Hmmm..
You're pissed about DEFO pax but not freight. So this is really about money and not flying then? I don't really believe that. I think you're pissed beacause your seniority can hold FO, but CX decided not to "let" you progress and has instead hired a DEFO pax. Should I be pissed that the guy hired the day before my three years is senior to me for the PAX bid?
I think your problem is with CX, not the DEFO. I am accepting that I may never make it any further at CX then what they hire me as. Again, that is the reason that I did not apply to be an SO.
How about the union getting a contract that no longer allows bypassing seniority for career progression instead of infighting? You know, be a part of the solution instead of being a part of the problem.
