Since you brought me into this conversation...
I'm a Delta pilot (DOH 1987, flying as a 767ER capt.), and I was vehemently opposed to the USAirways buyout, but not for the reason you state. I saw the east guys as a group with unrealistic expectations, and an inability to honor their past agreements. You were unrealistic and unreasonable in your quest for date-of-hire integration, and when you didn't get your way, you chose to attempt an end run around the law.
At the time the USAirways/Delta attempt was announced, I was flying a trip with a SAN layover on Monday. Every Tuesday morning, I would ride to the airport with a US crew. Without fail, the F/O would ask me when I was hired, and if I could hold 777 captain (I could, and can, BTW). Their hunger and greed was palpable; they wanted what I had.
Just for a minute, though, lets ignore the personal aspect that makes any acquisition of USAirways assets so unappealing. What, exactly, would Delta (or United, or American, or Continental) need from your network to complete or enhance their own? Nothing, of course. All the above airlines have a comprehensive network already. None of these airlines need a new hub. We'd all like more restricted slots, but you know how the government is about those lately; they're more interested in giving them to jetBlue and Southwest.
For better or worse, you guys are stuck with each other. I hope you can make it work. I hope that the average east pilot doesn't share the attitude and viewpoint that I see on this board.
