About great circle distance
The great circle distance is the shortest path between two points over the surface of the earth, the line a long flight follows before winds and airways bend it. Airlines use it to award distance-based miles. Distances here use the haversine formula with a mean earth radius of 3,958.8 statute miles (3,440.065 nautical miles, 6,371.0088 km). Each leg is rounded to a whole number, and totals add up the rounded legs. Airports are matched by their 3-letter IATA or 4-letter ICAO code; type a city in the search box if you are not sure of one.
