As long as we’re comparing regionals to regionals, majors to majors, legacies to legacies:
Living in base is everything. Nothing else is going to trump that. You live in Miami? Work for an airline with a base in Miami. Bid for the airplane that will get you based in Miami even if you’ll have to commute short term somewhere else.
That said. Envoy’s Miami base is really small (and senior last I checked). I’m not sure Envoy is the best place if you need a Miami base. I don’t fully know Miami situation well because I don’t need to, but I have to think there’s a better option there.
