If my memory serves me correctly, the APA contract now allows for domestic codesharing. If this is correct, I think that the APA should do everything possible to keep AA from selling Eagle. Once Eagle is sold, they could buy any size aircraft they wish and AA could still codeshare on them. All domestic flying, maintenance, dispatch, and ground handling would be done by Eagle. Sure, the stockholders, including top management, may like this, but it would do nothing to help AA employees, or Eagle employees who hope to one day make a living wage.
I have always thought that the APA needed to be more flexible in allowing RJs, but giving up 100 seat flying to Eagle, or any other entity, is not something I was hoping for.
AA management has a unique opportunity here. They have great flexibility in work rules, and the lowest wages they've seen in years. Hopefully they'll do the right thing.
