About this route:
A direct, nonstop flight between San Antonio International Airport (SAT), San Antonio, Texas, United States and Lemhi County Airport (SMN), Salmon, Idaho, United States would travel a Great Circle distance of 1,365 miles (or 2,197 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 San Antonio International Airport and Lemhi County Airport, the route shown on this map most likely still appears to be a straight line.

- Because of San Antonio International Airport's relatively low elevation of 809 feet, planes can take off or land at San Antonio International Airport at a lower air speed than at airports located at a higher elevation. This is because the air density is higher closer to sea level than it would otherwise be at higher elevations.
- Public transportation to and from the airport is provided by VIA Metropolitan Transit Authority's Route 5 bus.
- San Antonio International Airport was founded in 1941 when the City of San Antonio purchased 1,200 acres of undeveloped land that, at the time, were north of the city limits for a project to be called "San Antonio Municipal Airport." World War II Wartime needs meant the unfinished airport was pressed into federal government service.
- San Antonio closed the end of the 20th century with over 3.5 million passenger boardings in 1999.
