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 | 26h 35m | 27h 00m |
| Narrowbody jet (A320, 737) | 780 km/h | 18h 44m | 19h 10m |
| Widebody jet (777, 787, A350) | 900 km/h | 16h 14m | 16h 40m |
| Private jet (Gulfstream) | 850 km/h | 17h 12m | 17h 37m |
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 Phoenix?
A non-stop flight from Singapore (SIN) to Phoenix (PHX) takes about 18h 35m. The great-circle distance is 14,617 km (9,082 miles, 7,892 nautical miles), flying north-east on an initial bearing of 41°.
How far is Singapore from Phoenix?
14,617 kilometres in a straight line over the earth's surface — 9,082 miles or 7,892 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 PHX?
This page calculates the direct-line time and distance; it does not track airline schedules. At 14,617 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 18h 35m 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.
