According to flightstats, KE74 today (Mar 9) is scheduled to arrive more than two hours late: http://www.flightstats.com/go/Flight...03-09&x=20&y=3.

What seems to be puzzling to me is the fact that the flight left YYZ a few minutes ahead of schedule but is estimated to arrive ICN 5:09pm, 2h 9min behind schedule. Doesn't look like the flight is being diverted or making a tech stop anywhere. I'm not an aviation tech expert so I'm curious as to why there is such lengthy delay?
