I meant to say "Unusual to me, because I have not observed this particular flight path after more than a dozen or so IAD-NRT-IAD flights.

The plane took off from NRT and followed pretty much the same flight path as NRT-SFO, and then somewhere north of SFO (within CA airspace) it turn into a typical SFO-IAD transcon path.



Most of the NRT-IAD path I have observed are:

Plane goes north towards the polar area then come down through Canada, and then enters the US space somewhere north of the Midwest region.

Has anyone experience the same flight path I have experienced yesterday?
