What the aircraft actually flies over
From Reykjavík the path crosses 2,218 km of open water, then Canada, then the United States.
The furthest the great circle gets from the equator is 64.0°N, 0% of the way along.
Flying the line that looks straight on a Mercator map — one constant compass bearing — would cover 3,952 km. That is 77 km further, about 2% more, and roughly 6m of extra flying.
Leaving Reykjavík the aircraft points west (255°); it arrives into Boston heading south-west (215°). That is 40° of drift without a single turn — the compass moves because the path is a curve on a sphere, not because the aircraft does.
