I haven't seen a specific discussion about this here...

I've been with BAEC ever since the demise of BD Diamond Club (RIP) and just stayed with them out of convenience. After lo these many years I decided to look into it and turns out I'd be better off using IB+. For my flying patterns, TPs come out almost exactly the same, but since I'm forced to fly VY several times a year getting tier points for those is a plus. It also seems that the various perks and promos offered by IB are of more use to me than the UK-centric ones from BA.

Has anyone ever tried to get IB status matched from BA? Any luck? Suggestions for best strategy?
