Russian carrier Transaero is planning to break from its traditional preference for Boeing aircraft with an order for Airbus A320neos.
The Moscow-based airline disclosed a memorandum of understanding for eight of the type at the MAKS Moscow air show.
Transaero has an all-Boeing fleet apart from a couple of Tupolev Tu-214s.
The tentative order, if firmed, would make Transaero the launch customer for the A320neo in Russia.
It has not made an engine selection between the CFM International Leap and the Pratt & Whitney PW1100G.
"Operation of these new, very efficient aircraft will allow us to create optimal conditions for passengers on the expanding network of domestic and international destinations," said Transaero chief Olga Pleshakova.
