If you’re flying soon with your four-legged companion, this updated guide will walk you through each step — clearly and simply.

Overview of Sun Country Airlines Pet Policy

Traveling with a pet is not just about transportation — it’s about carrying a member of your family along with you. Sun Country Airlines understands that your dog or cat is more than just an animal. That’s why the airline has created clear and structured pet travel guidelines to help make the journey smooth, safe, and comfortable for both you and your furry companion.

Sun Country Airlines allows small dogs and cats to travel inside the aircraft cabin on domestic flights within the United States. This means your pet can stay close to you during the journey, safely secured inside an approved carrier that fits under the seat in front of you. Many travelers prefer this option because it reduces stress for pets and provides peace of mind for owners.

For larger pets that cannot fit under the seat, cargo transportation may be available on select routes. When offered, cargo services are designed to prioritize animal safety, with temperature controls and handling procedures that follow aviation standards. However, availability depends on route, aircraft type, and weather conditions.

There are a few important things to remember:

• Pets are allowed only on domestic U.S. flights
  
• International pet travel is currently not permitted
  
• Each flight has a limited number of pet spots
  
• Early reservation is strongly recommended to secure space
  

Because pet capacity is limited, it’s always a good idea to contact the airline as soon as you book your ticket. Waiting until the last minute may result in no available pet slots, even if seats are still open for passengers.

Sun Country Airlines also follows strict health, safety, and temperature guidelines to protect animals during travel. In cases of extreme heat or cold, cargo pet services may be restricted to prevent health risks. These precautions are taken to ensure your pet’s well-being throughout the journey.

By understanding the rules in advance and preparing properly, you can turn what might feel stressful into a comfortable and well-organized travel experience for both you and your pet.

Does Sun Country Airlines Allow Pets?

Yes, Sun Country Airlines understands that pets are family, and they do allow certain animals to travel with you. If you’re planning a trip and don’t want to leave your furry companion behind, the airline provides a few safe and structured options.

Here’s what is permitted:

✔ Small cats and dogs in the cabin – If your pet is small enough to fit comfortably inside an approved carrier under the seat in front of you, they can travel right there with you. This option gives pet parents peace of mind since their companion stays nearby throughout the flight.

✔ Larger dogs and cats via cargo (select routes only) – For pets that are too large for cabin travel, cargo transportation may be available depending on the route, aircraft type, and weather conditions. This service follows safety guidelines to ensure animals are handled carefully and transported securely.

✔ Trained service animals – Passengers with disabilities can travel with trained service dogs at no additional charge, provided proper documentation is submitted in advance according to federal regulations.

That said, there are some important limits to keep in mind. Each passenger is allowed to bring only one pet carrier per ticket, and each flight has a restricted number of pet spots available. Because of this limitation, pet space can fill up quickly — especially during busy travel seasons, holidays, and summer vacations.

To avoid disappointment at the airport, it’s strongly recommended to:

• Call the airline immediately after booking your ticket
  
• Confirm pet availability for your specific flight
  
• Pay any required pet fees in advance
  

Planning ahead makes the entire process smoother and helps ensure your pet gets a confirmed spot on the aircraft. With proper preparation, traveling together can be a comfortable and stress-free experience for both you and your four-legged companion. 

Sun Country Pet Carrier Guidelines

When flying with your furry companion on Sun Country Airlines, choosing the right carrier is one of the most important parts of your travel preparation. Think of the carrier as your pet’s personal travel space — it should feel safe, secure, and comfortable for the entire journey.

Your pet must remain inside an airline-approved carrier for the full duration of the flight, including boarding and landing. Even if your pet is calm or well-trained, they cannot come out of the carrier at any time while onboard. This rule is in place to protect your pet, other passengers, and the crew.

Maximum Carrier Size

To fit properly under the seat in front of you, the carrier must not exceed:

• 17 inches (Length)
  
• 12.5 inches (Width)
  
• 8.5 inches (Height)
  

Before traveling, it’s a smart idea to measure both your pet and the carrier to avoid last-minute stress at the airport.

