Have a question about two specific air routings over the ocean from Europe to the USA and back..
In particular, the routing from ARN-EWR on SAS....I'm curious as to whether this flight takes a direct..."great circle" routing which takes it over the north atlantic, passing just south of Greenland, over eastern Canada, before finally dropping down into Newark....or if it takes a polar route...flying over the north pole and then south over Canada to Newark?
Second routing, LAX-FRAnkfurt on LH. Does this route fly eastbound over the USA, before crossing the Atlantic...and does this also fly to the south of Greenland? OR, does it fly north, over the pole, and then down into Germany....OR...does this flight actually go transpacific?
Do airlines prefer polar flights or great circle routes?

The North Atlantic Tracks change on a daily basis, so as to take advantage of winds aloft.
Therefore, these flights would have a slightly different routing each day, however it generally would be in the same area...:ie: no massive route changes.
Aircraft can also file 'random routes'. These are sometimes very close to great circle routings however, care must be exercised so as not to select a routing that crosses too many (daily) fixed tracks, as optimum altitudes may not be available due to crossing traffic, at certain times of the day.
Polar routing for the flights mentioned would not be advantageous, due to the distance involved.

LH flightplan is LAX to the Thermal 031 radial 14 nm, then direct to Sioux Narrows? Boy... I knew once airborne they could hope for direct routings like that, but I didn't think flight plans had 1000+ miles of direct.

I flew ORD-ARN on SK last year and we passed (if I remember it correctly) a little north of New Foundland and over Greenland and since Chicago is further away from Stockholm than New York is, there's no crossing of the pole on the EWR-ARN route.
