AA doesn't want them anymore, they have their own el cheapo place (PSA) they can place them, and AWAC is taking a pretty big hit to the bottom line if they use the extension.

DAL is also losing a lot of 50's, the CHQ and PCL airframes to name a view. I'd be surprised if it's additional growth at this point however.

Seems like it would just be a lot easier to throw them on the ASA side of the house.
