The new SVO1 opened on March, 12. It's now called Terminal C (SVO3 will be Terminal A and the new SVO2 Terminal B). Airlines using it so far are Aeroflot (their CIS flights that used to operate from SVO1, I presume), Aeroflot-Don, Aeroflot-Nord, Air Algérie, flyLAL, Air Astana and Aerosvit. More carriers are expected to relocate after March, 25
