We recently were at the LHR T2 Plaza Premium lounge. I can say that I believe leaving Priority Pass sure cut down on the crowding. Contrast that with the LH T-2 lounge which was nearly completely full for the morning bank of UA and *A flights to the US as and elsewhere. You are allowed one guest on the Amex plat and two children. Its certainly a viable option if you have access until whenever the UC reopens in T-2B. Had an English breakfast with the beans and sausage, eggs, etc. Good enough for me.

Next time thru LHR we'll probably just head to the Plz Prem lounge only, until the UC gets going again. Fingers crossed UA does this in Q4 like they suggested.
