"Of course the major flaw in that argument is that pilots tend to be bound by seniority systems across the industry which makes it extremely difficult to migrate to another operator unless you are prepared to commit to them for 10+ years."
Been reading this thread from the start, and understood that it wasn't about T's and C's, that is already agreed with Balpa This dispute is more about forcing BA to put Open Skies pilots onto the BA senority list from what i understand?
Take it from your quoted comment above Hand Solo that you think it is seniority lists that make it more difficult for pilots to move, so why fight to have more people on a seniority list?
