It definitely doesn’t happen overnight. Many of those who can hold a junior line as a WB captain would take a pay cut, fly the worst trips, and give up control of their schedules to upgrade. It’s not really worth it. Until that day, life as a WB first officer is a great gig if you can handle the fatigue issue. The difference between flying 12 days a month as a WBFO and 15 a month as a NBCA is only around $40K. I’m staying on the NB only due to the fact that I can’t handle the fatigue. I feel much better and maintain a healthy lifestyle keeping regular hours and sleeping in a bed every night, but the extra days on the road, increased workload, and hassle of NB flying definitely isn’t worth the few extra dollars. I’m glad that we have options here that allow people to find out what works for them.
