I didn't get get the information about AC E status from the original post, it was in the program information that appears next to the user name. It appears to me that this has been updated since my post (but I readily admit that I could have mixed it up with a post I read in another thread).

If the OP has no status and is flying UA on the return, there will be no lounge access at a RCC (IIRC they will not be able to access the LAZ T2 lounges without a BP for a flight leaving from T2).
