TBH I'm surprised that no-one has done this before now.
Loathe as I am to defend BA it has been quoted that to give pax time to get used to the changes, the 32kg weight limit will remain in place until 30th Septmeber.
It very much depends where you are flying to as well, for instance if you were going to Australia the weight allowance is lower (i.e 23kg) than if you were going to the USA (which is still 32kg).
