Um, yeah, it's a little off-topic but how do you go about collecting miles with one program and receiving the benefits of the other ? I am LH FTL and UA PremEx, flying to LAS in June. I want to collect LH miles (dreaming of Senator) but since it is a UA flight make sure that PremEx shows on the manifest. I gave my M&M number while booking (that was before I got PremEx), so the accounting shouldn't be a problem...
