Many thanks for this wonderful info !!

I was devising a strategy to switch to a BA premium plus card (£150 fee, but 6K bonus miles) to accumulate some 22K miles in the next 9-10 month to make use of the companion voucher.

Just wondering whether MR card and my current BA Amex card can point to the same executive club account so that I benefit from companion voucher as well as this extra 20K miles that MR would bring in. This for the journey we are planning to Thaliand next year. Currently I have just over 138K+ so need additional 22K miles to make it in F. Many thanks !!!
