Nonstop flight route between Denver, Colorado, United States and Helena, Montana, United States:

About this route:

A direct, nonstop flight between Denver International Airport (DEN), Denver, Colorado, United States and Helena Regional Airport (HLN), Helena, Montana, United States would travel a Great Circle distance of 593 miles (or 955 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 Denver International Airport and Helena Regional Airport, the route shown on this map most likely still appears to be a straight line.

Facts about Denver International Airport (DEN):

• It was the fifth-busiest airport in the world by aircraft movements with over 635,000 movements in 2010.
• The system's $186 million original construction costs grew by $1 million per day during months of modifications and repairs.
• With the construction of DIA, Denver was determined to build an airport that could be easily expanded over the next 50 years to eliminate many of the problems that had plagued Stapleton International Airport.
• On September 25, 1994, the airport hosted a fly-in that drew several hundred general aviation aircraft, providing pilots with a unique opportunity to operate in and out of the new airport, and to wander around on foot looking at the ground-side facilities—including the baggage system, which was still under testing.
• Denver International Airport handled 52,556,359 passengers last year.
• Denver International Airport (DEN) has 6 runways.
• After the airport's runways were completed but before it opened, the airport used the codes.
