Yes, LP Rosé is the only thing they have right now.

Arrived on LAX-JFK F which was not a problem. I told them I have a flight tomorrow morning to MIA and asked them about GGL access. The agents seemed to be AA only, and she showed me a screenshot on her phone from Dec. 11th that said BA GGL only on international flights. She said I should just show my arriving boarding pass from tonight. I then showed her the BA website which clearly states that GGL (plus one guest) have access on any flight. She said "but the system will not let you in, that's wrong, that's not how it's programmed".

She went on to say that "BA Premier, which is the equivalent of Concierge Key, has access on any flight". I said that I believed GGL is the equivalent of Concierge Key. She and her colleague said "no no, only BA Premier".

So BA has still not sorted this out.
