I can't seem to find anything that may talk about the merging of BA Avios and BMI diamond club accounts...thought maybe I missed out on an email. Any clues?
You need to wait until 3rd July. Another thought today, if you have some BAA Worldpoints lying around (or plan to accumulate more before BAA offload EDI airport) then 500 Worldpoints = 750 DC Miles, but only 500 Avios, so pump them into Diamond Club while you have the chance and reap more Avios later
Actually, 500 WP = 600 Avios. The rate was upped quite a while ago, and the redemption size is only 250 (for 300). That said, if you have nothing better to do with them, the idea is sound.
