Took IAD-PEK this past Saturday (Jan 3rd).
Flight took a eastbound path versus the usual westbound path over canada/eastern Siberia.
Flight Path Map showed progress for about 11+ plus hours, then my TV monitor changed and all the sudden my seatmate's stayed the same.
See photos below.
About an hour before the the screen changed, I looked out the window and could see Lake Baykal below the plane. Both on the physical identification of the lake, the flight path map shown on my monitor appeared to be incorrect.
What was going on? Anyone experienced this before?
