As a Mesa guy, this seems plausible at least from our end.
Since I've been here (nearly 2 years) I have heard that SKW would love to get their hands on our flying as it would give them a huge market share of UA flying, and another chunk of Delta.
God knows SKW has the $, our stock was down almost a quarter today, to $3 and change.
I just hope it wouldn't adversely affect those of us on the cusp of upgrade.
What I ride it could, and will be.
