Eighteen Russian operators have been approved to receive subsidies under a Rb23.4 billion ($339 million) government programme to ease financial pressures during the coronavirus crisis.
Another 13 have applied, says federal air transport regulator Rosaviatsia, but the documentation for these applications is still undergoing review.
The government set out the conditions for the subsidies in a 13 May decree, which details a formula to calculate the size of the support.
At least 60% of the funding should be put towards compensating labour costs, up to 30% to cover leasing payments and no more than 10% for airport expenses relating to aircraft parking.
The 18 approved operators will collectively receive Rb9.45 billion to cover expenditures to April 2020.
These carriers include Aeroflot, Rossiya, Azimuth, Red Wings, Ural Airlines, S7 Airlines, Utair, Nordwind, and Smartavia, among others. The other 13 applicants are seeking subsidies totaling Rb238 million.
