Russian carrier UTair has taken over Siberian charter operator Katekavia as part of ongoing efforts to broaden its regional reach.
Katekavia general manager Alexander Zosimov says the deal for an undisclosed sum is "based on mutual interests and will be of benefit to both sides".
UTair chief executive Andrei Martirosov adds that the acquisition is in line with his carrier's strategy of expanding Siberian operations.
UTair last year also took control of Khabarovsk-based charter and aerial services specialist Vostok Airlines.
Katekavia provides charter flights from Krasnoyarsk and Ufa. Its major customers include oil and gas producers as well as logistics, construction and coal mining companies.
Katekavia also operates socially-important services to three destinations within the Krasnoyarsk region. In 2011, it transported 115,000 passengers with nine Antonov An-24RV turboprops and two Tupolev Tu-134A jets.
Zosimov says all the aircraft have been fitted with TCAS/GPWS safety equipment, as requested by regulators, adding: "The decision for our fleet renewal will now be up to UTair."
