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.

Questions

How long is the flight from Porto to Seoul?

A non-stop flight from Porto (OPO) to Seoul (ICN) takes about 13h 01m. The great-circle distance is 10,147 km (6,305 miles, 5,479 nautical miles), flying north-east on an initial bearing of 34°.

How far is Porto from Seoul?

10,147 kilometres in a straight line over the earth's surface — 6,305 miles or 5,479 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 ICN?

This page calculates the direct-line time and distance; it does not track airline schedules. At 10,147 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 13h 01m 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.
