About this route:
A direct, nonstop flight between Walla Walla Regional AirportWalla Walla Army Air Base (ALW), Walla Walla, Washington, United States and Portsmouth International Airport at Pease (PSM), Portsmouth, New Hampshire, United States would travel a Great Circle distance of 2,310 miles (or 3,718 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 Walla Walla Regional AirportWalla Walla Army Air Base and Portsmouth International Airport at Pease, the route shown on this map most likely still appears to be a straight line.
