I guess you missed this part:"In fact the company does not even offer its non-union workforce regional pay."A proposal that is cost-neutral to the company has been brought up and rejected? In other words, the union has offered to forego a pay increase for (for example) TX/OK workers so that JFK workers could have an increase (or more of an increase), with no additional net cost to the company, and AA rejected it? I would like to see some proof for that assertion.
If you can back that up, I would agree with you that AA management is being rather shortsighted on the issue.
