A perceived stinginess among management and a very underwhelming reception to "the new American." I think the payrates will be lower than United and Delta's too. Parker might've been better than Smisek, but I'd rather negotiate with Munoz or Anderson in the future.
I could be wrong on this or have an outdated perception, but I think UAL/DAL have more widebody jobs too.
But that being said, yes, most guys would still happily accept a class date at AA.
