Pure speculation, but here it goes:

The Delta RFP would only have any real impact on three of their carriers: RAH, Mesa, and Comair. ASA/SKW are already under contract and none of their flying was up for grabs in this RFP. That doesn't mean they can't pick up extra flying, but they won't lose any either. The way I see it, this whole RFP was more of a management tactic towards Comair pilots during contract negotiations than anything else. Comair is a much more valuable asset left in tact then it would be if Delta simply moved their flying to some other carrier and dropped the company piece by piece. I also know that RAH did not bid for any CRJ flying (as stated by our CEO) so we're not going to "take" any of it. I guess that just leaves Mesa.

If I had to hazard a guess, I would speculate that you might see a minor shift in some flying (i.e. SKW getting 12 CRJ-700's) but no company is going to pick up the bulk of those 143 aircraft. When the dust settles, everyone will probably be doing the same amount of flying as they were before.

In a perfect world, RAH could get back all the flying it lost to Freedom out of MCO and my QOL would increase exponentially...but you know what they say about "want in one hand..."

Edit - If you see 10 145 XR's in SLC with "Operated by ExpressJet" on the side...my entire theory is null and void. However, I think that rumor is more of a cruel joke. Imagine the irony of SKW pilots complaining that XJT stole their flying
