The route
The great-circle path — the shortest line between the two airports across the curve of the earth. On a flat map it looks bent; on a globe it is straight.
Flight time at different cruise speeds
Aircraft type, winds and routing all move the real number. This is the same distance flown at different speeds, plus the 25-minute ground and climb allowance.
| Typical of | Cruise speed | Airborne | Gate to gate |
|---|---|---|---|
| Turboprop / regional | 550 km/h | 23h 49m | 24h 14m |
| Narrowbody jet (A320, 737) | 780 km/h | 16h 48m | 17h 13m |
| Widebody jet (777, 787, A350) | 900 km/h | 14h 33m | 14h 59m |
| Private jet (Gulfstream) | 850 km/h | 15h 25m | 15h 50m |
Headwinds on an eastbound long-haul routinely add 30–60 minutes; the same route westbound can be quicker. Airlines publish schedules with padding built in.

Questions
How long is the flight from Hong Kong to Dulles?
A non-stop flight from Hong Kong (HKG) to Dulles (IAD) takes about 16h 42m. The great-circle distance is 13,102 km (8,141 miles, 7,074 nautical miles), flying north on an initial bearing of 10°.
How far is Hong Kong from Dulles?
13,102 kilometres in a straight line over the earth's surface — 8,141 miles or 7,074 nautical miles. Actual flown distance is usually 2–5% longer because aircraft follow airways, avoid weather and route around restricted airspace.
Is there a non-stop flight between HKG and IAD?
This page calculates the direct-line time and distance; it does not track airline schedules. At 13,102 km the route is within reach of long-range widebodies, though not every city pair is served non-stop. Check an airline or booking site for what is actually scheduled.
What should I expect on a 16h 42m flight?
Anything past six hours is a long-haul flight: expect at least one meal service, a significant time-zone shift, and enough sitting that circulation and hydration start to matter. Cabin altitude, dry air and disrupted sleep do more damage to a training routine than the flight itself.
