Airlineroute.net reports that Turkish Airlines started selling reservations to Buenos Aires - Ezeiza in GDS (Global Distribution Systems) on Saturday, 17Nov12.
The service will be an extension of the carrier's four-times weekly Istanbul (IST) to Sao Paulo (GRU) flights operated by 777-300ER's. The move is part of the airline's aggressive expansion to be a viable alternative to Emirates, Etihad, and Qatar Airways connecting East and West through the Middle East (or close to it). The airline recently also announced new service to Boston (BOS) and claims in its advertising that it flies to more countries than any other airline in the world.
The flights will operate as follows:
Flight Leg 1 Leg 2 Equipment Frequency
TK015 IST 0920 - GRU 1900 GRU 2015 - EZE 2155 777-300ER 2,3,5,7
