The rumors are definitely flying fast and furious. I just heard one about a merger with ExpressJet. I don't hold this rumor to be any more credible than any of the rest, and probably very unlikely to be true.
I do think it's definitely entertaining to hear all the crazy stuff that gets passed around. New -900s, possible mergers, possible liquidations of other carriers (wholly owned or not) and acquisition of their assets, etc. etc.
No one should get too excited. IMO something is afoot, but I'm not sure what it is and am not going to get too concerned about it. And if nothing happens by the end of the year then watch morale sink.
So for anyone who thinks ASA, ahem, Atlantic Southeast pilots are crazy to be passing on these rumors, just take a chill pill. We'll all believe it when we see it. For now it's just idle entertainment.
