Not adjusting regional pay scales, at least for American ($864 million Q2 profit), is going to be hard to justify. Something as simple as eliminating 1st year pay, and adding more a/c is hardly going to negate the justification of a regional B scale.
Not to mention the revenue they stand to loose shutting down Envoy which is what would happen if they fail to entice new hires. I see brighter days ahead for Envoy.
