RAH has a hard-on for 170's. Mesa has gone all-in on the stretch CRJ concept. Seems like an odd pairing.

I like Mesa to contract some to a more manageable size, but don't see a buy-out or liquidation in the next couple years. Long term prospects are cloudy, but that's the case for most regionals - the massive growth is over. There's just not much of a demand for 50 seat jets and smaller turbo-props in the US market, and mainline carrier's pilot groups have figured out that capturing the smaller gauge flying through scope is a required item in negotiations, so the instance of contract flying of smaller gauge 'replacing' mainline's larger gauge are dwindling.

My crystal ball is on the fritz today though, so I'm just speculating as much as the next guy.
