I tried searching for this and drew a blank. My wife and I are both OneWorld Emerald (AA EXP), so I know we can use the First Wing at LHR regardless of class of service. What about any other passengers on our PNR? Normally when traveling we can go thru first class check-in with everyone, but with the First Wing being private security and straight into the lounge, how does that work in this case? We'll have 7 of us flying BA but not in F class.
