Traveling with pets has become increasingly common, especially as more people consider dogs part of the family. Whether you are relocating, taking a vacation, or flying for an emergency, understanding an airline’s pet policy is essential before booking a ticket. One of the most common questions travelers ask is: “Can I bring my dog on Frontier flight?”
The short answer is yes — Frontier Airlines allows small dogs to travel in the cabin on most domestic flights. However, there are important rules regarding carrier size, fees, health requirements, and breed restrictions that passengers must understand before arriving at the airport.
This detailed guide explains Frontier Airlines’ pet policy, cabin requirements, costs, restrictions, travel tips, and step-by-step instructions for flying safely with your dog.
Frontier Airlines Pet Policy Overview

Unlike some major airlines, Frontier does not transport pets as checked baggage or cargo. This means dogs can only travel in the cabin with their owners.

Dogs Commonly Allowed
The airline generally permits:

Dogs That May Be Restricted
Frontier may refuse transportation if a dog:

Certain international destinations may also impose additional restrictions based on local animal import laws.
Does Frontier Allow Large Dogs?

This is one of the biggest limitations travelers should know before booking.
If your dog cannot comfortably fit inside an airline-approved carrier under the seat, the dog will likely not be permitted onboard.
Alternatives for Large Dog Owners
Travelers with larger dogs often consider:
- Pet-friendly road trips
- Airlines with cargo pet programs
- Professional pet transport services
- Relocation specialists
Because Frontier is an ultra-low-cost carrier, its pet accommodations are more limited compared to some full-service airlines.
Frontier Airlines Pet Carrier Requirements
One of the most important aspects of flying with a dog is choosing the correct carrier.
Approved Carrier Features
Your carrier should:
- Be leak-proof
- Provide ventilation
- Fit under the seat
- Allow the dog to stand and turn around
- Remain fully closed during the flight
Soft-sided carriers are usually recommended because they are easier to fit beneath airline seats.
Frontier Pet Carrier Size
Based on publicly available airline guidance, acceptable dimensions are generally around:
- 18 inches long
- 14 inches wide
- 8 inches high
However, aircraft types vary, so travelers should always verify updated measurements before departure.
How Much Does Frontier Charge for Dogs?
Frontier charges a pet transportation fee for each direction traveled.
Estimated Frontier Pet Fee
| Flight Type | Estimated Fee |
| Domestic Flights | Usually around $99 each way |
| International Routes | May vary |
Airline fees can change at any time. Travelers should confirm current pricing during booking.
Important Note About Fees
Pet fees are typically:
- Non-refundable
- Charged per flight direction
- Separate from baggage fees
Because Frontier operates with an à la carte pricing model, additional charges may apply for seat selection or carry-on luggage.
How to Add a Dog to Your Frontier Reservation
Adding a dog to your reservation is usually straightforward.
Step-by-Step Instructions
1: Book Your Flight Early
Pet space onboard is limited.
Booking early increases the chance that your dog will be accepted.
2: Add Your Pet During Booking
Frontier may allow pet additions:
- Online
- Through customer support
- Via airport assistance

Measure your carrier carefully before departure.
4: Arrive Early at the Airport

Can Dogs Fly Internationally on Frontier?
Frontier allows pets on select international routes, but regulations vary significantly by country.
International Travel Challenges
Many countries require:
- Rabies vaccination records
- Veterinary health certificates
- Microchips
- Import permits
- Quarantine procedures
For example, countries like the United Kingdom maintain strict pet entry regulations.
Before international travel, passengers should review:
- Government import rules

Failure to comply may result in denied boarding or pet quarantine.
Health Requirements for Flying With a Dog
Although Frontier may not always require a health certificate for domestic travel, veterinary experts strongly recommend a pre-flight checkup.
Important Health Considerations
Dogs should:
- Be hydrated
- Be calm enough for travel
- Have updated vaccinations
- Avoid flying when ill
Brachycephalic (Short-Nosed) Dogs
Flat-faced breeds such as:
- Bulldogs
- Pugs
- Boston Terriers
may face greater respiratory risks during travel.
Veterinarians often advise extra caution with these breeds due to breathing sensitivity.
According to veterinary research published through PubMed and guidance from animal welfare experts, stress and heat can increase respiratory complications in brachycephalic dogs.
Can Puppies Fly on Frontier Airlines?
Yes, puppies may fly if they meet minimum age requirements.
Most airlines require puppies to be at least 8 weeks old, though some destinations impose stricter standards.
Before Flying With a Puppy
Ensure the puppy:
- Has completed early vaccinations
- Can remain calm in a carrier
- Is healthy enough for travel
Very young puppies may experience anxiety, dehydration, or motion stress more easily than adult dogs.
Service Dogs on Frontier Flights
Frontier permits trained service dogs accompanying qualified individuals with disabilities.
Service Dog Rules
Passengers may need to submit:
- U.S. Department of Transportation forms
- Behavioral attestations

This change aligns with updated U.S. Department of Transportation regulations.
As a result:

What Happens if My Dog Barks or Misbehaves?
Airlines can deny boarding or remove disruptive animals.
Common Reasons for Refusal

Frequent Errors
Wrong Carrier Size
One of the top reasons pets are rejected.
Waiting Too Long to Add a Pet

Missing Health Documents
International travelers especially should double-check paperwork.

Factors That Improve Safety
