You may not have caught my sarcasm.
Parker never had to file for Ch 11 as HP had already done that years before he took over. He was handed US Airways in 2005 as it exited from its second bankruptcy. Parker didn't have to file for Ch 11 because the combined HP/US had very low payrates and very low labor costs compared to AA.
AA didn't "go bankrupt" in the typical sense. Unlike most debtors, AA had no shortage of money to borrow.
AA filed for Ch 11 primarily to drive a stake thru the heart of labor and the lingering cries of "Restore and More." AA's pilots and FAs wanted gains from 2008 until 2011 and AA was unwilling to hand out any gains.
My point to the US cheerleader is that there's a constant drumbeat that AA "went bankrupt" and thus that must be proof that every decision of prior AA management was sub-optimal. Now, the new sheriff, Parker and his sidekick Kirby, are announcing all sorts of "changes" that are meant to deflect any critique of the poor management of US Airways.
