Turkish Airlines HEL Terminal +1-888-839-0502 Hello! We recently passed through Turkish Airlines HEL Terminal and it was great! Helsinki Airport is the cleanest and most tidy airport we have ever been to. The check-in crew was friendly and friendly, and it was easy. Security was quick, and we had time to have a nice meal before taking off. visit us https://www.flytermial.com/turkish-airlines/turkish-airlines-hel-terminal-helsinki-airport/
