Hi-

I have read the AA's website on the admission policy for Admirals Club but still have a question.

I'm flying BOS-LHR day flight this week, and I'm planning to hang out at the BOS AC after checking in.

It turns out that my SIL (no status, no AC membership) will be flying AA the same morning BOS-DFW, but her flight departs 1 hour after mine.

I'll be at BOS AC before she arrives. When she arrives, can I have her meet me at the AC entrance and then guest her in? Or does she have to enter the AC at the same time I enter? Will the agents check her BP and refuse to let her in b/c she's not flying on the same itin as me?
