How this is worked out
- Take both airports' published coordinates from OurAirports — nothing here is scraped from another flight site.
- Great-circle distance by haversine on a mean earth radius of 6,371.0088 km: 18,442 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 22h 55m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 23h 20m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
18,442 km / 805 km/h = 22h 55m airborne
+ 25 min ground = 23h 20m gate to gate

The same route, plotted on a world grid
The strip above gives the route its length and its shape. This gives it a position: latitude and longitude only, no coastlines, because a hand-drawn coastline would be decoration pretending to be data. On a flat grid the shortest path 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 | 33h 32m | 33h 57m |
| Narrowbody jet (A320, 737) | 780 km/h | 23h 39m | 24h 04m |
| Widebody jet (777, 787, A350) | 900 km/h | 20h 29m | 20h 55m |
| Private jet (Gulfstream) | 850 km/h | 21h 42m | 22h 07m |
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 this plate answers
How long is the flight from Buenos Aires (Ezeiza) to Hong Kong?
A non-stop flight from Buenos Aires (Ezeiza) (EZE) to Hong Kong (HKG) takes about 23h 20m. The great-circle distance is 18,442 km (11,459 miles, 9,958 nautical miles), flying south-east on an initial bearing of 150°.
How far is Buenos Aires (Ezeiza) from Hong Kong?
18,442 kilometres in a straight line over the earth's surface — 11,459 miles or 9,958 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 EZE and HKG?
This page calculates the direct-line time and distance; it does not track airline schedules. At 18,442 km the route is at the extreme end of what any airliner can fly non-stop, so a connection is likely. Check an airline or booking site for what is actually scheduled.
What should I expect on a 23h 20m 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.
