Starting June 3rd, Aeroflot will be increasing their 7 weekly flights to 11 weekly flights with the introduction of an earlier afternoon flight.

SU313 will operate on Tuesday, Thursday, Friday, and Saturday and will arrive at 12:20pm and depart at 2:40pm. All flights to JFK will be operated by the 767-300 this summer, although I am sure that is subject to change.
