The death of BMI’s Diamond Club has been slow. First the Lufthansa group of airlines awards were discontinued, then other Star Alliance carrier ones, Virgin Atlantic was next, and now it is time for the partnership with Qatar Airways to end as well.
This is not a surprise as the BMI is being integrated to British Airways slowly. The end of BMI’s Diamond is soon.
This is not unexpected development but it is worrisome that BMI hasn’t made any announcement about this change. You can find the release about this on Qatar’s website. I would expect the same to apply for BMI as well.
