Slightly OT - one thing I always relish getting onto a BA flight after an extended period abroad is that first, good, strong British cup of tea. Very few countries (and no airline I have yet found) can match a proper British cup!
Your thread also reminds me of GF around 6 months to a year back who offered a range of "Tea Forte" teas (fruit and otherwise) which I absolutely loved. They seem to have vanshed now - anyone know what happened, or were these "enhanced" too? The Twinings just aren't on the same level!
I must admit I do love the range of Fortnum & Mason loose leaf teas available in T5 - while not necessarily cheap, they go a long way and are well worth the extra.
