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 | 21h 25m | 21h 50m |
| Narrowbody jet (A320, 737) | 780 km/h | 15h 06m | 15h 31m |
| Widebody jet (777, 787, A350) | 900 km/h | 13h 05m | 13h 30m |
| Private jet (Gulfstream) | 850 km/h | 13h 51m | 14h 17m |
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 Porto to Singapore?
A non-stop flight from Porto (OPO) to Singapore (SIN) takes about 15h 03m. The great-circle distance is 11,777 km (7,318 miles, 6,359 nautical miles), flying east on an initial bearing of 74°.
How far is Porto from Singapore?
11,777 kilometres in a straight line over the earth's surface — 7,318 miles or 6,359 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 OPO and SIN?
This page calculates the direct-line time and distance; it does not track airline schedules. At 11,777 km the route is within reach of long-range widebodies, though not every city pair is served non-stop. Check an airline or booking site for what is actually scheduled.
What should I expect on a 15h 03m 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.
