Glamgirl,
Unfortunately it has always been like that and it really makes me sad. Some crew at LHR are going on about getting support and sympathy from LGW because our T&C's have to be defended before it will also affect them (!).
I'm based at LHR and this is an ongoing discussion on almost every flight and every single time I have been shouted down whenever I have asked them why the crew at LGW should care because nobody was there for them when they had their T&C's changed! LHR couldn't have cared less as it was none of their business and nobody "would dream of transferring to LGW"!
