Or maybe on the other hand some of us F/Os would like a seniority list....would of perhaps stopped 21 GB F/Os politely stepping in front of me on the command list.
As far as I am aware for airlines with seniority lists, if you are good enough and your number comes up you get a go at a command course. If you are not good enough you will fail it, would certainly stop the less competant base captains seeking revenge on the F/Os that have p****d them off over the years ( and believe me we are talking about raising legitimate concerns over fuel decisions etc, and then the BC taking it personally and holding guys back!).
