This is not scientific at all, and could be completely wrong, but a little anecdotal experience I have had. A couple years ago when SKW was moving into ORD hard and there were more skw planes at the g gates than eagle, I logged into jetnet and researched routes. No matter what, greater than 60 days out it always showed as operated by Skywest. Even on eagle heavy routes to heavy mx bases and everything. But then I noticed within a two month window they would they switch to envoy. I didn't research too much, just tucked that random information away in my brain for no reason whatsoever and never took much stock on what it says too far out on the travel planner. So who knows. But I would definitely be bummed if Mesa got those routes. I mean DSM and GRR are amazingly scenic and bustling centers of tourism for sure, so it would be hard to give up a wonderful experience at the crown plaza grr, but i wouldn't mind a SLO overnight
