Domodedovo is going down. I used it twice last week and was unpleasantly surprised on both arrival and departure. On arrival the immigration was a mess. Huge crowds of people arriving from international flights and only one third of booths manned. No line management at all. People jumping a queue unhelpful and arrogant staff. On departure I've noticed a very certain lack of fresh air in the newly opened part of the departures hall. Once at an earlier built area an air becomes normal. Dirty toilets inefficient security.
