Aeroflot will transfer some flights from Moscow Sheremetyevo to Vnukovo airport in the winter schedule 2013-14 due to infrastructure limitations at Sheremetyevo Airport.

Details of the transfer were not immediately disclosed, but an Aeroflot spokesperson said they will be announced after May 15. The airline is expected to mainly move its leisure destinations routes that are not connected with other flights.

Sheremetyevo Terminal D, constructed by Aeroflot, can handle up to 12 million passengers per year, which falls short of Aeroflot’s 17.7 million passengers carried in 2012.

Last year, Aeroflot signed an agreement with Sheremetyevo to release airport terminals D, E and F for the carrier, its sister companies and SkyTeam partners. The three terminals have a total capacity of around 30 million passengers per year. Aeroflot had planned to occupy the terminals in 2014, but Russia’s Federal Antimonopoly Service (FAS) blocked the initiative. Aeroflot and authorities have not yet reached a final agreement on Sheremetyevo.

Last year, Transaero transferred some of its flights from Domodedovo to Vnukovo due to capacity issues.
