Thanks for your answer. I certainly remember KE002, the flight where anti-communist congressman Larry McDonald and hundreds of others perished when the flight "strayed" over Soviet airspace (if you believe the Russians). I wasn't sure what the status of Russian airspace is today, since theoretically at least the cold war ended with the collapse of the USSR, and Aeroflot is a SkyTeam partner of Delta's.
