Just to be clear, I have never implied that leaving JB for a regional was a good idea. In fact, leaving a regional for ANYWHERE that YOUR airline's name is on the ticket is a good idea.
I was just responding to those who say JB is far an above a regional when it comes to pay and QOL. That may not be quite so true, and is something to consider as one is planning to make a career move.
I would further state that even with a pay cut, going from a regional to JB or any other major is a smart move. 2-3 years down the road, you'll be glad you did, I am sure.
I simply posted those numbers (using the lower paying acft at both B6 and 9E) to show how small the pay gap has become. Fingers crossed for you to get that CBA sooner rather than later!
