I'm booked in z (July travel) for grr-ord-muc-krk and then return vce-fra-ord-grr.

Some flights are united (grr-ord-muc) then lufthansa (muc-krk). Returning, its LH from VCE-FRA-ORD and then UA from ORD-GRR.

When I looked at my itinerary on united.com, I noticed it listed award miles for all the united served legs, but is showing 0 miles earned for anything that is Lufthansa metal.

Is this simply a lack of integration on the part of the ff programs? I assume that everything will work itself out during and after the trip. The entire reservation has my BMI diamond club ff# to receive the miles. If at the end of the day, should I be letting BMI know of missing miles and provide them with the board passes if needed?

Thanks much!
Dennis
