Sun Country JFK Terminal +1-888-839-0502 I found my Sun Country JFK Terminal experience to be satisfactory. The check-in process was speedy, and the people were courteous, so the experience was seamless. Security was not too lengthy, and the terminal itself was clean and accessible. There were a few good places to eat, and there was seating available, though it could get crowded every now and then. Although it is not the newest terminal, it is an easy experience for passengers. Sun Country is generally a hassle-free and smooth location to begin your trip. visit us : https://www.terminalsme.com/sun-country-airlines/sun-country-jfk-terminal-john-f-kennedy-international-airport/
