Flying ORD to FCO in the next 10 days. Wife and I will be in First Class while my children (14 and 17 year old) will be in Business Class. Will be in LHR for 3-4 hours before catching connecting flight to FCO.

Question - Will the gatekeepers allow my children into the Concorde lounge with their biz class tickets and to keep the family together? Or will my wife and I be "downgraded" to Galleries/Terraces lounge?

Thanks in advance!
