SKW is precluded by scope from flying them for DL or UA.

I doubt they are going to midwest...that market appears locked up by RAH, and they are on weak financial footing. SGU would not buy 16 large airplanes for a crapshoot like that.

I would think they would go to a major. However...I can't imagine of why a major would keep an airplane order a secret. That leads me to suspect they might be going to a regional...or maybe a major which will then outsource their operation..
