I enjoyed a hassle-free flying experience with Sun Country JFK Terminal. Check-in was simple, and the attendants were courteous and cooperative. Security queues were not crowded, and moving around to the gate was stress-free. Sun Country has a neat and tidy facility with adequate seating and dining facilities. Although not the fanciest of terminals, it is functional and stress-free. Overall, flying with Sun Country in JFK Terminal offers a smooth and comfortable experience.
