I was also going to say I've seen countless people turned away at LAX, IAD, and ORD (a lot at ORD). Being fair, it's not "countless" but I'd say I've seen this a good 50 times while entering the lounge. And I credit my domestic flights (almost all upgraded) to UA while showing my LH *G card for RCC access. The agents clearly will not take my boarding pass alone for entry and the new entry RCC system has made it very cumbersome for them to admit me on the LH *G card while the flight is credited to UA, although they always do. It has taken a few agents 5 full minutes to figure out how to get the system to let me in and sometimes I'm even asked to leave my card and boarding pass and sit down so they can figure it out when it's slower. The problem seems to be that even entering the LH number into the RCC entry system, the system pulls my UA 1K number to overwrite it and rejects entry with 1K and domestic F. They always let me in on the LH *G card, though.
