Southwest Airlines no longer accepts ESA letters for air travel. All animals onboard must meet pet travel regulations.

Southwest Pet Policy:

Small cats and dogs only

Pet fee: $95 each way

Animals must remain in their carrier for the entire flight

Use of ESA Letter:

While it doesn’t apply to travel, an ESA letter may help during airport security screening if extra emotional support is needed.
