When transporting a pet by a commercial airline, it is extremely important to understand their pet policy. These policies vary between airlines. Some allow small pets to fly in the cabin and others don’t. It is important to know the answers to all your questions before making your decision to fly your pet on any commercial airline. Can my pet fly in the cabin on Spirit Airlines? How much does it cost to fly a dog or cat on Spirit Airlines? What documents will I need? What are the carrier or crate requirements for Spirit Airlines? All your answers related to Spirit Airlines pet policy are answered below.
Note: It is important to mention that the pet policy of the airline that operates your pet’s route will preside over the policy of the airline that owns the route. This is important to note because if the operating airline changes during your trip, then you will likely need to claim and recheck your pet on the next airline. This will cause you to clear customs and enter the layover country. You will need time and extra documentation to accommodate this process during the layover unless flying domestically.
Are you planning a trip and wondering, “Can I bring my dog on Spirit Airlines?” Good news! Spirit Airlines does allow dogs and other small pets to travel in the cabin on domestic flights But before you pack your pup’s favorite toys, there are some important rules and requirements you need to know
As a pet parent who’s flown with my dog several times I know firsthand that airline pet policies can be confusing. So I’ve put together this comprehensive guide to help you navigate Spirit Airlines’ pet policy with ease.
Which Pets Are Allowed on Spirit Airlines?
Spirit Airlines permits the following pets in the cabin:
- Domestic dogs
- Domestic cats
- Small household birds (except to/from Puerto Rico and U.S. Virgin Islands)
- Small domestic rabbits (except to/from Puerto Rico and U.S. Virgin Islands)
It’s important to note that Spirit Airlines only allows pets on domestic flights, including Puerto Rico and St. Thomas, US.VI. Unfortunately, if you’re planning an international adventure, you’ll need to make other arrangements for your furry friend as Spirit doesn’t accept pets on international routes.
Pet Carrier Requirements
When traveling with your dog on Spirit Airlines, your pet must be kept in an approved carrier throughout the entire journey. Here are the carrier requirements:
- The carrier dimensions must not exceed 18″ x 14″ x 9″ (45.72cm x 35.56cm x 22.86cm)
- Only soft-sided carriers are permitted in the cabin
- The carrier must fit under the seat in front of you
- Your pet must be able to stand up and turn around comfortably inside the carrier
- Carriers that allow the pet’s head to remain outside are not allowed
- You can have a maximum of 2 pets in one carrier
- Only one carrier per passenger is permitted
The combined weight of your pet and carrier cannot exceed 40 pounds. This is an important consideration, especially if you have a medium-sized dog.
Booking and Fees
Spirit charges a pet fee per carrier (not per pet), per one-way flight. To find the current fee, you’ll need to visit Spirit’s website or contact their customer service. The fee is subject to change, so always check for the most up-to-date information before booking.
To add a pet to your reservation, you’ll need to chat with Spirit Airlines through their website. While advance notice isn’t required, it’s highly recommended because Spirit only allows a maximum of six pet containers on each flight. Don’t risk showing up at the airport only to find out that the pet quota has been reached!
Check-in Process with a Pet
When traveling with your dog, you must check in at the ticket counter. Self-service or curbside check-in is not available for passengers traveling with pets. Make sure to arrive extra early – I’d recommend at least 2 hours before domestic departures – to allow time for the check-in process.
During check-in, airline staff will inspect your pet carrier to ensure it meets all requirements. Your pet will also need to go through security screening, where you’ll need to remove your pet from the carrier so it can be X-rayed.
Required Documentation
For most domestic flights, Spirit Airlines doesn’t require a health certificate for pets traveling in the cabin. However, there are exceptions:
- For flights to Puerto Rico: A valid rabies vaccination certificate is required
- For flights to U.S. Virgin Islands: A health certificate is required
Even when not required, it’s always a good idea to bring along your pet’s vaccination records and health certificate, just in case. Better safe than sorry!
Seating Restrictions
When traveling with your pet on Spirit Airlines, you can sit almost anywhere you want, with two important exceptions:
- You cannot sit in the first row
- You cannot sit in emergency exit rows
This is because your pet carrier must be stowed under the seat in front of you during takeoff and landing.
