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 | 27h 29m | 27h 54m |
| Narrowbody jet (A320, 737) | 780 km/h | 19h 23m | 19h 48m |
| Widebody jet (777, 787, A350) | 900 km/h | 16h 48m | 17h 13m |
| Private jet (Gulfstream) | 850 km/h | 17h 47m | 18h 12m |
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 Detroit to Singapore?
A non-stop flight from Detroit (DTW) to Singapore (SIN) takes about 19h 12m. The great-circle distance is 15,115 km (9,392 miles, 8,161 nautical miles), flying north on an initial bearing of 349°.
How far is Detroit from Singapore?
15,115 kilometres in a straight line over the earth's surface — 9,392 miles or 8,161 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 DTW and SIN?
This page calculates the direct-line time and distance; it does not track airline schedules. At 15,115 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 19h 12m 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.
