There are three international airports in Jamaica with modern terminals, long runways, and the navigational equipment required to accommodate the large jet aircraft used in modern and air travel: Norman Manley International Airport in Kingston; Ian Fleming International Airport in Boscobel, Saint Mary Parish; and the island's largest and busiest airport, Sir Donald Sangster International Airport in the resort city of Montego Bay. Manley and Sangster International airports are home to the country's national airline, Air Jamaica. In addition there are local commuter airports at Tinson Pen (Kingston), Port Antonio, and Negril, which cater to internal flights only. Many other small, rural centres are served by private airstrips on sugar estates or bauxite mines.
