I'm trying to keep track of the UK sales here
current BA sales ex-UK thread on FT
It's only for ex-UK sales....
I would certainly expect to see a Club World/CE sale for July/August sometime after Easter - this has been a regular fixture the last few years and is principally due to UK summer holidays having a major impact on people travelling for business. The Christmas/New Year CW/CE sale has also been a regular fixture, usually starting sometime in late Autumn.
I think we may see another WT/WT+ sale quite soon, perhaps kicking off during the Easter break - pure conjecture on my part though...
