Hello. I believe my ticketing scenario is a bit convoluted so the "search" and "faq" sections dont clearly answer Plus I received contradicting answers when I recently visited a Galleries lounge.
*** Please shoot me down quickly and point to another thread if this is a duplicate or I can find the answer (I did a little a searching, I promise)

Leg 1:
June 2024 flight JFK to LHR, layover then onto Athens.
AA Award miles for 6 passengers but BA metal.

Wife and I in Biz class & 4 teenagers in PE (Im cheap and they need to learn suffer a bit)
2 Seperate PNR due to class difference.
I am EXP and have AA lounge membership via citicard

?: by other than attendant grace, will 4 kids be granted lounge access in LHR? I believe I get 1 guest. If no, are there any day pass purchase options with BA?

Leg 2:
Athens to JFK
AA award on AA metal
Daughter and I booked Biz, wife and 3 kids in PE.

?:ATH BA lounge access for wife and 3 kids.

thanks in advance and again, sorry if dup scenario!
