Nonstop flight route between Houston, Texas, United States and Cahokia, Illinois (near St. Louis), United States:

About this route:

A direct, nonstop flight between George Bush Intercontinental Airport (IAH), Houston, Texas, United States and St. Louis Downtown Airport (CPS), Cahokia, Illinois (near St. Louis), United States would travel a Great Circle distance of 663 miles (or 1,067 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 George Bush Intercontinental Airport and St. Louis Downtown Airport, the route shown on this map most likely still appears to be a straight line.
