These changes are in effect now. Presumably the cuts will not be brought back in the near future. Despite the cuts it is still a great flight, and well worth doing. Just don't expect the same luxury as in BA F. My flight was almost full (95 passengers) and the person next to me was flying on a Club fare that he had upgraded to Concorde in one direction (club return from New York) for a couple of hundred pounds ... that is how they are filling the Concorde these days.
I forgot to mention that the sterling silver luggage tags are gone too -- now it is aluminum. Actually very nice, in fact the identical design to the silver tag, just a bit less shiny.
