I was just looking into booking flights at the LH website that involves a segment on United with an LH codeshare flight number. The LH website tells me that there will be no mileage credit to M&M for that segment. Is this true? However, if I book the same segment as a United flight, with UA flight number, I can have the miles credited to LH M&M. Doesn't make sense to me. Or is the info on the LH website wrong?
