My flights in/out of DUB in late Sept and early Oct were quite a hump from the main terminal. IIRC it was from D-65, it also meant no jetbridge for whatever reason. Good thing it wasn't inclement weather, but I couldn't imagine them doing this in the winter.
Back on topic, one of the postings I made on another thread was referenced, but things have changed as of November 1. We still do not know the COS or Booking code of the OP ticket. This is now the determining factor for "allowed" access to the lounge on an AA coded flight.
OP=please be more specific with your flight info so we can give you accurate info in return.
