About these distances

Distances are computed as great-circle (orthodromic) distances from the coordinates in the public-domain NGA World Port Index and OurAirports datasets. They represent the shortest path over the Earth’s surface, not the operational sea or air route, which is longer. Transit estimates are honest approximations for planning, not schedules.
