Carrying pets can be stressful and most pet parents usually fear the restrictions imposed on weight, carrier restrictions and the hidden charges.

We will also unravel all the details you need to know about the pet policy of the Southwest Airlines in-cabin travel, carrier regulations, weight restriction, and the secrets of easy boarding in this guide.

What is the Southwest Airlines Pet Policy All About?

The Southwest Airlines pet policy is designed to make traveling with your furry friend straightforward. Unlike some carriers, Southwest does not allow pets in the cargo hold, which ensures that pets travel safely with you in the cabin.

The key rule to note is that Southwest has no fixed pet weight limit. Instead, your pet must be small enough to fit comfortably in an airline-approved carrier that goes under the seat in front of you. This means the carrier weight is included in the allowance, making it essential to choose a lightweight, comfortable carrier.
