Just check you didn't get some other miles, like LH miles.
It was a round trip with my MP account number logged into the booking. I still have the BP's (conveniently bookmarking some Jeremy Clarkson paperback i'm reading at the mo), both display the LH ticket number and noted UAP in the tear off portion.
