I think regardless of long term strategy or who may be "partially owned but wholly controlled" or any other considerations like performance or cost, in the end the key is who has the pilots to fly them. XJT clearly does not. Sadly, this favors the airline who is willing to over hire in the short term and let pilots sit reserve with little flying while they wait for the airplane award.

So Compass has (or did have, people are bailing) 30 airplanes worth of E175 CAs and FOs. Timing might be a little off, but it seems like too good a match to pass up. But who knows what sorts of deals are being discussed. Probably everything imaginable has been proposed by someone somewhere. It'll be interesting to see what shakes out.
