Don't get a woodie yet.... All 29 aircraft (including the DC10-30s) are showing on the S.365 filing, so they're not transferring anything to the parent company.
ILFC owns the 738's, and they probably have a waiting list of customers where they can place them. The other wildcard is WN. They're not showing up as an unsecured creditor, but I'd be surprised if their codeshare liability didn't put them on the list. Assuming an aircraft lease as settlement isn't out of the question, especially if ILFC already does business with WN.
The 757-200's are all at least 10 to 15 years old. Might be a good idea, or it might be a bunch of hangar queens once AA M&E has a chance to look over them... Looks like Boeing holds the paper on these.
The four 757-300's are oddballs that only a few airlines might be interested in. I don't see AA going with an unsupported small subfleet. They'll probably go to an existing operator (Condor, LTU, NW, CO).
But it would sure be nice for AA to grab a dozen 738's with winglets right now.
