Siberian carrier Yamal has defined the timeframe for receiving additional Western-built aircraft this year.
The airline's chief Vasily Kryuk says it is preparing to take delivery of seven Bombardier CRJ200 jets.
It also wants to introduce three Airbus A320 aircraft at the end of March and a further three in June. The airline currently has only one of the type.
It is not yet clear whether Yamal plans to retain its two leased Boeing 737-500s and two 737-400s or start phasing them out after the high season.
