No, I'm not privy to any inside info about whether AMR was actually going to file in 2003, but if you read my posts (#3 and #13) carrefully, you'll see that neither requires an assumption that AA was actually going to file. All you have to believe is that AA would have sought and would have obtained deeper concessions in pay and benefit cuts had it filed. AA made no secret in 2003 that the Vermont Plan would have cost the employees more than the 2003 concessions did. The OP said that the employees would have been better off had AA filed in 2003 because AA would not be facing bankruptcy now. It's that faulty premise with which I disagree.
There was a common emotion expressed in this forum in early 2003 and repeated every so often that the 2003 bankruptcy discussions were an empty threat and that employees should have called Arpey's bluff, because he lacked the stones to actually file. Bob Owens made much of the fact that they were lying about being on the courthouse steps because the courthouse in NYC has no steps. The phrase "courthouse steps" is used even when courthouses lack steps, but Owens seized on that as more lies from management. Well, today the board proved that it is not afraid of bankruptcy, and it's a given that the company will seek (and will probably get) pay and benefit concessions again.
On the one hand, the OP and others claim that it was AA's huge concessions that set the bar, forcing the others to demand even greater concessions - Bob Owens has posted this belief repeatedly. Well, if he's right, then a 2003 AMR bankruptcy would have set the bar even lower, which would have forced the others to cut pay and benefits even further. Had UA, US, NW and DL obtained even bigger concessions, it's my belief that AA would be in the same mess today - with costs that exceed its major competition.
I'm sure there are still chest-thumpers who will claim in the coming days and weeks that no concessions will be forthcoming, but IMO, they're delusional.
