Nonstop flight route between between Baltimore, Maryland and Washington, D.C., United States and Zhoushan, Zhejiang, China:

About this route:

A direct, nonstop flight between Baltimore/Washington International Thurgood Marshall Airport (BWI), between Baltimore, Maryland and Washington, D.C., United States and Zhoushan Putuoshan Airport (HSN), Zhoushan, Zhejiang, China would travel a Great Circle distance of 7,507 miles (or 12,082 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 Baltimore/Washington International Thurgood Marshall Airport and Zhoushan Putuoshan 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 Baltimore/Washington International Thurgood Marshall Airport and Zhoushan Putuoshan Airport. You'll see that it will travel the same route of the red line on this map!
