I doubt you will lose your chiefs. US Airways has 2 regional airlines. Both have their own Presidents and Vice Pres. Parker doesn't have the time or energy to manage the wholly owned regionals. My prediction is that there will be a merger of Airways and American. Then there will be three regionals under the umbrella.
But.....
From what i hear the Mainline Airways pilots have a combined seniority list that includes PSA/Piedmont pilots. I assume to bring the number of mainline pilots at airways look higher. There has always been rumors of a flow thru from the wholly ownes to mainline but nothing ever became of it.
Parker can run a better airline that Horton. And don't flatter yourself too much. American does have some nice airplanes but you are plagued with some stale old crusty f/a's and gate agents like airways. Personally after reading the non-rev travel for express carriers, Airways system is much better.
