Just food for thought, there are probably enough young guys around now who don't remember, but ExpressJet, the company, used to be properly known as "Continental Express" when it was wholly owned by Continental and had to change its name when it was spun off from CAL in the early 2000's. Similar situation when ASA was spun off from Delta. Nearly a decade of ups and downs followed to get to where we are now. Read the Eagle situation carefully as it appears to be setting up for a repeat of the XJT spin-off if AMR simply spins Eagle off without selling it to a healthy Holding company and drops the "American" from Eagle, or gets some other generic company name.
With all that said, still a crapshoot.
