Southwest Pet Policy Guide: Rules, Fees, and Tips 2026
Traveling with pets can feel overwhelming, especially when airline rules differ widely. If you're planning a trip and searching for clarity on the southwest pet policy, this guide will help you understand everything in a simple, practical way. At the jersey flights, we believe travel should be smooth for both you and your furry companion, and knowing the rules in advance makes all the difference.
The southwest pet policy is known for being relatively straightforward compared to other airlines. Southwest Airlines allows small, vaccinated domestic cats and dogs to travel with passengers in the cabin under specific conditions. However, there are limitations you should be aware of before booking.
Only small cats and dogs are allowed in the cabin
Pets must remain inside an airline-approved carrier
The carrier counts as either your carry-on or personal item
A limited number of pets are allowed per flight
Unlike some airlines, Southwest does not allow pets to travel in the cargo hold. This makes it a safer and more comfortable option for many pet owners.
Your pet must fit comfortably inside a carrier that can be placed under the seat in front of you. The carrier must be:
Well-ventilated
Leak-proof
Securely enclosed
Soft-sided carriers are generally preferred because they are easier to fit under seats. Make sure your pet has enough space to move slightly but not excessively.
Southwest charges a pet fee per carrier, per flight. This fee is non-refundable and must be paid at the airport ticket counter. It’s important to arrive early, as pet spots are limited and assigned on a first-come, first-served basis.
If you're already planning your trip with southwest vacation packages, it’s smart to factor in the pet fee and availability when scheduling your flights.
While Southwest does not always require a health certificate for pets, some states may have their own regulations. It's best to:
Check destination state requirements
Carry vaccination records
Ensure your pet is healthy and calm
Pets showing signs of aggressive behavior or illness may be denied boarding.
Once onboard, your pet must:
Remain inside the carrier at all times
Be stowed under the seat
Not disturb other passengers
Flight attendants may check to ensure compliance, so following these rules is essential for a hassle-free journey.
Travel plans can change unexpectedly. If you experience a southwest airline missed flight, your pet reservation does not automatically transfer. You may need to:
Rebook your flight
Pay the pet fee again
Confirm pet availability on the new flight
Planning ahead and arriving early can help you avoid such complications.
Here are some practical tips to make the journey easier for your pet:
Avoid feeding your pet right before the flight
Take them for a walk prior to boarding
Use familiar bedding inside the carrier
Keep them calm with reassurance
At the jersey flights, we often recommend doing a short practice trip with your pet in the carrier to reduce anxiety.
While your pet won’t be using the internet, you might want to stay connected. Southwest airlines wifi is available on most flights, allowing you to browse, work, or stay entertained while keeping an eye on your pet.
If you're managing your travel budget, checking your southwest gift card balance before booking can help offset costs like pet fees or seat upgrades. It’s a simple step that can make your trip more affordable.

The policy allows small dogs and cats in approved carriers inside the cabin, provided they remain under the seat and meet size and behavior requirements.
The pet fee is charged per carrier, per flight, and must be paid at the airport. It is non-refundable and separate from your ticket fare.
Pet reservations are handled separately from vacation packages, so you must confirm availability directly with the airline even if you book a package.
You will need to rebook both your flight and pet reservation, as pet spots do not automatically transfer to new flights.
WiFi is available on most flights and can be used normally while your pet stays safely under the seat in front of you.
You can check your balance online through the airline’s official website before applying it to your booking.
Coupon codes may be available during promotions and can help reduce overall travel costs, though they typically apply to tickets rather than pet fees.
