Entaxei,
Firstly, LCY crew are not part of Mainline BA but Cityflier so the strike didn't include them at all.
There are only about 150 Unite members left at LGW (estimate).
I think LGW crew (myself included) need a specific LGW union type organisation, whether an actual union or works council or whatever.
I'm all for getting rid of Bassa, as they've done nothing but tarnish our reputation in the last (however many) years.
