Also in areas like Alaska we have volcanic activity which causes frequent changes to flight plans. I would most likely assume though it was due to different wind speed / directions for the flight above.

Just for the sake of further discussion, and not to discount the rationale of the previous responders, is it possible that the flight track shown by Flightaware for EK211 on 8Jan is not precisely the route flown on that particular date? From one date to the next, the variation in the plotted tracks is not just huge, but (virtually) off the chart!
I actually flew on EK 211 on Jan 8 and we flew right over the North Pole. The Flightaware track flattens out at the top, but in reality we went polar that day. I was expecting a day flight, but as we headed towards the North Pole it got darker, and eventually it was night only for a few hours. I took pics of the flight map and will post it on a trip report when I get to it- hopefully soon.
One clarification, the second track link is from Jan 12.

World Air Routes is a company based in Boston that produces a lot of high quality flight deck videos. They have one with Air Canada where they actually take you on a Polar Route from YYZ to HKG, and explain a lot of the things that go into planning such a route, including a lengthy presentation by the dispatcher. I think the video will help answer a lot of questions, and it is $30 US, a very good deal IMO.
