How far is Hong Kong from Buenos Aires (Ezeiza)?
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 HKG and EZE?
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.
