The most difficult step in an pilots career is to get from that turboprop onto a jet. Took some time to get that change. Grab it with both hands, if you want to end your career flying jets and in the end want to improve your salary.
Lets face it , the money is been made on the jet fleet, not on the props. I can also confirm that nobody gives a rats if you where captain/tri/chief pilot on an turbo prop, just does not count (how sad indeed).
On the other hand you must really like your lifestyle now as 99% of the guys wouldn,t even ask this question. If thats more important to you than future income increase, stay where you are!