Carrier Requirements

Sun Country recommends soft-sided carriers because they are flexible and easier to fit under seats. However, the carrier must meet the following standards:

• Soft-sided design preferred
  
• Ventilation on at least two sides for proper airflow
  
• Leak-proof or waterproof bottom lining
  
• Secure zipper or fastening system
  
• Strong enough structure to prevent collapsing
  
• Large enough for your pet to stand up, turn around, and lie down comfortably
  

Your pet should not feel cramped. If your animal looks squeezed or unable to move slightly inside the carrier, it may not be approved for travel.

Proper Identification on the Carrier

For safety reasons, passengers must clearly label the carrier with:

• Full Name
  
• Residential Address
  
• Contact Phone Number
  

This identification helps airline staff quickly contact you in case of unexpected situations, delays, or emergencies.

Comfort & Safety Tips for Your Pet

To make the experience less stressful:

• Place a small familiar blanket or toy inside
  
• Avoid overfeeding 4–6 hours before departure
  
• Take your pet for a short walk before arriving at the airport
  
• Let your pet get used to the carrier days before travel
  

A well-prepared carrier doesn’t just meet airline rules — it gives your pet a secure and calm environment during the flight.

By carefully following these carrier guidelines, you can ensure a smoother check-in process and a more comfortable journey for both you and your furry travel companion. 

Sun Country Airlines Pet Fee

Traveling with your pet is exciting, but it’s important to understand the costs involved before you head to the airport. Sun Country Airlines charges pet fees based on how your pet travels and when you add them to your reservation. Planning ahead can help you avoid higher last-minute charges and reduce stress on travel day.

Pet fees generally depend on:

• Whether your pet travels in the cabin or as cargo
  
• Whether you book the pet space in advance or on the same day
  
• Route availability and seasonal demand
  

Below is an estimated breakdown for 2026:

Type of Pet Travel	Estimated Fee (Each Way)
In-Cabin Pet	$125
Cargo / Checked Pet	$199
Advance Booking Pet Addition	Around $75
Same-Day / Airport Pet Addition	Around $100

In-Cabin Pet Fee – $125 (Each Way)

If your small dog or cat travels under the seat in front of you, the standard in-cabin pet fee is approximately $125 each way. This fee allows your pet to remain close to you throughout the journey, which many pet parents find comforting.

Cargo / Checked Pet Fee – $199 (Each Way)

For larger pets that cannot fit inside a cabin carrier, cargo travel may cost around $199 each way. Cargo services require additional handling, documentation checks, and safety monitoring, which is why the fee is higher.

Keep in mind that cargo availability depends on weather conditions and specific routes.

Advance vs Same-Day Booking Fees

Booking your pet early can sometimes reduce extra service charges.

• Adding your pet in advance may involve a lower processing cost (around $75).
  
• Waiting until the day of travel may increase the service fee (around $100), and space might not be available.
  

Because each flight allows only a limited number of pets, booking early not only saves money but also guarantees your pet’s spot.

Flying with Pets in Cabin

For many pet parents, cabin travel is the most comforting and convenient option. Having your furry companion right under the seat in front of you provides peace of mind throughout the journey. Sun Country Airlines allows small dogs and cats to travel in the cabin on eligible domestic flights, as long as all requirements are carefully followed.

Cabin travel is especially popular because it reduces separation anxiety for pets and eliminates concerns that can sometimes come with cargo transportation. However, there are clear rules designed to keep everyone onboard safe and comfortable.

Cabin Travel Rules

To ensure a smooth flight experience, the following guidelines must be followed:

• Your pet must remain inside the carrier at all times, including during boarding, taxiing, takeoff, landing, and the entire flight.
  
• The carrier must fit completely under the seat in front of you.
  
• Only one pet carrier per passenger is allowed.
  
• Passengers traveling with pets cannot sit in exit rows or bulkhead seats.
  
• The combined weight of the pet and carrier must meet airline cabin limits.
  

