Afraid the answer is simple.
Despite I like T5, I have sacrificed my BA Silver for *A Gold as BA is IMHO not worth the money they charge for overcrowded lounges with awful food. BoB I can't stand as well.
I am sure they still have enough BA Gold's who will fly whatever it takes but it's not my personal cup of tea anymore - so I have exchanged my BA AMEX into the MBNA Platinum Skywards card, etc.
I might come back if the reduce the prices by 30%
