I've just done a LHR/BOM return in WTP, and had the same gripe both directions: full cabin, and no meal choice when they got to me - i.e. Indian Veg only. Both times was offered chicken from economy, both times declined and suggested they get me something from CW (which they did).

The other common gripe I have in WTP is that, whilst the WTP cabin can be completely full, Y can be half-empty. So whilst the Y occupants get to spread out, and have rows of three to themselves, we're crammed in. At times I'd rather forego the (minimal) experience of WTP, and be offered a downgrade to Y if I could be allocated the entire row of three (or four).

Regarding no sparkling wine on flights in to London, I queried this at JFK, and the purser simply replied "it's BA policy". Go figure.

I'd heard somewhere (on FT?) that BA had retained the old Club blankets and were going to roll those down to WTP - not sure if that's true or not.
