Well thanks, but part of what I meant to convey was that we at AC would also have no way of serving red wine or any half-fun drink other than bubbly while on the ground at LHR without running afoul of HM Customs regulations. Pretty much the same deal as on BA.

I think I read upthread that BA also have top-ups of soft drinks loaded other than in duty-exempt stowages in some of their galleys.
