Given that pets are an essential part of the family, Sun Country Airlines Pet Policy aims to accommodate travelers who wish to bring their small animals on board. The airline allows domesticated cats and dogs to travel in the main cabin, provided they meet certain size and behavior requirements. Pets must be transported in soft-sided containers that fit snugly under the front passenger seat in order to guarantee everyone's safety and comfort. Reservations must be made long in advance to guarantee a spot because the airline only permits a specific number of pets per flight. 

Each person is only allowed one pet per carrier, and the carrier must remain closed the entire time. This ensures the pet's safety and lessens disturbances to other travelers. Unlike a number of other carriers, Sun Country does not transport animals in the cargo area. Since all pets must ride in the cabin, only small pets are permitted. Passengers should ensure that their pet is calm, well-behaved, and used to confined spaces because the pet must remain inside the carrier from the time of boarding until the pet arrives.

Even if Sun Country does not require a health certificate for travel within the United States, it is the passenger's responsibility to confirm any health or admission requirements at their destination. The airline also forbids a number of creatures, such as birds, rodents, and reptiles. Due to Sun Country Airlines' clear standards and emphasis on in-cabin safety, pet owners can travel with greater peace of mind if their animal meets the airline's requirements.
