A friend is taking SU107 from LAX to SVO today, and I’m tracking it on FlightAware. Much to my surprise, the indicated flight path turns right (maybe 30 degrees?) over the North Sea, grazing Norway, Denmark, and Sweden, then over the Baltic Sea continuing over all of Poland, into Ukraine, and then a 90-degree turn left, taking it over Ukraine, Belarus, and finally Russia into Moscow.
This would seem (from eyeballing Google Earth) to add about 500 miles to the great circle route. In fact, FlightAware says that the “planned” distance is 7,185 miles, compared to “direct” of 6,070 miles.
What gives? Was there ever any public announcement?
