What Southwest Airlines says about emotional support animals
Southwest Airlines treats emotional support animals (ESAs) as passengers who require an animal’s presence for a documented emotional or psychological disability. This overview describes policies, requirements, seating, travel options, and common misconceptions. It also explains how rules differ between domestic U.S. flights and international arrivals or departures. Key points include advance notice, behavior expectations, and cabin placement. For the latest details, always confirm directly with Southwest before booking or flying.
Definitions used by Southwest for ESAs
Service animal vs emotional support animal
Under current U.S. regulations, Southwest defines service animals as dogs individually trained to perform tasks related to a disability. Emotional support animals provide comfort through presence but do not perform trained tasks. Both may travel in the cabin at no charge when documentation is provided, yet the rules and required paperwork differ.
ESA documentation
Acceptable documentation typically includes a letter from a licensed mental health professional stating you have a diagnosed mental or emotional disability and that the animal provides necessary support. Some travelers also provide proof of current treatment or medication. Keep copies with you and be ready to present them to airline agents if requested. Note: Southwest does not require a specific form, but documentation must be recent and clearly link the animal to your disability.
How Southwest handles ESAs on board
Seating and behavior expectations
ESAs are expected to remain on the passenger’s lap or in a carrier that fits under the seat, unless larger space is allowed based on the animal’s size and behavior. Animals must be leashed or harnessed when outside the carrier. You may be moved or denied boarding if the animal cannot be secured safely or behaves disruptively. Any disruptive or aggressive behavior can result in removal from the flight.
Health, safety, and relief areas
On long flights, Southwest recommends planning for the animal’s needs. Relief areas are limited on aircraft; carriers should be sized so the animal can stand, turn, and lie down comfortably. Feeding and watering should be timed to reduce the need for in-flight relief. Extended flights may have operational constraints, so discuss needs with a reservation agent in advance.

|---|---|---|
| Advance notice for ESAs | Recommended at booking and at check-in; required for some international operations | Southwest policy documentation and agent guidance |
| Documentation accepted | Recent mental health professional letter linking disability to the need for an ESA | Southwest customer service statements |
| In-cabin placement | On passenger’s lap or in an approved carrier that fits under the seat | Southwest operations guidance |
| Charges for ESAs | No separate pet fee for ESAs that meet documentation and behavior rules on domestic flights | Southwest fare rules and customer service |
| International variations | Rules can differ by country; some require quarantine or additional health documentation | Southwest international operations and partner airline policies |
Domestic U.S. flights: what to expect
For travel within the United States, Southwest generally permits ESAs in the cabin when valid documentation is provided and the animal is under control. You must communicate the need for an ESA when making a reservation and reconfirm at check-in. The animal must remain in a carrier or on your lap during boarding, taxi, takeoff, landing, and turbulence. Be prepared to show documentation at the gate if requested. Remember that rules may change, and international segments can have additional requirements.
International travel and arrival considerations
International flights may involve different documentation, quarantine rules, or health certificates for both passengers and animals. Some countries require advance notice of an ESA, specific formats for documentation, or additional approvals. If you are flying to or from another country, verify requirements with Southwest and the relevant authorities well before departure. Service dogs may have streamlined access in some regions, but ESAs often follow the pet entry rules of the destination.
How Southwest policies compare with common myths
- Myth: Any pet can be an ESA on Southwest. Fact: Only ESAs with proper documentation and that meet behavior standards are allowed in the cabin.
- Myth: ESAs can occupy a separate seat. Fact: ESAs must be contained on the passenger’s lap or in a carrier that fits under the seat.
- Myth: Southwest charges a pet fee for ESAs. Fact: No fee is charged for qualifying ESAs on most domestic flights, provided they follow rules.
- Myth: ESAs are treated exactly like service dogs everywhere. Fact: Service dogs have broader access rights; ESAs are permitted in the cabin but follow specific documentation and behavior rules.
Practical steps when booking and checking in
Contact Southwest as early as possible to confirm current ESA requirements, especially for international travel. Provide documentation when requested and arrive at the airport with ample time. Check in again at the gate if required, and be ready to present your professional letter. Pack familiar items, feeding schedules, and any health records for the animal. These steps reduce last-minute issues and help ensure a smooth travel experience.
When policies can change and how to stay informed
Airline policies evolve due to regulations, operational needs, and partner agreements. International rules, in particular, can shift with local laws and health requirements. To stay current, check Southwest’s official website, review notifications after booking, and speak with a reservation agent if your circumstances change. If you rely on an ESA for travel, confirm details each time you plan a trip and keep documentation up to date.
