About this route:
A direct, nonstop flight between LA/Ontario International Airport (ONT), Ontario (near Los Angeles), California, United States and Lemhi County Airport (SMN), Salmon, Idaho, United States would travel a Great Circle distance of 790 miles (or 1,271 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 LA/Ontario International Airport and Lemhi County Airport, the route shown on this map most likely still appears to be a straight line.

Facts about LA/Ontario International Airport (ONT):
- LA/Ontario International Airport handled 4,812,006 passengers last year.
- In 1946, the Ontario Municipal Airport was renamed the "Ontario International Airport" because of the transpacific cargo flights originating from the facility.
- LA/Ontario has few noise restrictions/abatement rules, unlike other Southern California airports such as John Wayne Airport, Bob Hope Airport, Long Beach Airport, and San Diego International Airport, which all have very strict policies.
- LA/Ontario International Airport (ONT) has 2 runways.
- Because of LA/Ontario International Airport's relatively low elevation of 944 feet, planes can take off or land at LA/Ontario 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.
- The furthest airport from LA/Ontario International Airport (ONT) is Pierrefonds Airport (ZSE), which is located 11,460 miles (18,443 kilometers) away in Saint-Pierre, Réunion.
- The closest airport to LA/Ontario International Airport (ONT) is Chino Airport (CNO), which is located only 6 miles (10 kilometers) SSW of ONT.
Facts about Lemhi County Airport (SMN):
- Lemhi County Airport (SMN) currently has only 1 runway.
- The furthest airport from Lemhi County Airport (SMN) is Tôlanaro Airport (FTU), which is located 10,686 miles (17,197 kilometers) away in Tôlanaro, Madagascar.
- Because of Lemhi County Airport's high elevation of 4,043 feet, planes must typically fly at a faster airspeed in order to takeoff or land at SMN. Combined with a high temperature, this could make SMN a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
- The closest airport to Lemhi County Airport (SMN) is Challis Airport (CHL), which is located 45 miles (72 kilometers) SSW of SMN.
