On occasion, Haruka will be 10-15 minutes late pulling into KIX station; usually it's not a problem for international travelers, since they're planning to arrive 2 hours early, but some friends and I have had to sprint from the station to make our domestic flights.

Every once in a blue moon, Haruka is over 30 minutes late. Usually it has to do with someone on the tracks, so the entire schedule goes out the window. The problem is compounded with the fact that Haruka shares tracks for most of its route.

Once, all Haruka trains were canceled because a signal at Tennoji caught on fire and they had to shut down the entire line.
