JL is changing their flight time sfo-hnd from after midnight arriving 5am ish to leaving around 3pm and arriving 7 pmish. AA will NOT notify you , nor will JL! So if you're just flying to Japan it may be a small problem, but here's the gottcha If you are connecting JL does NOT change your connecting flight eg. I was supposed to arrive at 5am and leave at 11 am for a connection. The schedule change has me arriving at 7pm and leaving at 11 am THE SAME DAY (that is I am leaving BEFORE I ARRIVE), rather than changing to a legitimate connection or the next day flight (which means a forced overnight). Of course it gets worse if you are connecting further. AA will help if you call this to their attention, but I just discovered this accidentally when I was checking my trips prior to making hotel reservations.
