Let me throw my .02 cents in. I attend a school, that when I am done, I will have a AAS in aviation and at least a CFI. So, that being said, It will take about three years of teaching to be hired at a regional. Regionals do not require a four year degree. To upgrade to the majors, at best is a ten year proposition. With my current track, I will parlay my two degree into a four year degree with online schools. There is plenty of time in between to get that done. Remember the key to getting hired is flight hours, not necessarily your degree.