Even if your pet is calm and well-trained, they are not allowed to sit on your lap or move freely inside the cabin. These rules are in place to prevent disruptions and ensure safety for all passengers.

Behavior & Health Considerations

Airline staff carefully observe pets during check-in and boarding. If a pet:

• Appears sick or injured
  
• Shows signs of extreme distress
  
• Behaves aggressively
  
• Creates safety concerns
  

The airline may deny boarding for the safety of your pet and others onboard.

This is why it’s important to:

✔ Ensure your pet is healthy before travel
✔ Visit a vet if needed
✔ Allow your pet to get comfortable with the carrier in advance
✔ Avoid feeding heavy meals right before the flight

Making Cabin Travel Comfortable

To make the experience smoother:

• Place a familiar blanket or soft padding inside the carrier
  
• Take your pet for a short walk before arriving at the airport
  
• Speak calmly to help reduce anxiety
  
• Arrive early to avoid rushing
  

Cabin travel can be a stress-free and enjoyable experience when you prepare properly. With careful planning and attention to the rules, you and your pet can enjoy a safe and comfortable journey together.

Sun Country Pet Cargo Services

When your pet is too large to comfortably travel in the cabin, cargo transportation can be an alternative option. Sun Country Airlines offers pet cargo services on select routes, allowing medium and larger dogs and cats to travel safely when cabin space is not suitable.

While some pet parents may feel nervous about cargo travel, airlines follow structured safety procedures to protect animals during transit. From proper crate standards to temperature monitoring, every step is designed with your pet’s well-being in mind.

However, cargo availability depends on route, aircraft type, and weather conditions, so it’s always important to confirm details before booking.

Cargo Travel Requirements

To ensure safe and approved travel, the following conditions must be met:

• Only dogs and cats are permitted in cargo.
  
• A health certificate issued by a licensed veterinarian within 10 days of travel is required.
  
• An IATA-approved hard-sided crate must be used.
  
• Passengers must complete check-in at least 2 hours before departure.
  
• Temperature restrictions apply to protect pets from extreme heat or cold.
  

Crate Guidelines for Cargo Travel

Your pet’s crate is extremely important for cargo transport. It must:

• Be strong and escape-proof
  
• Have proper ventilation on all sides
  
• Be large enough for your pet to stand, sit, and turn comfortably
  
• Include food and water dishes attached inside
  
• Have absorbent bedding material
  

Airlines also recommend labeling the crate clearly with your name, contact details, and your pet’s name.

Weather & Seasonal Restrictions

For safety reasons, Sun Country may suspend cargo pet travel during:

• Extreme summer heat
  
• Severe winter cold
  
• Weather-related operational disruptions
  

These temporary restrictions are implemented to prevent health risks such as overheating or breathing difficulties. If weather conditions are unsafe, the airline may advise rescheduling your pet’s travel date.

Preparing Your Pet for Cargo Travel

To help your pet feel more comfortable:

✔ Allow them to get used to the crate weeks before travel
✔ Avoid heavy meals right before departure
✔ Ensure they are healthy and fit to fly
✔ Arrive early to complete documentation smoothly

Cargo travel may not be as personal as cabin travel, but with proper preparation and compliance with airline guidelines, it can be a safe and reliable option for larger pets.

Always confirm the latest cargo availability and requirements directly with the airline before finalizing your plans.

Service Animals & Emotional Support Animals

Travel rules for assistance animals have changed in recent years, and it’s important to understand the difference before flying with Sun Country Airlines. Following updates from the U.S. Department of Transportation (DOT), airlines now apply stricter definitions and documentation requirements.

These updates were introduced to improve safety, reduce misuse of ESA claims, and ensure legitimate service animal users receive proper accommodation.

Trained Service Animals

Under current federal rules:

• Only trained service dogs qualify for free travel.
  
• The dog must be individually trained to perform specific tasks for a person with a disability.
  
• Emotional comfort alone does not qualify the animal as a service animal.
  

