Traveling with a pet can feel overwhelming, especially when airline rules are unclear or constantly changing. The Sun Country Airlines Pet Policy aims to keep things simple, affordable, and manageable for travelers flying with small pets. Still, knowing the fine print before booking can make the difference between a smooth journey and an airport surprise.

This guide breaks down everything that matters—from eligible pets and carrier rules to fees, restrictions, and helpful travel tips—so pet owners can plan with confidence.

Overview of Sun Country Airlines Pet Policy

Sun Country Airlines allows pets to travel in the aircraft cabin on select domestic flights. The policy is designed for small cats and dogs that can comfortably fit in an approved carrier under the seat.

Unlike some airlines, Sun Country does not transport pets in the cargo hold. This keeps pets closer to their owners but also limits options for larger animals. Availability is limited per flight, making early planning essential.

Understanding the Sun Country Airlines Pet Policy before booking helps avoid last-minute issues and unexpected costs.

What Types of Pets Are Allowed?

Sun Country Airlines keeps its pet policy very specific.

Allowed Pets

• Small cats

• Small dogs

Only domesticated cats and dogs are accepted as pets. Other animals, including birds, reptiles, rodents, or exotic pets, are not permitted on board.

Pets must be clean, odor-free, and healthy enough to travel. Aggressive behavior or excessive noise may result in denied boarding.

In-Cabin Pet Travel Rules

All pets traveling with Sun Country Airlines must fly in the cabin. Cargo transport is not offered under any circumstances.

Key In-Cabin Rules

• Pets must remain inside the carrier at all times

• The carrier must fit completely under the seat

• One pet is allowed per ticketed passenger

• Only one pet per carrier is permitted

• Limited pet spots are available on each flight

Because space is limited, pet reservations should be made as early as possible. Waiting until the airport often leads to disappointment.

Routes Where Pets Are Allowed

Sun Country Airlines accepts pets only on certain routes.

Pet-Friendly Routes

• Domestic flights within the 48 contiguous United States

Routes Where Pets Are Not Allowed

• International flights

• Flights to or from Alaska

• Flights to or from Hawaii

• Flights to Puerto Rico

• Flights to the U.S. Virgin Islands

• Connecting or multi-city itineraries

Pets are allowed only on nonstop domestic routes. Travelers with layovers or international plans must explore alternative arrangements.

Pet Carrier Requirements

Carrier compliance is one of the most important parts of the Sun Country Airlines Pet Policy. If the carrier does not meet requirements, boarding may be denied.

Approved Carrier Type

• Soft-sided carriers only

• Leak-proof bottom

• Adequate ventilation on multiple sides

Size Guidelines

The carrier must fit completely under the seat in front of the passenger. While seat dimensions vary by aircraft, carriers should generally measure around:

• 16 inches long

• 10 inches wide

• 8 inches high

Hard-sided carriers are not accepted.

Pet Comfort Rules Inside the Carrier

Sun Country Airlines requires pets to be comfortable inside the carrier.

The pet must be able to:

• Stand up

• Turn around

• Lie down naturally

Overcrowded carriers or visibly distressed pets may be denied travel. A well-ventilated, padded carrier makes a noticeable difference during the flight.

Pet Fees and Charges

Flying with a pet on Sun Country Airlines comes with a non-refundable fee.

Pet Fee Structure

• Fee is charged per pet, per one-way flight

• Fees are non-refundable, even if travel plans change

Fees may vary depending on whether the pet is added during booking or at the airport. Adding a pet in advance is strongly recommended, both for availability and cost control.

Always confirm the latest fees before travel, as pricing may change.

How to Add a Pet to a Booking

Adding a pet to a Sun Country Airlines reservation is simple but time-sensitive.

Steps to Add a Pet

1. Book the flight first

2. Add the pet during the booking process or through customer support

3. Pay the pet fee

4. Confirm carrier compliance before travel day

Pet reservations cannot be guaranteed at the airport if cabin capacity has already been reached.

Check-In and Airport Procedures

Arriving prepared makes the airport experience much easier when traveling with a pet.

Airport Check-In Tips

• Arrive early to allow time for verification

• Keep the pet inside the carrier at all times

• Expect carrier inspection at security

• Remove the pet during TSA screening while the carrier goes through X-ray

Leash control during security screening is essential. Calm handling helps reduce stress for both pets and owners.

Onboard Pet Travel Guidelines

Once on board, pets must remain secured under the seat for the entire flight.

Onboard Rules

• No opening the carrier mid-flight

• No placing the carrier on the lap or seat

• No feeding pets during the flight

• Noise or disruptive behavior may require intervention

Choosing a window seat often reduces foot traffic and helps pets feel more secure.

Service Animals vs. Pets

The Sun Country Airlines Pet Policy distinguishes clearly between pets and trained service animals.

Service Animals

• Fly free of charge

• Must be trained to perform specific tasks

• Required documentation may apply

• May travel on routes where pets are restricted

Emotional Support Animals

• Treated as pets

• Subject to pet fees

• Must meet carrier and route restrictions

Understanding this difference prevents confusion during booking and boarding.

Health and Documentation Requirements

Sun Country Airlines does not require health certificates for most domestic pet travel. However, some states or destinations may have specific regulations.

Recommended Preparation

• Updated vaccinations

• Recent wellness check

• Pet ID tags

• Absorbent padding inside the carrier

While documentation may not be required by the airline, having records available adds peace of mind.

Breed and Size Considerations

There are no published breed restrictions under the Sun Country Airlines Pet Policy, but size limitations effectively restrict travel for larger breeds.

Pets must fit comfortably in a carrier under the seat. Brachycephalic (short-nosed) breeds should be evaluated carefully due to potential breathing issues during flight.

Seasonal and Weather Considerations

Extreme temperatures can impact pet travel comfort.

Helpful Seasonal Tips

• Avoid midday flights in hot weather

• Choose climate-controlled aircraft

• Hydrate pets before travel

• Use cooling mats or breathable carriers when appropriate

While pets stay in the cabin, comfort remains a priority year-round.

Common Reasons Pets Are Denied Boarding

Understanding common mistakes helps avoid travel disruptions.

Frequent Issues

• Oversized carriers

• Late pet reservations

• Aggressive or anxious behavior

• Pets unable to stand or turn inside the carrier

• Restricted routes or connecting flights

Double-checking requirements before departure reduces the risk of denied boarding.

Tips for Stress-Free Pet Travel

A little preparation goes a long way.

Practical Tips

• Introduce the pet to the carrier weeks before travel

• Avoid feeding pets right before departure

• Bring familiar blankets or toys

• Exercise pets before heading to the airport

• Keep calm—pets sense stress

Comfortable pets make for smoother flights.
