St. John's International Airport is located 3 nautical miles northwest of St. John's, Newfoundland and Labrador that serves the St. John's Metro Area and the Avalon Peninsula. With a few exceptions, airport codes starting with ‘Y’ designate Canadian airports. The second ‘Y’ is a filler letter and the ‘T’ comes from its former name, Torbay Airport. This helps differentiate it from the other Saint John Airport (YSJ).
