Nonstop flight route between Hanoi, Vietnam and Denver, Colorado, United States:

About this route:

A direct, nonstop flight between Nội Bài International Airport (HAN), Hanoi, Vietnam and Denver International Airport (DEN), Denver, Colorado, United States would travel a Great Circle distance of 7,781 miles (or 12,523 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 large distance between Nội Bài International Airport and Denver 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 Nội Bài International Airport and Denver International Airport. You'll see that it will travel the same route of the red line on this map!

• Because of Nội Bài International Airport's relatively low elevation of 39 feet, planes can take off or land at Nội Bài 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.
• In 2010, the airport received approximately 9.5 million passengers, which made it overloaded, and accounted for one-third of international departures and arrivals at Vietnam's three international airports.
