Southwest Airlines Pet Policy for Beginners

Toggle1. Southwest Airlines Pet Policy Overview
Southwest Airlines offers a pet-friendly travel experience with certain guidelines to ensure that both passengers and pets are comfortable during the flight. Their pet policy allows small dogs and cats to fly with you in the cabin. However, Southwest does not allow pets to fly in the cargo hold, so your furry friend will need to be small enough to fit comfortably in an approved carrier under the seat in front of you.

1.1. Pet Eligibility
From my own personal experience, understanding the type of pet allowed is the first step. Southwest Airlines only accepts dogs and cats on board. Other types of animals such as reptiles, birds, or rodents are not permitted, even if they are service animals. This is an important point to note when booking your flight.
- Dogs and Cats: Southwest allows domesticated dogs and cats, and they must be at least 8 weeks old to travel.
- Service Animals: Southwest Airlines complies with the Americans with Disabilities Act (ADA), allowing service animals to travel with you in the cabin free of charge.
1.2. Pet Carrier Requirements
When traveling with pets, their carrier must meet specific size and design requirements to be allowed on board. From my own personal experience, I found that Southwest is quite clear about their pet carrier guidelines:
- Size Limitations: Your pet carrier must be small enough to fit under the seat in front of you. The maximum carrier dimensions are 18.5″ long x 8.5″ high x 13.5″ wide.
- Ventilation: The carrier must be well-ventilated. Make sure that your pet’s carrier has adequate ventilation on at least three sides, which will allow air to flow freely and keep your pet comfortable.
- Type of Carrier: Hard-sided or soft-sided carriers are acceptable, but it’s always a good idea to go for one that’s soft-sided as it can provide more flexibility in terms of fitting under the seat.

2. Pet Fees
One of the first questions that come to mind when flying with a pet is how much it will cost. Southwest Airlines charges a non-refundable fee of $95 each way for your pet to fly with you in the cabin. From my own personal experience, this fee is relatively reasonable compared to other airlines, and the value it provides, such as the comfort of knowing your pet is safe and by your side, is well worth it.
2.1. Payment and Booking
To book your pet’s spot, you will need to add your pet during the flight booking process. You cannot add a pet to your reservation via Southwest’s website once your flight is already booked, so make sure to call their customer service line or complete the pet reservation at the time of booking. There is a limit of six pets per flight on Southwest Airlines, so it’s crucial to book early, especially during peak travel seasons.
3. Booking a Flight for Your Pet
Booking your pet’s flight with Southwest is straightforward, but there are a few things to keep in mind to ensure the process goes smoothly.
3.1. Pet Reservation
As mentioned, you can reserve your pet’s seat (the spot for their carrier) either at the time of booking or by calling Southwest’s reservations team. It’s essential to book early, as only six pets are allowed in the cabin per flight, and those spaces fill up quickly, particularly on busy flights.
3.2. Types of Flights
From my own personal experience, flying with your pet is easiest on shorter flights. For long-haul flights, it’s important to consider how your pet will handle the journey. Flights that are over three hours long can be particularly challenging for pets, so make sure your pet is comfortable inside their carrier and has access to water if needed.
3.3. Arrival at the Airport
When you arrive at the airport, head to the ticket counter, where you’ll need to check in your pet. Southwest Airlines requires you to check in with your pet at the counter, no online check-ins for pets are allowed. The agent will confirm your pet’s reservation and ensure that their carrier meets the airline’s requirements. Be sure to allow some extra time at the airport for this check-in process.
4. Preparing for Your Flight
In preparation for your flight, it’s essential to take several factors into account to ensure your pet’s comfort and safety during the journey.
4.1. Before the Flight
- Exercise: Take your dog for a walk or a potty break before heading to the airport. This can help them burn off some energy and reduce anxiety during the flight.
- Food and Water: Avoid feeding your pet a large meal right before the flight to prevent discomfort. You can offer a light snack and a little water. Consider taking a travel water bowl or bottle to keep them hydrated.
- Pet Comfort Items: From my experience, pets tend to feel more secure when they have something familiar with them. A blanket, a favorite toy, or a t-shirt with your scent can provide comfort during the flight.
4.2. During the Flight
Once you’re on board, it’s time to relax and enjoy the flight. Southwest Airlines allows pets to travel under the seat in front of you. Your pet must remain in the carrier for the entire flight, so make sure they’re comfortable and familiar with their surroundings before takeoff.
- Comfort: Make sure your pet is in a comfortable position in their carrier. Avoid opening the carrier during the flight, as this can cause stress or make your pet feel unsafe.
- Calming Techniques: If your pet is particularly anxious, consult your vet about options for calming medication or sprays that may help keep them calm during the flight.
5. Tips and Pro-Tips for Traveling with Pets on Southwest Airlines
Now that you know the basics of Southwest Airlines’ pet policy, let’s dive into some helpful tips and pro-tips that will ensure your pet’s flight experience is as smooth as possible.
5.1. Pro-Tip: Get Your Pet Acclimated
Before flying, try to get your pet used to their carrier. From my own personal experience, I recommend taking your pet on short car trips with the carrier so that they become accustomed to it. The more relaxed your pet is in their carrier, the smoother the flight will be.
5.2. Pro-Tip: Choose the Right Flight Time
If possible, choose a flight time that aligns with your pet’s routine. Some pets do better on flights when they’re not hungry or overly energetic. Flying at a time that fits your pet’s natural schedule can make a big difference.
5.3. Pro-Tip: Book Your Pet Early
Since Southwest Airlines allows only six pets per flight, make sure to book early. As soon as you know you’ll be traveling with a pet, book the flight and reserve your pet’s spot right away.
5.4. Pro-Tip: Pack Pet Essentials
Make sure you have all the pet essentials packed for the journey, including:
- Pet waste bags
- A travel water bottle
- Treats or toys
- A comfort blanket or familiar item
5.5. Pro-Tip: Check for Any Health Restrictions
If your pet is elderly or has any medical conditions, make sure to consult with your vet before flying. Southwest Airlines has certain health restrictions, especially if your pet has specific medical conditions or is pregnant. Always check these restrictions in advance.

