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 | 29h 50m | 30h 15m |
| Narrowbody jet (A320, 737) | 780 km/h | 21h 02m | 21h 28m |
| Widebody jet (777, 787, A350) | 900 km/h | 18h 14m | 18h 39m |
| Private jet (Gulfstream) | 850 km/h | 19h 18m | 19h 44m |
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 Santiago to Singapore?
A non-stop flight from Santiago (SCL) to Singapore (SIN) takes about 20h 48m. The great-circle distance is 16,411 km (10,197 miles, 8,861 nautical miles), flying south on an initial bearing of 170°.
How far is Santiago from Singapore?
16,411 kilometres in a straight line over the earth's surface — 10,197 miles or 8,861 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 SCL and SIN?
This page calculates the direct-line time and distance; it does not track airline schedules. At 16,411 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 20h 48m 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.
