Are you planning a trip with your pet?

Whether you have a tiny Chihuahua or a stout French Bulldog, Southwest Airlines makes flying with pets stress-free and straightforward.

This complete guide explains everything about the Southwest Airlines pet policy, from cabin rules to carrier size to their all-breed acceptance approach. If you're unsure how to travel with your pet on Southwest, Tours N Travel Pro is always here to assist.

What Makes the Pet Policy for Southwest Airlines Unique?

Unlike some carriers that impose breed bans or limit pet types, the pet policy for Southwest Airlines is refreshingly inclusive. Your pet can and must fit the size and health standard; however, any dog or cat can be admitted—there is no breed restriction.

Practice Highlights of the Policy:

1. Allowed pets: Cats and dogs, only small.

2. Type of travel (only in-cabin, no cargo movement).

3. Restriction of breed: None! Any breeds are allowed.

4. Pet fare: each way, per pet carrier, is 125.

Your furry friend can either be a Pomeranian or a Boston Terrier, but at Southwest Airlines, it does not matter, as they will practically embrace any breed at all. A huge sigh of relief to the pet parent who has had their breed discriminated against at other airlines.

Southwest Airlines Pet Policy In Cabin: What You Need to Know

The Southwest Airlines pet policy in cabin ensures that pets travel alongside their owners, never in cargo. This reduces stress and ensures safety for animals and owners alike.

In-Cabin Travel Rules:

1. Pets must remain in their carrier under the seat in front of you.

2. Your pet carrier counts as one carry-on item.

3. You’re allowed one pet carrier per passenger.

4. Only domestic U.S. flights accept pets—international travel is not permitted for pets.

Example: If you’re flying from Orlando to Denver, you can take your small dog with you in the cabin, provided they stay inside an airline-approved carrier under your seat.

Southwest Airlines Pet Carry-On Policy: Carrier Dimensions & Requirements

If you're flying with your pet, you'll need to follow the Southwest Airlines pet carry on policy carefully.

Carrier Requirements:

1. Max dimensions: 18.5” L x 13.5” W x 8.5” H

2. The carrier must be leak-proof and well-ventilated

3. Your pet should be able to stand, turn around, and lie down comfortably.

Southwest sells its soft-sided carrier at select airport counters, but any airline-approved carrier meeting these specs is allowed.

Are There Any Southwest Airlines Pet Policy Weight Limits?

This is one of the best parts: the Southwest Airlines pet policy weight limit is not defined by pounds. That’s right—there’s no fixed pet weight limit. Instead, the policy focuses on whether your pet can fit comfortably in the carrier under the seat.

This makes the airline a top choice for travelers with pets that are small but slightly heavier, like compact and muscular breeds.

Booking a Pet on Southwest: Step-by-Step Guide

Booking your pet’s flight is simple:

1. Book your ticket as you normally would.

2. Call 1-800-435-9792 to add a pet reservation.

3. Pay the $125 pet fee in person at the ticket counter on the day of your flight.

Reminder: Southwest only accepts a limited number of pets per flight—usually six total pet carriers—so book early.

Why All Breeds Are Welcome: Southwest’s Inclusive Policy

One of the most appreciated aspects of the Southwest Airlines pet policy is its no-breed-restriction stance. While some airlines exclude certain dog breeds, especially short-nosed ones (like Pugs or Shih Tzus), Southwest focuses on safety, size, and behavior, not breed stereotypes.

As long as your pet:

1. Fits in the approved carrier.

2. Appears healthy.

3. Shows no aggressive behavior.

This fair, inclusive policy sets Southwest apart and makes it a pet-parent favorite.

Tips for a Smooth Journey with Southwest and Your Pet

1. Arrive Early: Get to the airport at least 90 minutes before your flight.

2. Get Comfortable: Let your pet explore the carrier in advance.

3. Avoid Feeding Right Before the Flight: This helps avoid motion sickness.

4. Stay Calm: Pets pick up on your energy—keep things light and happy!