6. Southwest Airlines Pet Policy: FAQ
Here are some frequently asked questions that might help clarify any doubts you may have:
6.1. Can I take my pet as checked luggage?
No, Southwest Airlines does not allow pets to travel as checked luggage or in the cargo hold. Your pet must travel in the cabin with you.
6.2. Can I take multiple pets on the same flight?
Each passenger can only take one pet in the cabin. If you have more than one pet, you’ll need to book additional seats or make arrangements for another person to accompany you with their pet.
6.3. What happens if my pet doesn’t fit in the carrier?
If your pet doesn’t fit comfortably in the carrier, they will not be allowed to travel in the cabin. Make sure your pet fits securely and comfortably in their carrier to avoid any issues at the airport.
Let me continue with more detailed insights to ensure your journey with Southwest Airlines and your pet goes as smoothly as possible. I’ll dive deeper into some additional helpful information, along with even more pro-tips for navigating your pet’s travel experience.
7. Pet Travel and Comfort: Key Considerations for Your Furry Friend
When flying with your pet, the goal is to make them feel as comfortable and safe as possible during the entire journey. While it’s easy to focus on the logistics of Southwest’s pet policy, ensuring your pet’s well-being before, during, and after the flight is just as important. Here are some more considerations to keep in mind for a pleasant travel experience.
7.1. Pre-Flight Preparation for Your Pet’s Comfort
From my own personal experience, the days leading up to your flight are just as critical as the flight itself. Setting up your pet for a stress-free experience begins well before you even reach the airport.
- Visit the Veterinarian: It’s always a good idea to check in with your vet before traveling. Make sure your pet is healthy and up to date on their vaccinations. If you’re flying internationally, be sure to check the pet health requirements for the country you’re visiting. Your vet can also advise you on whether any calming medications or natural remedies might be helpful for your pet during the flight.
- Routine: Stick to your pet’s normal routine as much as possible in the days leading up to your flight. A sudden change in their environment or schedule can cause anxiety. Regular walks, meals, and playtime can keep them calm and comfortable.
- Familiarize Your Pet with the Carrier: As I mentioned earlier, your pet needs to be comfortable in their carrier before the flight. To help them adjust, leave the carrier out in a space they use often, such as the living room or bedroom, and encourage them to explore it by placing treats or toys inside. The more they associate the carrier with positive experiences, the less likely they will be stressed during the flight.
7.2. In the Days Leading Up to Your Flight
There’s a lot to think about as your departure date approaches. Here are some final checks to ensure that you and your pet are fully prepared.
- Exercise: It’s important to give your pet a good walk or run before the flight, particularly if it’s a long flight. This helps to burn off any excess energy and reduce anxiety, which can make a big difference in how they handle the journey.
- Pet Identification: Accidents happen, so it’s always wise to ensure your pet has proper identification, like a collar with your contact information and a microchip, just in case you get separated.
- Food and Water Considerations: Avoid feeding your pet right before the flight to reduce the risk of nausea. I’ve found that offering a small meal several hours before departure works best. Be sure to carry a portable water bottle and collapsible bowl so your pet can stay hydrated during the trip.
8. What to Expect at the Airport
The airport experience with your pet can be one of the more stressful parts of the journey, especially if you’re unsure of what to expect. From my own personal experience, I can tell you that arriving prepared can alleviate much of the stress that comes with navigating through the airport.
8.1. Check-in Process
As mentioned earlier, pets must be checked in at the ticket counter, there is no online check-in option for pets. When you arrive at the counter, you will need to:
- Confirm your pet’s reservation (remember, only six pets are allowed in the cabin on each flight).
- Show your pet’s health certificate if required (especially for international flights).
- Pay the pet fee, which is $95 per way.
Once you’ve checked in your pet, you’ll head through security just like any other passenger. The security process for pets can vary from airport to airport, but generally, here’s what to expect:
