I flew full time for a 135 outfit while in college, while pursuing - and eventually obtaining - an aeronautical engineering degree. I eventually drifted out of flying professionally for awhile, and ended up in another career altogether. BUT, I know that it would have been very difficult for me to land an aeronautical engineering job after being out of that field for a few years. If you enjoy chemistry, I would pursue that. Maybe even chemical engineering? I think you will always be better off in a field that you enjoy studying, rather than trying to "fit" yourself into another person's perception of what a good college major might be.
