Maybe lack of sleep is the underlying reason for Parker's appearance. I doubt he sleeps very well with all that is going on in his personal life (DUI and the unending scrutiny it has spawned, possibly still battling the bottle...and these are the things that we know about,) and what is going on with the airline. He's likely nervous that the consolidation will start and end without him. Not that he's worried what will happen to USAirways (and its employees,) but that he will not be able to either cash out big time or become CEO of a major industry player. The fact that the unions are being very resistant to accepting joint contracts will very effectively keep him out of the consolidation game, and that, no doubt, scares the bejeezus out of him.