- You will need to take your pet out of the carrier and carry them through the metal detector. The carrier itself will go through the x-ray machine.
- Be sure to keep your pet in your arms at all times and maintain control. Some airports have special pet relief areas after security, so take advantage of these to give your pet a bathroom break before the flight.
8.2. Pet Relief Areas
Southwest Airlines allows you to bring your pet through security, but there’s one thing I’ve learned through personal experience, finding a designated pet relief area after passing through security is a game-changer. Many airports offer pet relief stations, which are usually located after security near the gates. These areas are equipped with synthetic grass and waste bags so that pets can relieve themselves before boarding the flight.
If your pet is particularly nervous or has to wait in the terminal, these areas provide them with the chance to relax and ease their anxiety.
8.3. Arrival at the Gate
Once you’ve cleared security, head to your gate as usual. There’s no special waiting area for pets, so your pet will be with you in the terminal. I’ve found that sitting in a quieter part of the terminal before boarding can help your pet feel more relaxed. It can also be beneficial to keep your pet inside their carrier until boarding time.
9. During the Flight: Your Pet’s Experience
Once you’re on the plane, the experience becomes more predictable. Here’s what you can expect and what you can do to keep your pet comfortable during the flight.
9.1. Under the Seat
Pets must remain in their carriers under the seat for the entire flight. The carrier must fit entirely under the seat, with no part of the carrier extending into the aisle or blocking any emergency exits.
I’ve found that it’s important to keep the carrier in front of you as much as possible, as it provides your pet with a sense of security, knowing you’re close by. Don’t open the carrier during the flight, as this can lead to stress for both you and your pet.
9.2. Calming Your Pet
Some pets may get anxious during the flight, especially if it’s their first time traveling. I’ve found that offering calming treats or sprays (available at pet stores) before the flight can help. For longer flights, you may want to ask your vet about medications that can help reduce anxiety without making your pet too drowsy.
9.3. Frequent Updates
Although Southwest doesn’t allow you to open the carrier during the flight, you can still talk to your pet softly to help them feel calm. Pets are highly attuned to their owners’ voices, so hearing you can reassure them during the flight.
10. Post-Flight: What Happens After You Land
Once you’ve landed at your destination, there are a few things to keep in mind for a smooth transition.
10.1. Picking Up Your Pet
Since Southwest Airlines doesn’t transport pets as checked luggage, your pet will be with you for the entire flight. However, when you exit the plane, make sure to take extra care when opening the carrier and allowing your pet to exit. Airports can be overwhelming for pets with all the new smells and sounds, so it’s a good idea to carry your pet until you’re in a quieter area.
10.2. Pet Relief Areas
Once you’ve disembarked, look for a pet relief area before heading to baggage claim or your next destination. Your pet may need to relieve themselves after the flight, and these designated areas provide a safe and comfortable space for your pet to go potty.

11. Additional Tips: Dealing with Issues and Emergencies
No one wants to think about problems or emergencies while traveling, but being prepared can save you a lot of stress. Here are some tips to handle potential issues during your flight:
- Lost or Missing Pets: While Southwest Airlines has a strong reputation for safe travel, accidents can still happen. Make sure your pet is microchipped and has a collar with updated identification. If your pet is lost, immediately contact airport staff or Southwest personnel to initiate a search.
- Pet Illness: If your pet seems unwell or shows signs of distress, contact the flight attendants immediately. Southwest Airlines takes pet health seriously, and they will do what they can to ensure your pet is comfortable.
- Allergies: If you have an allergy to pets or are concerned about sitting near someone with a pet allergy, be sure to notify Southwest when booking your pet’s travel. While they try to accommodate these requests, seating availability is limited.
In Summary:
Traveling with your pet on Southwest Airlines is relatively simple as long as you follow their pet policy and prepare in advance. From my own personal experience, I can tell you that being well-prepared will make the whole process feel much easier and less stressful. With a little extra planning, you and your pet can enjoy the trip without any hassle.
