Aha! The penny has dropped. Thank-you.
I'm just re-reading the BA site and that sentence, "the amount of Avios needed to upgrade is based on the Avios price for a flight in the cabin you wish to upgrade from" is awfully confusing.
It sounds like that should really be "the amount of Avios needed to upgrade is based on the Avios price for a flight in the Economy/WT cabin" or at least something like that?
