They have a Club World sale ex-US last March/April and I have bought a Club World ticket from JFK to LHR.
I will be traveling to LHR again this August and I am hoping that they will offer a Club World sale ex-US soon.
I noticed that, when I tried making a dummy booking on BA.com, the fuel surcharge on BA is still US$157 per sector (meaning US$314 roundtrip). I think BA should seriously consider reducing the fuel surcharge, as oil prices have dropped considerably in the past 6 months.
