I was at LAX yesterday and couldn't help but notice a really bad run for the Hawaii flights:
LAX-HNL:
AA/2726 scheduled 11:35am, actual 5:28pm
AA/297 scheduled 5pm, showing cancelled (but also listed as 7am, so maybe an overnight mechanical that ultimately cancelled?)
AA/109 scheduled 7:45pm, actual 9:10pm
LAX-OGG:
AA/271 scheduled 10:45am, actual 5:01pm
LAX-KOA:
AA/59 scheduled 10:50am, actual 11:58am
Most of those are A321s
