John - there's not much to say really, other than use it to book BMI flights as you avoid the credit card fee and get the bonus miles.
JP - try
here, although that only seems to be for the classic card even though it does show both card types in the picture [:?]
Edit to add -
this site shows both card types at not having an annual fee. I always thought the silver coloured platinum BMI card did have a fee but that might also explain why I've never paid an annual fee for my platinum BMI M/Card [:?]
Didn't realise you now had to spend £250 in the first 90 days to get the 20K miles. You didn't have to when I got mine [:w]
