## What the aircraft actually flies over

From Dublin the path crosses Ireland, then 3,126 km of open water, then Canada, then 536 km of open water, then the United States.

The furthest the great circle gets from the equator is 54.4°N, 20% of the way along.

Flying the line that looks straight on a Mercator map — one constant compass bearing — would cover 5,277 km. That is 173 km further, about 3% more, and roughly 13m of extra flying.

Leaving Dublin the aircraft points west (282°); it arrives into New York heading south-west (230°). That is 52° of drift without a single turn — the compass moves because the path is a curve on a sphere, not because the aircraft does.

One economy seat on it is about 723 kg of CO₂e each way, counting non-CO₂ warming.
