What the aircraft actually flies over
From London the path crosses United Kingdom, then Ireland, then 3,013 km of open water, then Canada, then the United States.
The furthest the great circle gets from the equator is 56.1°N, 28% of the way along.
Flying the line that looks straight on a Mercator map — one constant compass bearing — would cover 8,131 km. That is 504 km further, about 7% more, and roughly 38m of extra flying.
Leaving London the aircraft points north-west (296°); it arrives into Dallas-Fort Worth heading south-west (222°). That is 75° of drift without a single turn — the compass moves because the path is a curve on a sphere, not because the aircraft does.
