service animals, be prepared to submit the DOT form. For pets, ensure there's space available on your desired flight.
2. Arrive Early: Arrive at the airport well in advance of your flight. This allows ample time for check-in, any necessary paperwork verification, and security screening.
3. Designated Relief Areas: Familiarize yourself with the airport's designated animal relief areas before your flight.

Tips for a Smooth Journey

• Preparation is Key: Ensure your animal is comfortable with travel, crowds, and new environments.
• Leash and Harness: Service animals must be leashed or harnessed at all times in the airport and on the aircraft.
• Comfort Items: Bring a favorite toy or blanket for your pet (if traveling as a pet) to help them feel secure.
• Food and Water: Pack a small amount of food and a collapsible water bowl. Offer water before boarding to keep them hydrated.
• Potty Breaks: Plan for potty breaks before and after your flight.

Common Questions (FAQs)

Q: Can my ESA fly in the cabin for free on Southwest?
A: No, as of 2026, ESAs are generally treated as pets and require a pet fare and must travel in an approved carrier under the seat.

Q: Do I need a vest or special tag for my service animal?
A: While not legally required by the DOT, a vest or harness identifying your animal as a service animal can help prevent misunderstandings and facilitate your journey.

Q: What if my service animal is too large to fit at my feet?
A: You may need to purchase an additional seat, or in some rare cases, the animal may need to travel in the cargo hold if no other arrangements can be made. Contact Southwest directly to discuss options for larger service animals.

Q: Are there breed restrictions for pets on Southwest?
A: Southwest generally does not have breed restrictions for in-cabin pets, but the animal must fit comfortably in an approved carrier under the seat.

Conclusion

Traveling with your emotional support or service animal on Southwest Airlines requires careful planning and adherence to their policies. By understanding the distinctions between ESAs and service animals, completing necessary documentation, and preparing for your journey, you can ensure a comfortable and compliant travel experience for both you and your animal companion.
