Sorry if this has been discussed but a search failed to find the answer, and the CO and LH web sites are equally cryptic on the point (or I'm just slow). Which LH lounge or lounges are available to CO BF customers in FRA? (I'm a newbie post-Sky Team to connecting in FRA to a CO flight; used to connect in AMS or CDG). I see that LH has "Business" lounges and "Senator" lounges, and I've read that the latter may be somewhat better, but it's a bit unclear in general let alone with respect to BF passengers on CO. My specific itinerary has me on business from FLR to FRA on LH, then CO 47 FRA-IAH in BF. I'm also Star Gold if that makes any difference as to lounge access. Thanks!
