Nonstop flight route between Yankton, South Dakota, United States and San Antonio, Texas, United States:

About this route:

A direct, nonstop flight between Chan Gurney Municipal Airport (YKN), Yankton, South Dakota, United States and Lackland Air Force Base Joint Base San Antonio (SKF), San Antonio, Texas, United States would travel a Great Circle distance of 937 miles (or 1,509 kilometers).

A Great Circle is the shortest distance between 2 points on a sphere. Because most world maps are flat (but the Earth is round), the route of the shortest distance between 2 points on the Earth will often appear curved when viewed on a flat map, especially for long distances. If you were to simply draw a straight line on a flat map and measure a very long distance, it would likely be much further than if you were to lay a string between those two points on a globe. Because of the relatively short distance between Chan Gurney Municipal Airport and Lackland Air Force Base Joint Base San Antonio, the route shown on this map most likely still appears to be a straight line.