Important Pet Requirements
Spirit Airlines has some additional requirements for pets traveling in the cabin:
- Your pet must be at least 8 weeks old and fully weaned
- Your pet must be harmless, inoffensive, and odorless
- Your pet cannot require any attention during the flight
- Your pet must remain in the carrier for the entire duration of the flight
- Your pet cannot be ill, violent, or in physical distress
If your pet becomes disruptive or causes a disturbance before departure, you and your pet may be denied boarding. It’s crucial that your dog is comfortable with being in a carrier for several hours.
Special Considerations for Brachycephalic (Snub-nosed) Dogs
If you have a brachycephalic or snub-nosed dog breed like a Bulldog, Pug, or Boston Terrier, Spirit Airlines notes that these breeds may be more vulnerable to risks during air travel. While they’re not prohibited, the airline recommends consulting with your veterinarian before flying with these breeds to discuss any special precautions.
Preparing Your Dog for Air Travel
Preparation is key to ensuring a smooth flight experience for both you and your dog. Here are some tips based on my experience:
-
Acclimate your dog to the carrier – Weeks before your flight, get your dog used to spending time in the carrier. Make it a positive experience by placing treats and toys inside.
-
Exercise before the flight – Take your dog for a long walk before heading to the airport to help them burn off energy.
-
Limit food and water – Feed your dog about 4 hours before the flight to prevent accidents, but ensure they stay hydrated up until a couple hours before departure.
-
Pack comfort items – Include a familiar blanket or toy in the carrier to provide comfort during the journey.
-
Consider calming aids – Talk to your vet about natural calming aids or, if necessary, mild sedatives for extremely anxious dogs.
-
Plan for bathroom breaks – Take your dog to a pet relief area at the airport before boarding.
What If My Dog Doesn’t Qualify for Cabin Travel?
Unfortunately, if your dog doesn’t meet the requirements for cabin travel (for example, if they’re too large), you’ll need to make alternative arrangements. Spirit Airlines does not transport pets in cargo at any time.
Your options may include:
- Choosing a different airline that accommodates larger pets
- Using a pet shipping service
- Driving to your destination instead
- Leaving your pet with a trusted pet sitter or boarding facility
My Personal Experience Flying with My Dog on Spirit
Last summer, I flew from Chicago to Fort Lauderdale with my small Yorkie, Max. The process was smoother than I expected, but I’m glad I prepared in advance.
I purchased a soft-sided carrier that fit Spirit’s dimensions and spent a month getting Max comfortable with it. On the day of the flight, I arrived at the airport 2.5 hours early, which gave us plenty of time for check-in and a visit to the pet relief area.
The Spirit staff were friendly and efficient during check-in. During the flight, Max mostly slept in his carrier under the seat in front of me. I had a window seat, which I found gave us a bit more privacy.
Final Thoughts
Traveling with your dog on Spirit Airlines is definitely possible with the right preparation. The airline’s pet policy allows for small pets to join you in the cabin, as long as they meet all the requirements.
Remember that your pet’s comfort and safety should be your top priority. If your dog gets anxious easily or doesn’t do well in confined spaces, air travel might not be the best option. Always consider what’s best for your furry friend.
By following Spirit’s guidelines and preparing adequately, you and your dog can have a stress-free journey to your destination. Happy travels to you and your four-legged companion!

Service dog pet policy
All service dogs may fly in the cabin at no charge. They must be trained by a person or organization that specializes in service dog training to provide specific tasks for a person with a disability including a physical, sensory, psychiatric, intellectual, or other mental disability. Spirit may asked whether the service dog is needed to provide assistance for a disability.
Up to two service dogs can fly per passenger. If there is not adequate room for your service dog(s), passengers can purchase an additional seat next to them for this purpose.
Service dogs must be suitably marked, harnessed and leashed. They must fit in the passenger’s lap if small enough or the space provided at their passenger’s feet without interfering with cabin operations or other passengers. They will not be seated in exit rows. They must be clean, mannerly and not show any signs of aggression toward other passengers or the flight crew.
Notice must be provided to the airline at least 48 hours prior to departure. A Department of Transportation form and a Relief Attestation Form must be completed and submitted to Spirit’s Guest Care Department at least 48 hours prior to departure. These forms can be completed at check in, and the passenger should allow extra time to do that. All required documentation required for the destination country must also be provided at check in.
All service dogs are subject to the same requirements as regular dogs when traveling internationally.
