About this route:
A direct, nonstop flight between Tri-Cities Airport (PSC), Pasco, Washington, United States and Washington Dulles International Airport (IAD), Washington, D.C. / Virginia, United States would travel a Great Circle distance of 2,152 miles (or 3,463 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 Tri-Cities Airport and Washington Dulles International Airport, the route shown on this map most likely still appears to be a straight line.

- Since many major domestic and international airlines have a large presence at Washington Dulles, there are several airline lounges in active operation there.
- Conceived in early planning sessions in 1959, Dulles is one of the few remaining airports to use the mobile lounge for boarding and disembarkation from aircraft, and to transfer passengers between the midfield concourses and to and from the main terminal building.
- By the 1980s, the original design, which had mobile lounges meet each plane, was no longer well-suited to Dulles' role as a hub airport.
- Because of Washington Dulles International Airport's relatively low elevation of 313 feet, planes can take off or land at Washington Dulles 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.
