Turkish Airlines began in May 1933 as the State Airlines Administration. It was a five-aircraft branch of Turkey's Ministry of National Defense, flying short domestic trips from Ankara. The airline was reorganized as Turk Hava Yollari in 1956 and joined IATA, the global airline trade body. It grew slowly as a state carrier, took up jets, then added intercontinental routes in the 1980s.
Partial privatization started in the 1990s, meaning private investors bought part of the company. The real change came after it joined Star Alliance in 2008, a group whose members feed passengers onto each other's flights. Turkish built its plan around Istanbul's position, within single-aisle range of most of Europe, Africa, the Middle East, and Central Asia. Single-aisle jets are the smaller, cheaper planes that airlines use most.
Today it serves more countries than any airline in the world, over 120, and reaches some 340 destinations. In April 2019 it pulled off a rare feat. It moved its whole hub from Ataturk Airport to the vast new Istanbul Airport in about 45 hours. A hub is an airport where an airline gathers flights so travelers can change planes. Turkish stays profitable at a scale few flag carriers match.
