On August 31, AA flew a non-ETOPS A321S (N137AA) from LAX to HNL as AA31. Discovered once the plane had passed the halfway point, so too late to turn back. Return flight HNL-LAX (AA162) cancelled, plane ferried back to LAX.

Many people failed to do their job properly for this to happen - dispatch, pilots, etc. I suspect the pilots will shoulder most of the blame.
Fleet standardization has its advantages.
