BA have to find a balance between what is a competitive product for all its markets, and enough seats to make sufficient dough.
The current product is now being over taken by many carriers, and even the American carriers now.
Like Senator I think the LX, SN, DL product etc is a good one and provides something for everyone.
The VS product I am not a fan of – I do like to look out the window on day flights. Re the upcoming A80 and 787 products, I would be less inclined to choose any Business Class product where there is a risk of a middle seat. The JL produce looks awesome!
