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 42m | 24h 07m |
| Narrowbody jet (A320, 737) | 780 km/h | 16h 43m | 17h 08m |
| Widebody jet (777, 787, A350) | 900 km/h | 14h 29m | 14h 54m |
| Private jet (Gulfstream) | 850 km/h | 15h 20m | 15h 45m |
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 Philadelphia?
A non-stop flight from Hong Kong (HKG) to Philadelphia (PHL) takes about 16h 37m. The great-circle distance is 13,036 km (8,100 miles, 7,039 nautical miles), flying north on an initial bearing of 8°.
How far is Hong Kong from Philadelphia?
13,036 kilometres in a straight line over the earth's surface — 8,100 miles or 7,039 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 PHL?
This page calculates the direct-line time and distance; it does not track airline schedules. At 13,036 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 37m 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.
