Russian flag-carrier Aeroflot has signed a new leasing agreement with state corporation Rostekhnologii covering the acquisition of 50 Boeing 737-800s and -900ERs.
Rostekhnologii's original 50-jet deal with Boeing had featured 737-700s in the mix, but Aeroflot has only identified the larger variants as being part of the lease.
"The number of each variant will be determined closer to the time of delivery to Aeroflot," said the airline.
Delivery is set to take place between September 2013 and 2017, the carrier said, adding that the pact centred on a 144-month lease period.
It will take the jets through Rostekhnologii subsidiary Aviakapital-Servis.
Aeroflot said the lease is linked to its expansion through the acquisition of several regional carriers which were previously assets under Rostekhnologii.
