Quick Facts:
This pet carry on policy is ideal for travelers who want to keep their pet close throughout the flight.
Your pet must be placed in a soft- or hard-sided carrier that meets Southwest's size and ventilation requirements. Carriers must not exceed 18.5" x 8.5" x 13.5".
When it comes to the Southwest Airlines pet policy weight limit, there’s no fixed number stated, but the pet must be small enough to fit comfortably inside the carrier. Both the pet and the carrier should fit under the seat.
Tip from Tours N Travel Pro: Use a trial run at home—place your pet inside the carrier for a few hours before flying to ensure comfort.
Booking your pet is simple, but seats for pets are limited and offered on a first-come, first-served basis. Be sure to call ahead to confirm space availability.
Steps to book your pet:
Unlike other airlines, Southwest does not require a health certificate for pets, which is another reason the pet policy for Southwest Airlines is considered traveler-friendly.
