What the aircraft actually flies over
From Dublin the path crosses Ireland, then 3,122 km of open water, then Canada, then 528 km of open water.
The furthest the great circle gets from the equator is 54.4°N, 21% of the way along.
Flying the line that looks straight on a Mercator map — one constant compass bearing — would cover 4,956 km. That is 153 km further, about 3% more, and roughly 11m of extra flying.
Leaving Dublin the aircraft points west (283°); it arrives into Boston heading south-west (232°). That is 51° of drift without a single turn — the compass moves because the path is a curve on a sphere, not because the aircraft does.
