From my experiences at Fly I the planes will generally go to company maintenance first to make sure all MELs are fixed and that the aircraft is ready to go back to the lessor unless the company shuts down and there are no mechanics to inspect them. I don't know how the Qs and 900s are financed, but at Fly I the CRJs were leased through several different banks and most will want the original engines back on the aircraft. Some had company pilots ferry them to storage locations and some had their own pilots come to the maintenance hangar at Dulles to ferry them.

When Fly I was negotiating the return of some of the CRJs there was one that was leased to the company by an individual. The story goes that he was being an SOB (course I might be an SOB if Tom and Kerry called and said they were sticking me with an airplane) and demanded the original engines, etc. When he showed up at the hangar in Dulles the CRJ was sitting there with two crated engines, and he was told to get the engines mounted on his own. Needless to say he wasn't happy but finally had his pilots ferry the aircraft out after getting the engines mounted.

Hopefully the company will have an announcement soon so employees can properly plan their futures. Rumors will spiral out of control anyway, but it would be nice to have some solid information.
