Step 1: Discovering the Current Southwest Pet Fee (Engage Here!)
Hey there, fellow pet parent! Before we go any further, tell me, what kind of pet are you planning to bring along? Is it a playful pup or a curious cat? Knowing this will help us tailor our advice even more!
Now for the direct answer: As of July 2025, Southwest Airlines charges a non-refundable pet fare of $125 per pet carrier, each way, for flights within the U.S. Mainland.
However, there's a special rate for flights between Hawaiian Islands, where the fee is significantly lower at $35 per pet carrier, each way.
Important Note: Pet fares are subject to change, so always check the official Southwest Airlines website or call them directly for the most up-to-date pricing before you book.
This fee covers the transportation of your pet in the cabin, provided they meet all the necessary requirements. Now let's explore those requirements!
Step 2: Understanding Southwest's Pet Eligibility and Restrictions
Not all pets are created equal when it comes to air travel. Southwest has specific rules about which animals can fly and under what conditions.
2.1 Allowed Animals
Southwest Airlines exclusively permits small, vaccinated domestic cats and dogs to travel in the cabin. Unfortunately, no other animal species are allowed.
2.2 Age Requirements
Your furry traveler must be at least eight (8) weeks old to travel on a Southwest flight. This ensures they are mature enough to handle the stress of air travel.
2.3 Destination Limitations
This is a crucial point for pet owners:
Southwest does not accept pets on flights to or from Hawaii (the mainland U.S. to Hawaii or vice versa).
Pets are also not allowed on international itineraries.
However, pets are accepted on flights between Hawaiian Islands.
For customers traveling to Puerto Rico, specific requirements may apply, so always check in advance.
2.4 Unaccompanied Minors
Tip: Share one insight from this post with a friend.
Unaccompanied Minors cannot travel with a pet. A ticketed adult must accompany the pet and be responsible for it.
2.5 Per Passenger Limits
You are allowed one pet carrier per ticketed Customer. Each pet carrier can contain no more than two of the same species of small cat or dog, provided they fit comfortably and can stand up and turn around in the carrier.
Step 3: Carrier Requirements – Size, Safety, and Comfort
Your pet's comfort and safety, and the ability to stow the carrier, are paramount. Southwest has strict guidelines for pet carriers.
3.1 Dimensions
The maximum dimensions for pet carriers that can be stowed under the seat in front of you are:
18.5" (L) x 13.5" (W) x 9.5" (H)
3.2 Carrier Type and Features
Carriers can be soft-sided or hard-sided.
They must be leak-proof to prevent any messes.
They must be well-ventilated on at least three sides (for domestic travel).
Your pet must be able to stand up and turn around comfortably inside the carrier. No part of your pet should extend out of the carrier.
The carrier needs secure fasteners (heavy-duty zippers are recommended for soft-sided carriers).
3.3 Carrier Counts as Carry-on
Your pet carrier will count as either your personal item or your regular carry-on bag. This means you can board the aircraft with either:
A pet carrier and a personal item.
A pet carrier and a regular-sized carry-on bag.
Step 4: Booking Your Pet's Ticket – The Right Way
You can't simply add your pet to your online reservation. There's a specific process to ensure space is available.
4.1 Limited Space
Southwest Airlines typically allows a limited number of pet carriers per scheduled flight (usually up to five or six, excluding service animals, though this can vary). This space is offered on a first-come, first-served basis. This makes early booking for your pet critical.
4.2 How to Book
To make a reservation for your pet, you must call Southwest Airlines directly. Do not try to add them online.
Call 1-800-I-FLY-SWA (1-800-435-9792).
A Customer Representative will gladly assist you in creating a booking for your pet.
It's highly recommended to call as soon as your travel plans are confirmed to secure a spot for your furry friend.

4.3 Payment
The pet fare must be paid at the airport ticket counter on the day of travel using accepted credit cards. While you book the pet over the phone, the payment happens in person.
Step 5: Day of Travel: Airport and Onboard Experience
Knowing what to expect at the airport and during the flight will help reduce stress for both you and your pet.
5.1 Airport Check-in
You are required to check in with a Customer Service Agent at the ticket counter or departure gate counter.
The pet fare will be paid at this time.
You should arrive at the airport at least 30 minutes before the normal check-in times for your flight to allow ample time for the pet check-in process.
5.2 Security Checkpoint
At the security checkpoint, you will need to hold your pet and walk through the screening device while the pet carrier is X-rayed.
All pet carriers are subject to being searched.
5.3 Gate Area and Boarding
Pets must be secured in their pet carrier at all times while in the gate area, during boarding/deplaning, and for the entire flight. Failure to follow this requirement may result in your pet being denied transportation.
Customers traveling with pets will board with their assigned boarding group.
5.4 Onboard the Aircraft
Your pet carrier must be stowed under the seat in front of you for taxi, takeoff, and landing, and for the entire duration of the flight.
You cannot sit in an emergency exit row seat or a seat with no under-seat stowage in front of them when traveling with a pet.
Your pet must remain inside its carrier at all times while onboard the aircraft.
A pet that shows disruptive behavior (e.g., excessive barking, scratching, growling, biting, urinating/defecating) may be denied boarding or removed from the flight.
5.5 Pet Relief Areas
Southwest generally provides information about pet relief areas at each of the locations they serve. Plan ahead to utilize these before and after your flight. Keep in mind that the airline will not "hold" a flight for you to take your pet to a relief area.
Step 6: Special Considerations and Tips for a Smooth Trip
Traveling can be stressful, especially for pets. Here are some extra tips to make the journey as comfortable as possible.
6.1 Acclimatization
It's a fantastic idea to introduce your pet to their carrier several weeks before your flight. Let them get used to being inside it, associating it with positive experiences. This can significantly reduce anxiety on travel day.
6.2 Hydration and Feeding
Consult your veterinarian about feeding your pet before travel. Some vets recommend a light meal a few hours before, while others suggest withholding food to prevent an upset stomach. Always offer water before and after the flight. Do not sedate your pet without explicit veterinary guidance, as it can pose health risks at altitude.
QuickTip: Look for lists — they simplify complex points.
6.3 Veterinary Consultation
Before any travel, especially air travel, it is highly advisable to consult with your veterinarian. They can assess your pet's health, discuss any potential risks, and provide guidance on stress reduction. While Southwest doesn't require a health certificate for domestic pet travel, some states or territories might, so always check state-specific requirements.
6.4 Identification
Ensure your pet has proper identification, including a collar with your contact information and microchip details.
6.5 Prepare for Delays
Travel can be unpredictable. Have a plan for potential delays, including extra food, water, and waste bags for your pet.
Step 7: Understanding the Difference: Pets vs. Service Animals
It's important to distinguish between pets and trained service animals, as their policies differ significantly.
7.1 Service Animals
Southwest Airlines welcomes fully trained service dogs that are individually trained to perform tasks for the benefit of a qualified individual with a disability.
Dogs are the only trained service animals accepted.
They are not subject to pet fees or carrier requirements.
Specific U.S. Department of Transportation Service Animal Air Transportation forms are required and must be presented at the ticket counter or gate.
Service animals must be harnessed, leashed, or otherwise tethered to you at all times and trained to behave.
7.2 Emotional Support Animals (ESAs)
As of January 11, 2021, the U.S. Department of Transportation (DOT) no longer considers emotional support animals as service animals. This means Southwest Airlines treats emotional support animals as pets, and they are subject to all the standard pet policies and fees, including the pet fare and carrier requirements.
