maybe simplistic but true.
Look at LGW from an outsider they have nothing I want let alone LHR crew want so why fight for something that doesn't help them? same principle.
Very simplistic argument to say what I said about long haul, but if it doesn't benefit LHR crew, then no one inside the that little bubble cares what happens.. as it stands LHR pilots want a slice of the action(quicker promotion etc...) so now they are fighting...
