VIM-Avia has signed an agreement to acquire two Airbus A319s.
The Russian carrier is looking to take delivery of both aircraft in the first quarter of 2014.
The narrowbodies will be deployed on existing routes and new ones to be launched under VIM-Avia's network expansion plans.
Moscow-based VIM-Avia says it will continue diversifying its fleet, which currently consists of Boeing 757-200s.
Flightglobal's Ascend Online database lists seven 757-200s in the airline's active fleet.
In August, VIM-Avia placed orders for five Tupolev Tu-204s and five Bombardier CS300s.
