Are they making an effort on longhaul biz? I just landed this morning from an embarrassing CW trip from MIA to LHR. The "White company" amenity kit (in lieu of the ridicolous blue bag they gave earlier) was the only notable difference, and totally irrelevant to me. The seat is appalling. If you seat aisle you'll basically sleep on the corridor, if you chose window you'll have to jump your neighbour. If you are middle, well, good luck.
The F product is as poor on air. It gets better on the ground at LHR though, the First wing and Concorde Room are quite something.
