I think Avro hit the nail on the head.

We have talked about this before but why is XJ hiring 80 new flight attendants? I know they have high attrition but for the month of May they had 92 lines of reserve for all three bases. I don't know what the staffing model is for flight attendants but it seems like hiring 80 more while you have 92 on reserve might be more then attrition.
