When flying with a pet on a Southwest flight, passengers must pay a $95 pet fare fee per carrier, each way. This additional expense is worth considering as you plan out your trip costs. This fee is refundable if you decide not to travel with your pet, you decide to cancel the flight or your flight is canceled.

Additionally, Southwest Airlines has a weight limit of 20 pounds per pet, including the carrier. If your pet and their carrier weigh more than 20 pounds, they will not be allowed to travel in the cabin and must be transported as cargo instead.
