I don't think so. Given the size of the Eagle operation, I doubt they could sell it off in one piece. It would probably have to be sold in sections, roughly one for each aircraft type (CRJs, ERJs, Saabs, ATRs, etc.)
Remember, it wasn't too long ago that Eagle consolidated its operations buy purchasing the Eagle carriers. Now, the only independent airlines in the AA
system are the Connection carriers that came with the TWA acquisition.
Given the rise of RJs on previously mainline routes (DFW
, etc.), Eagle is probably responsible for too much AMR revenue for them to spin it off.
