AA becomes a fire sale giving the creditors the best deal. AA is then piecemealed out for routes only SANS the employees.
There's another possibility that hasn't been mentioned much, Hopeful... You guys have long been worried about being owned by BA. Maybe it's time to start wondering about being owned by a sheik.
Your fire sale has probably a < 5% possibility, mainly because parting out AA would probably not yield as much as it did for Pan Am or Eastern.
Routes themselves have no value. Most international airport employees work thru ground handling companies. With all of the open skies treaties signed in the past 20 years, any airline can pretty much fly anywhere if they want, with few exceptions. There might be a few slots that could be sold, and AA has a few owned airplanes that might have some value. But the rest would be dispersed.
There are really just two non-employee assets AA has right now that have any meaningful value right now -- AAdvantage, and the JV's with oneworld partners. DL and UA know that there's no way the JV's would survive a transfer of ownership to either of them, and just about everyone of any value who belongs to AAdvantage also belongs to SkyMiles or MileagePlus.
But those two non-employee assets do hold value once you look outside of DL and UA. I've pondered whether or not WN would take a quantum leap and invest in AA, and the news this week that Emirates was considering investment in the US and India could also be a possibility. They don't care about being limited to a 25% control status if it would solidify their footprint.
