<p style="font-size: medium;" data-start="908" data-end="972">If you plan to bring your pet on a flight, it is important to understand the <strong data-start="1070" data-end="1151">southwest pet policy before departure. The airline permits small domestic cats and dogs that are at least eight weeks old and properly vaccinated to travel inside the cabin. Pets must remain inside a well-ventilated carrier that fits beneath the seat throughout the journey. Southwest Airlines limits the number of pet carriers allowed on each flight, and reservations are typically provided on a first-come, first-served basis. Passengers must also pay a standard pet travel fee for each one-way trip. Reviewing these guidelines in advance helps travelers ensure a safe and smooth journey with their furry companions.
