- 60% of the services we sell on this corridor run through without a change. The remaining 40% involve one connection.
- How far it really runs
- The route covers 11,791 km against 11,447 km in a straight line, a detour of 3 percent. Track and road geometry account for the difference.
- Where the change is
- Connections are made at Columbus, Cincinnati, Chicago, Anchorage. The gap between arriving and leaving is 53 minutes, of which about 5 is walking.
- If the connection is missed
- The tightest connection we sell here has a 18 percent chance of not being made on the timetable alone. Part of this journey is a self transfer between separate tickets, so leave more time than the minimum and expect to check in again.
- First and last departure
- The first service of the day leaves Seoul at 06:08 and the last at 17:31, across 10 departures. The return direction keeps its own timetable, so the times back are not these times reversed.

Where these numbers come from
Observed service A carrier record shows this named operator serving this named pair, and we carry that through unchanged.
Schedules, seat counts and fares are generated by our own model until the supplier contracts are signed. Places, coordinates, operators, which operator serves which pair, and every distance are real. We would rather say that on every page than let a modeled number pass for a filed one.
