Help with where to credit UA/LH etc as I have forgotten
So I will be on a multi segment Biz ticket. It is a UA ticket, but operated by Lufthansa.......So my question is, because I cannot remember, and my searching here is fruitless: We all know that LH flights earn little on TK since 2014 or so, however what of my sole UA segment on a UA ticket operated by LH? I have not had this exact situation in a very long time and generally just credit my LH flights to LH, but that becomes painful to do for one lone segment.
Thoughts and suggestions?
