Turkish Airlines has tentatively agreed to acquire another seven Airbus A330 aircraft.
It has signed a memorandum of understanding for the twin-jets, five of which will be A330-300s.
The remaining two will be the higher-weight version of the A330-200.
Turkish Airlines has not given an engine selection for the aircraft - although its seven current A330s are General Electric CF6-powered.
Airbus, which disclosed the agreement during the Paris Air Show, says the aircraft are scheduled for delivery from August next year.
Turkish Airlines chairman Candan Karlitekin says the higher-weight A330-200s will allow the carrier to expand its network on routes such as Istanbul-New York.
The A330-300s, he adds, will be deployed on high-capacity medium-haul sectors.
Turkish Airlines is preparing to confirm details of a large order expected to comprise more than 100 aircraft.
