The price of your pet's ticket is determined by the service you are purchasing, which also affects the Southwest Pet Fee for your pet. If you want your pet to travel with you, you must be able to show documentation of their shots and medical history. On our website, reservations can be made. Pets must be transported in containers that can fit under the seat of your vehicle, such as carriers, crates, or bags. If it complies with these specifications, you may also carry your pet's carrier into the cabin with you.
