Those of us who still have the bmi plus Diamond Club credit cards can clickthrough after logging in to diamondclub.org to receive a 10% discount on a BA flight.

When I use this link to try and book shorthaul fares the hand baggage only option is not available to book.

Has anyone booked a HBO fare with this offer or are they not combinable?

My feeling is it's a bug because the HBO fares were introduced after the bmi discount.

I'm not sure who to contact about this to get a definitive answer. I'm sure most at the BA callcentre won't be aware of this discount and of course MBNA won't know much about BA IT and whether we're supposed to get a discount on HBO fares.

I also sometimes have the issue that business class fares are not discounted (but first are) but this discount is supposed to apply to all classes.
