Look, Spirit has been great to all of us and many have been lucky enough to call this place home for a long time. Now that the merger was denied (crazy, I know) and an appeal is a longshot, it comes down to whether or not you see a path forward for Spirit. Those that do are staying put, conversely, those that do not are applying elsewhere. I believe it's that simple. Nobody knows how it'll all work out. You just have to take a look around, make a decision on what is best for your personal situation and take action (or not).
