About Turkish Airlines
Turkish Airlines is the national carrier of Turkey and a member of Star Alliance. Its network is built around Istanbul Airport, which sits between Europe, Asia and Africa, so a large share of its passengers change planes there on the way to somewhere else. The airline flies across Turkey and to cities in Europe, the Middle East, Central Asia, Africa, the Far East and the Americas. It sells Business and Economy cabins, and its low-cost brand AJet covers many domestic and short leisure routes.
On IATA.co you can search live Turkish Airlines fares in the booking portal or request them through the flights API, then pay from your prepaid balance. Turkish Airlines fares appear in your search results whenever our flight suppliers offer them for your route and dates. Fare rules, including baggage and change conditions, are shown before you confirm, which is useful when you are quoting a connecting itinerary through Istanbul for a client.

Booking Turkish Airlines fares as a travel agent
Travel agents book Turkish Airlines fares on IATA.co without their own IATA accreditation. Activate an agency account, top up a prepaid balance, then search live TK fares in the booking portal: the price, baggage and fare rules are shown with each offer before you confirm, and the amount is deducted from your balance. Turkish Airlines results appear whenever our flight suppliers return them for your route and dates, so what you can book follows live supplier content rather than a direct airline deal.
Search Turkish Airlines (TK) through the flights API
Developers and agencies can run the same Turkish Airlines search from their own site, app or back office through the IATA.co flights API. Filter a search by the carrier code TK and read the fares back as JSON, then book from the same prepaid balance. See the flights API and the API docs for the full reference.
