*G Lounge Access on EW/AC codeshare
I have a connection onto an EW flight LHR-TXL, but I bought it as an AC flight. Is there any way for the boarding pass to be printed with the AC flight number rather than the EW flight number so I can get lounge access with *G, or is this basically impossible? I know I don't have lounge access if I were just straight-up flying Eurowings.
