So you’re thinking of commuting to a Frontier base vs. living in a large Jetblue base, for an extra $50-$60/hr while you’re commuting to Reserve as a F9 Captain. That pay advantage between F9 Captain and Jetblue FO would only last 2-3 years, then it swings the other direction. Plus you have to consider the sizeable difference in first year pay between the two and the advantages of driving to work.
