Nonstop flight route between Denver, Colorado, United States and Belfast, Northern Ireland, United Kingdom:

About this route:

A direct, nonstop flight between Denver International Airport (DEN), Denver, Colorado, United States and Belfast International Airport (BFS), Belfast, Northern Ireland, United Kingdom would travel a Great Circle distance of 4,337 miles (or 6,980 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 Denver International Airport and Belfast International 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 Denver International Airport and Belfast International Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Denver International Airport (DEN):

• Denver International Airport handled 52,556,359 passengers last year.
• 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.
• From 1980 to 1983, the Denver Regional Council of Governments investigated six areas for a new metro area airport which were north and east of Denver.
• Because of Denver International Airport's high elevation of 5,431 feet, planes must typically fly at a faster airspeed in order to takeoff or land at DEN. Combined with a high temperature, this could make DEN a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
• The midfield concourses allow passengers to be screened in a central location efficiently and then transported via a rail system to three different passenger concourses.
• The system's $186 million original construction costs grew by $1 million per day during months of modifications and repairs.
