I guess I'm not following. What options?

FedEx has pilots hired into every seat (at least they did when they were hiring), so a junior pilot could stay a widebody FO or make a little more flying the left seat of the narrow-body. Or, stay senior on the junior airplane. I saw dudes that were below 50% seniority in the right seat still on probation.

I was activated in the left seat at 26 months on property. Until I could hold widebody captain at around 4-5 years, I made more money than I would have if I had stayed a widebody FO.
