Was a WB CA for an international legacy, now flying NB FO with guys younger and less experience than myself. Does it bother me? Not one bit. I took the pay cut (which after year 3, became a pay rise), flew reserve for a few months, commuted for a few months, and can hold NB CA in almost every base. It quickly becomes a distant memory.
None of us are getting out of here alive, in the end, the money race is with ourselves
Good luck!
