About this route:
A direct, nonstop flight between Ponciano Arriaga International Airport (SLP), San Luis Potosí, San Luis Potosí, México and Castle Airport (MER), Atwater, California, United States would travel a Great Circle distance of 1,568 miles (or 2,523 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 Ponciano Arriaga International Airport and Castle Airport, the route shown on this map most likely still appears to be a straight line.

- Because of Castle Airport's relatively low elevation of 191 feet, planes can take off or land at Castle 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.
- Castle Airport (MER) currently has only 1 runway.
