Spirit Airlines Pet Policy Overview
Spirit Airlines permits small domesticated dogs in the cabin on many flights within the United States. Cats, small household birds, and rabbits are also permitted in some cases.
However, Spirit has several limitations designed to protect passenger safety and animal welfare.
Key Highlights of Spirit’s Pet Policy

|---|---|
| Pets Allowed in Cabin | Yes |
| Pets Allowed in Cargo | No |
| Allowed Animals | Small dogs, cats, rabbits, household birds |
| International Pet Travel | Limited |
| Pet Fee | Charged each way |
| Carrier Required | Yes |
| Maximum Pets Per Passenger | Usually 2 |
| Service Dogs Allowed | Yes |
| Emotional Support Animals | No longer treated as service animals |
According to the official airline policy, pets must remain inside an approved carrier for the entire flight except in limited circumstances.
What Types of Dogs Are Allowed on Spirit Flights?
Spirit Airlines generally accepts small domestic dogs that can safely fit inside an airline-approved pet carrier placed under the seat in front of you.
Dogs Typically Allowed
The following are commonly accepted:
- Small companion dogs
- Toy breeds
- Puppies meeting age requirements
- Small mixed breeds
Examples include:
- Chihuahua
- Pomeranian
- Maltese
- Yorkshire Terrier
- Shih Tzu

Dogs That May Face Restrictions
Spirit may deny boarding if the dog:
- Appears aggressive
- Shows signs of illness
- Has difficulty breathing
- Cannot comfortably remain in the carrier

Flat-faced breeds (brachycephalic breeds) may require extra caution because of respiratory concerns during travel. Veterinary experts, including organizations like the American Veterinary Medical Association, advise owners to carefully assess air travel risks for short-nosed dogs.
Examples include:
- Bulldogs
- Pugs
- Boston Terriers
- French Bulldogs
Can Large Dogs Fly on Spirit Airlines?
No. Spirit Airlines does not transport large dogs in cargo.
Because Spirit only allows pets inside the passenger cabin, your dog must fit comfortably inside a carrier that fits under the seat.
If your dog is too large for cabin travel, you may need to consider another airline with cargo pet transportation options.
Based on publicly available information, there is no confirmed data on Spirit Airlines offering checked pet cargo services.
Spirit Airlines Pet Carrier Requirements
One of the most important aspects of flying with your dog is choosing the correct carrier.
Spirit Approved Pet Carrier Dimensions
Spirit Airlines states that pet carriers must fit underneath the seat.
Typical maximum dimensions are approximately:
| Dimension | Maximum Size |
|---|---|
| Length | 18 inches |
| Width | 14 inches |
| Height | 9 inches |
Soft-sided carriers are generally recommended because they fit more easily under airline seats.
Carrier Rules
Your carrier must:
- Be leak-proof
- Be well ventilated
- Fully enclose the pet
- Allow the dog to stand and turn around
- Remain closed during the flight
Recommended Carrier Features
Look for carriers with:
- Mesh ventilation panels
- Soft padded bottoms
- Waterproof lining
- Secure zippers
- Seatbelt compatibility
Travel experts from Consumer Reports recommend testing carriers several weeks before travel so pets can become familiar with them.
How Much Does Spirit Charge for Dogs?
Spirit Airlines charges a pet fee for each flight segment.
Spirit Pet Fee
| Route Type | Estimated Fee |
|---|---|
| Domestic Flight | Around $125 each way |
Fees can change over time, so travelers should verify current pricing directly with:
Spirit Airlines Pet Travel Information
Important Notes About Pet Fees
- Fees are non-refundable in many cases
- Pet fees are separate from baggage fees
- Fees apply per carrier, not necessarily per pet
- Additional taxes may apply
How to Add Your Dog to a Spirit Reservation
Adding your dog to your reservation is relatively simple, but availability is limited because airlines cap the number of pets allowed onboard.
Step-by-Step Instructions
1: Book Your Flight Early
Pet spots are limited on each aircraft.
Reserve early to improve your chances.
2: Contact Spirit Airlines
After booking, add your pet reservation through:
- Spirit customer support
- Online account management
- Airport reservation desk
3: Confirm Pet Availability
Spirit limits the total number of pets per flight.
Do not assume your pet is confirmed until you receive approval.
4: Pay the Pet Fee
The fee is usually collected during reservation updates or airport check-in.
5: Prepare Documentation
Bring any required health or vaccination records.
Health Certificate Requirements for Dogs
Health documentation requirements vary depending on your destination.
Domestic U.S. Flights
For many domestic routes, Spirit may not require a health certificate, but some states do.
Travelers should verify rules with:
- Destination state authorities
- Local agriculture departments
- Veterinarians
International Travel
International pet travel is more complicated and may involve:
- Rabies vaccination proof
- USDA paperwork
- Import permits
- Microchip documentation
- Quarantine requirements
The Centers for Disease Control and Prevention (CDC) maintains updated rules regarding dogs entering the United States.
Vaccination Requirements
Most airlines strongly recommend up-to-date vaccinations.
Commonly required vaccines include:
| Vaccine | Purpose |
|---|---|
| Rabies | Legal requirement in many regions |
| DHPP | Protects against major canine diseases |
| Bordetella | Kennel cough prevention |
The American Kennel Club recommends discussing travel vaccination timing with your veterinarian before flying.
Service Dogs on Spirit Airlines
Service dogs are treated differently from pets under federal law.
Spirit Airlines Service Dog Policy
Under rules enforced by the U.S. Department of Transportation, trained service dogs assisting passengers with disabilities are generally permitted without standard pet fees.
Requirements for Service Dogs
Passengers may need to:
- Submit DOT service animal forms
- Confirm training standards
- Ensure the dog behaves appropriately
- Keep the dog harnessed or leashed
Service animals must fit safely within the passenger’s foot space.
Emotional Support Animals: Important Changes
Many travelers are confused about emotional support animals (ESAs).
Are Emotional Support Dogs Allowed for Free?
No.
In recent years, U.S. airline regulations changed significantly.
The U.S. Department of Transportation no longer requires airlines to recognize emotional support animals as service animals.
As a result:
- ESAs are treated as pets
- Standard pet fees apply
- Carrier requirements still apply
This rule change was implemented to improve consistency and safety in air travel.
Preparing Your Dog for Air Travel
