Nonstop flight route between Salt Lake City, Utah, United States and St. Mary's, Alaska, United States:

About this route:

A direct, nonstop flight between Salt Lake City International Airport (SLC), Salt Lake City, Utah, United States and St. Mary's Airport (KSM), St. Mary's, Alaska, United States would travel a Great Circle distance of 2,555 miles (or 4,112 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 large distance between Salt Lake City International Airport and St. Mary's Airport, the route shown on this map most likely appears curved because of this reason.

Try it at home! Get a globe and tightly lay a string between Salt Lake City International Airport and St. Mary's Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Salt Lake City International Airport (SLC):

• A new terminal was needed and work began on the west side of the airport on Terminal 1, designed by Brazier Montmorency Hayes & Talbot and dedicated in 1960 after seven years of work and a cost of $8 million.
• Because of Salt Lake City International Airport's high elevation of 4,227 feet, planes must typically fly at a faster airspeed in order to takeoff or land at SLC. Combined with a high temperature, this could make SLC a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
• Salt Lake City International Airport handled 20,102,078 passengers last year.
• Wingpointe, an 18 hole golf course, is located on the south end of the airport.
• Delta Air Lines and Frontier Airlines have scheduled flights to cities in Canada, Mexico, and France.
