I'm toying with the idea of upgrading to NB Captain, coming off years of WB FO. I'm not sure I'd get an increase in pay, but the change of pace would be nice. The QOL is great on the WB stuff, but the flying is getting stale.
I figure if I look at upgrading like a prison sentence I'd be ok. Do it for the two year freeze to knock the rust off then go back to the WBFO position when it's up.
