to give my small contribution
Got back yesterday from AMM with 3 AF tickets: i was the FB Gold
Lounge is the Royal Crown used by all others companies
Wife could get in as my guest and they gave the courtesy for my 12y daughter. No discussion required. Airfrance staff could not guarantee my daughter would came in, but the lounge attendant was very kind
The lounge is very wide, so it s not an issue for them i imagine
