Russian airlines carried 5.96 million passengers in January-April 2016, down 6.4% year-over-year (YOY). International traffic is down 24.2% to 2.06 million, while domestic traffic is up 6.8% to 3.9 million. The results could be explained with economic turbulence, as well as flights to Egypt suspended and a charters ban to Turkey implemented, ATWonline reported.
