I agree, I've gone to the top about an issue like this and been surprised how they had no idea it was happening at the station. This company thrives on data, they need evidence for everything unfortunately.
Secondly, shouldn't we be making a bigger issue of the change that IS a blatant change of the contract - 2 class config ALT now being Y/J instead of firm J? Quite a few 2 class 380's coming along with less seats upstairs, this can become more of an issue.
