Turkish Airlines (TK, Istanbul Atatürk) is considering placing an order with Boeing (BOE, Chicago O'Hare) for the B777X Family of aircraft, airline chairman Ilker Ayci has revealed.

"We’re still making our calculations and working very closely with the OEMs on the feasibility of the new generation aircraft for the ultra-overseas," he told The National newspaper in Sydney last week. "After we’ve seen the clear feasibility of that aircraft’s performance, we’ll make our decision."

As with the rest of Turkish's orders, it is presumed Airbus's A350 Family of jets - the -900 (ULR) and -1000 - is also being looked at.

Once the feasibility study has been completed, Ayci said Turkish Airlines may then consider placing a "trial" order to determine the type's compatibility with the carrier's operations. Should it prove viable, a "main" order would then be placed.

Turkish Airlines currently has twenty-five firm and five options each with Airbus and Boeing for their A350-900 and B787-9 products respectively.

Barring any unforeseen incidents, the first B777-9 is due to deliver to launch operator Emirates (EK, Dubai Int'l) in 2020.
