Turkish Airlines won't announce a plane order at this week's Farnborough Airshow, with a deal for narrowbody jets still held up by negotiations over engines, Chairman Ahmet Bolat told reporters at the show on Monday.

The airline had said last month it was advancing talks with Boeing for 150 737 MAX narrowbody jets and 75 widebody 787 planes, but a final decision hinged on engine price negotiations.

"We are not going to announce anything in Farnborough," Bolat said, adding he had discussions on Monday morning with engine supplier GE.
