Gees, I feel for ya man (woman?). I am surprised to hear this from Air Wis....I would think a couple other regionals have one foot in the grave and the other on a banana peel more so than Air Whiskey does.
IF you are going to move laterally, and IF you like Endeavor's bases, you might at least give Endeavor a look based on things like good regional first year FO pay, and reasonable upgrade time, plus guaranteed interview at Delta. But if you like Commute Air or PDT's career progression to mainline better, by all means go there.