Passengers traveling with a service dog must:

• Submit required documentation at least 48 hours before departure
  
• Complete the official DOT Service Animal Air Transportation Form
  
• Confirm the dog’s health, behavior, and training status
  

The airline may deny boarding if documentation is incomplete or if the animal shows aggressive or disruptive behavior.

Service dogs must remain under the passenger’s control at all times and should fit within the passenger’s foot space without blocking aisles.

Emotional Support Animals (ESAs)

Emotional Support Animals are no longer recognized as service animals under federal airline rules.

This means:

• ESAs are treated as regular pets
  
• Standard pet carrier rules apply
  
• ESA owners must pay normal in-cabin or cargo pet fees
  
• Space availability limitations apply
  

Even if you have a doctor’s letter for emotional support, the animal will not qualify for free travel unless it meets the DOT definition of a trained service dog.

Sun Country Pet Policy Restrictions

While Sun Country Airlines welcomes certain pets on domestic flights, not all animals are eligible for travel. These restrictions are in place to protect animal welfare, ensure passenger safety, and comply with federal aviation and health regulations.

Before planning your trip, it’s important to understand which animals the airline does not permit.

Animals That Are Not Allowed

The following types of pets are not accepted for cabin or cargo travel:

• Birds
  
• Reptiles (such as snakes, turtles, or lizards)
  
• Rodents (including hamsters, guinea pigs, or mice)
  
• Farm animals
  
• Exotic or unusual animals
  

In addition, the airline will not transport:

• Sick or injured animals
  
• Pregnant pets
  
• Pets showing signs of distress or aggressive behavior
  
• Animals without proper health documentation (when required)
  

Airlines designed these rules to reduce health risks, prevent in-flight disruptions, and ensure humane treatment of animals during air travel.

What Is Allowed?

Only domestic cats and dogs are permitted under the current pet policy. The airline must approve them after they meet all carrier, size, health, and documentation requirements for travel.

If your pet does not fall under the approved category, you may need to explore alternative travel options such as ground pet transport services.

Why These Restrictions Matter

Air travel can be stressful for animals, especially those sensitive to noise, altitude changes, or temperature shifts. By limiting travel to cats and dogs that meet safety standards, the airline aims to:

✔ Protect animal health
✔ Ensure passenger comfort
✔ Maintain cabin safety
✔ Follow federal transport guidelines

Before booking, it’s always wise to confirm eligibility and review documentation requirements. Proper preparation prevents last-minute surprises and helps ensure a smooth travel experience for both you and your pet. 

How to Book Pet Travel on Sun Country Airlines

Planning ahead is the key to a smooth journey when flying with your furry companion. One important thing to remember is that you cannot reserve pet space directly through the standard online booking system. Because pet spots are limited on each flight, you’ll need to take an extra step to secure your pet’s place.

Since airlines restrict availability, it’s always better to arrange pet travel as soon as you book your ticket.

Booking Methods

Here are the official ways to add your pet to your reservation:

Call Customer Support

This is the most reliable method. After purchasing your ticket, contact the airline’s customer service team and inform them that you will be traveling with a pet. They will:

• Check pet availability on your specific flight
  
• Confirm carrier and size requirements
  
• Add the pet to your reservation
  
• Collect the applicable pet fee
  

Booking over the phone helps avoid last-minute surprises.

Add Your Pet at the Airport Counter

If you were unable to add your pet in advance, you may try to add them during check-in at the airport. However:

• Pet space may already be full
  
• Same-day service fees could be higher
  
• There is no guarantee of availability
  

This option is riskier, especially during busy travel seasons.

Use the Official Contact Form

Some travelers prefer submitting a request through the airline’s official website contact form. While this can work, it’s important to follow up and confirm approval before your travel date.

Why Advance Booking Matters

Each flight has a limited number of pet slots in the cabin. Even if passenger seats are available, pet capacity may be full. Waiting too long could mean:

• Your pet cannot travel on your chosen flight
  
• You may need to reschedule
  
• You may face higher same-day fees
  

Booking early provides peace of mind and ensures your pet has a confirmed spot.

