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 | 28h 12m | 28h 37m |
| Narrowbody jet (A320, 737) | 780 km/h | 19h 53m | 20h 18m |
| Widebody jet (777, 787, A350) | 900 km/h | 17h 14m | 17h 39m |
| Private jet (Gulfstream) | 850 km/h | 18h 15m | 18h 40m |
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 Baltimore?
A non-stop flight from Singapore (SIN) to Baltimore (BWI) takes about 19h 41m. The great-circle distance is 15,508 km (9,636 miles, 8,374 nautical miles), flying north on an initial bearing of 1°.
How far is Singapore from Baltimore?
15,508 kilometres in a straight line over the earth's surface — 9,636 miles or 8,374 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 BWI?
This page calculates the direct-line time and distance; it does not track airline schedules. At 15,508 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 41m 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.
