without a doubt on all points. as far as the L4-L8 from my point of view there is absolutely none capable on the bench or the batters circle.I wouldn't get too wrapped up in it. Who the CEO or President or VP is doesn't really impact the day to day work. The people making those dumb decisions are all planted at L4 thru L8. Who their boss's boss's boss is won't change that.
What a new CEO would do is perhaps improve standing with investors and banks. The financial hole and prospects for coming out of it are hardly impressive compared to where UA and DL are right now. AA's a bloated whale gasping for air and trying not to wind up on the beach.
