What the aircraft actually flies over
From Dallas-Fort Worth the path crosses the United States, then Mexico, then 12,117 km of open water.
The furthest the great circle gets from the equator is 33.9°S, 100% of the way along.
Flying the line that looks straight on a Mercator map — one constant compass bearing — would cover 13,864 km. That is 55 km further, about 0% more, and roughly 4m of extra flying.
It arrives on almost the heading it left on — west at both ends. The two airports sit at nearly mirrored latitudes, so the arc climbs away from the equator and falls back to it by the same amount, and the compass ends up where it started.
