UPGRADES???
I can tell you that refusing an upgrade WILL result in your being fired.(immediately lost confidence in you)!so please stop referring to it as some kind of choice. There are a considerable number of loud mouth idiots on this forum who know nothing of the history or issues of this decade long dispute.There is a collective effort to have CX honour its contract and to resolve the disgusting manner in which the 49'ers were fired.Having an individual take the full weight of the current management's wrath alone would achieve nothing and be professional suicide....fact!
Incidentally the 'B' scale captains you refer to are freighter crew or CX mainstream f/o's who upgraded to capt. on the freighter on less pay than the f/o slot he left behind!
If you rely on this site to embellish you with the facts you will be doomed to be the 'eternal moron'.
