As a Cityflier pilot , and BALPA member I fully support the mainline stand against Open Skies, but i have to believe that the precident may have allready been set.
Cityflier are flying BA aircraft , Wearing BA uniform and providing the BA product day in day out on lower T&C's.
When we were created from the division and sale of Connect, The BACC refused to apply the same principals as you wish to do now, as we were classed as not suitable to be part of mainline BA.
I personally feel that this decision may come back to haunt the BACC, Scope clause or not!
Good luck to you all if it does go to the wire !!!!!
