When a connection carrier successfully gets ALPA to negotiate a contract with Delta Air Lines(Or other ALPA major airline), that binds a major and or DAL not the holding company but Delta Air Lines to this feeders contract (CBA)and calls the flying theirs, I will be concerned. Until then I have not seen a case where a ALPA regional that does contracted lift has 1) Gone for and 2) Successfully bound a major airline to the flying they perform.
Currently that is a function of contracts that one airline and or holding company has with another for flying that is "allowed" by another mainline contract.
