Turkish Airlines will request US Export-Import Bank support for its upcoming Boeing 737 deliveries, according to the export credit agency.
No further details were provided about the carrier's financial request.
In November 2012, Turkish finalised an order for 15 Boeing 777-300ER aircraft worth $4.7 billion at list price.
The agreement, first announced as a commitment in October, also includes options for an additional five aircraft of the same type.
This order will add to Turkish's existing fleet of 12 777-300ERs and be used on its long-haul operations.
In early October, the carrier also signed an agreement with Airbus for 15 A330-300s and would have 27 of the type when the deliveries are completed in 2016.
Flightglobal's Ascend Online database shows that Turkish Airlines operates a fleet of 174 aircraft, comprising 12 777s, 21 A330s, seven A340s, 75 A320-family jets and 59 737s.
