Great-circle distance
Distances use city latitude and longitude with the Haversine formula, which measures the shortest path over the earth's surface.

Flight time estimate
The flight estimate adds realistic block-time overhead to a typical nonstop cruise speed, so it is useful without pretending to be a live airline schedule.