Important Things to Remember

Before flying with your furry companion on Sun Country Airlines, it’s important to keep a few key rules in mind. These small details can make a big difference in ensuring a smooth airport experience and a stress-free flight for both you and your pet.

Here are the most important points every pet parent should remember:

Pets Count as One Carry-On Item

When you bring a pet in the cabin, their carrier is considered your carry-on bag. This means:

• You may need to adjust your luggage plans.
  
• If you already have a carry-on suitcase, you might need to check it instead.
  
• Personal item rules still apply (like a small purse or laptop bag).
  

Planning your packing in advance helps avoid confusion at the gate.

🇺🇸 Domestic Flights Only

Pets are allowed only on domestic U.S. routes. International pet travel is not permitted under current airline policy. If you’re traveling outside the United States, you’ll need to explore alternative arrangements.

Limited Pet Slots Per Flight

Each aircraft allows only a small number of pets in the cabin. Even if passenger seats are available, pet capacity may already be full. This is why booking early is strongly recommended.

During holidays and peak travel seasons, pet spots can fill up quickly.

No International Pet Transport

Sun Country does not currently offer pet transportation on international routes. This includes both cabin and cargo services. Always confirm route eligibility before finalizing your plans.

Cabin Pets Must Remain Under the Seat

If your pet is traveling in the cabin:

• The carrier must fit completely under the seat in front of you.
  
• Your pet must stay inside the carrier at all times.
  
• Pets cannot sit on laps or move freely inside the aircraft.
  

These rules ensure safety for your pet, other passengers, and the flight crew.

Expert Tips for Stress-Free Pet Travel

Flying with your furry companion on Sun Country Airlines can be a smooth and positive experience — if you prepare properly. Pets are sensitive to new environments, loud noises, and routine changes, so a little planning goes a long way in reducing stress for both of you.

Here are expert-backed tips to make the journey calmer, safer, and more comfortable:

✔ Book Early

Pet spots on each flight are limited. As soon as you book your ticket, contact the airline to reserve your pet’s space. Waiting until the last minute can lead to disappointment or higher fees.

✔ Visit Your Vet Before Flying

Schedule a check-up a few days before travel to ensure your pet is healthy and fit to fly. Ask your vet about:

• Required health certificates
  
• Vaccination updates
  
• Travel-related anxiety advice
  

A healthy pet handles travel much better.

✔ Train Your Pet with the Carrier Beforehand

Don’t introduce the carrier on travel day. Let your pet:

• Spend time inside it at home
  
• Sleep in it occasionally
  
• Associate it with treats and comfort
  

Familiarity reduces panic and anxiety at the airport.

✔ Carry Vaccination & Health Records

Even if not always requested, it’s smart to keep copies of:

• Vaccination records
  
• Health certificates
  
• Identification documents
  

Having paperwork ready avoids delays and gives peace of mind.

✔ Arrive at the Airport Early

Traveling with a pet requires extra time for:

• Documentation checks
  
• Security screening
  
• Pet carrier inspection
  

Arriving early helps you stay calm — and pets pick up on your energy.

✔ Keep Emergency Contact Details Updated

Label the carrier clearly with:

• Your full name
  
• Phone number
  
• Backup emergency contact
  

In rare cases of separation or delay, updated information ensures quick communication.

Avoid Tranquilizers Unless Prescribed

Do not give sedatives unless specifically recommended by a licensed veterinarian. Sedation can affect breathing and balance at high altitudes. Most vets recommend natural calming techniques instead of medication.

Conclusion

Flying with your furry companion on Sun Country Airlines can be a safe and comfortable experience if you follow the airline’s pet travel rules. Proper preparation — from choosing the right carrier and securing your pet’s spot early to ensuring health and behavior requirements — helps prevent delays, extra charges, or denied boarding. Understanding pet fees, cabin and cargo options, and service animal regulations allows you to plan confidently.

With careful planning and attention to your pet’s comfort and safety, traveling together can be smooth and stress-free, turning your journey into an enjoyable adventure for both you and your four-legged friend.
