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 22m | 27h 47m |
| Narrowbody jet (A320, 737) | 780 km/h | 19h 18m | 19h 43m |
| Widebody jet (777, 787, A350) | 900 km/h | 16h 43m | 17h 09m |
| Private jet (Gulfstream) | 850 km/h | 17h 42m | 18h 08m |
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 Singapore to Chicago?
A non-stop flight from Singapore (SIN) to Chicago (ORD) takes about 19h 07m. The great-circle distance is 15,051 km (9,352 miles, 8,127 nautical miles), flying north on an initial bearing of 13°.
How far is Singapore from Chicago?
15,051 kilometres in a straight line over the earth's surface — 9,352 miles or 8,127 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 SIN and ORD?
This page calculates the direct-line time and distance; it does not track airline schedules. At 15,051 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 07m 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.
