<p style="font-size: medium;" data-start="1326" data-end="2053">The southwest airlines in cabin pet policy allows passengers to travel with their small pets in the cabin under specific conditions. Cats and dogs must be at least eight weeks old and remain in a leak-proof, well-ventilated carrier throughout the flight. The carrier must fit under the seat in front of the passenger, and seating restrictions apply, as pets cannot be seated in exit rows or seats without under-seat stowage. A limited number of pets are allowed per flight, and the pet fee is charged for each direction. Understanding these rules and restrictions before traveling ensures a smooth and stress-free journey for both passengers and pets.
