The southwest pet policy in cabin is ideal for travelers with small pets who prefer in-cabin travel over cargo options. Since Southwest does not transport pets in cargo, the policy works best for cats and dogs that can comfortably fit in approved carriers. The airline’s straightforward rules, reasonable fees, and focus on pet safety make planning easier for pet owners. Although route and seating restrictions apply, many travelers appreciate the simplicity of the policy. If your pet meets all eligibility requirements, Southwest Airlines can be a convenient and pet-friendly travel choice.
