Southwest Airlines Pet Policy Essentials
Southwest allows small pets in carriers that fit on your lap or under the seat. Understanding size rules, documentation, and fare structure is essential when you select the best pet carrier for southwest airlines.
The airline requires pets to remain in the carrier at all times, with the carrier stowed under the seat in front of you. Soft-sided carriers are popular because they easily fit in tight spaces and can be carried onto the jet without extra hassle.
Size, Fit, and Airline Rules
Measured dimensions are critical when you choose a carrier for Southwest. Your fully contained carrier must fit within 18 x 14 x 8 inches to stay on your lap.
How to Measure Your Carrier
Use a tape to check interior length, width, and height. Include wheels and handles in the measurement, because Southwest staff will check the full assembled size at the gate.
Material Choices and Real-World Use
The best pet carrier for southwest airlines balances rugged construction with airline-friendly profiles. Different materials perform differently in heat, moisture, and impact scenarios.
Soft-Sided vs Wire vs Plastic
Soft-sided nylon carriers compress easily for overhead bins and under-seat storage. Wire and plastic cages offer more structure and better ventilation but can exceed size limits if frames are bulky.
