when they joined bmi they kept their DOJ and their Sen, pres been set and it was BALPA that advised that it was the way that it had to be done; they cant say one thing to one airline and something different to the next.
Sorry to seem like an old grouch but when BA took over BCal the pilots took their seniority with them (Precedent set?) I was ready to lose my command and be the happiest 3-Striper on the Jumbo at LHR instead I was on the Rock and Roll. Once agian all overseen by that great arbiter of fair play BALPA!
My advice...............dont bank on anything!!!
