Now that T1 has closed again and BA is back at T2, I assume that lounge access is available again for silver and gold BAEC members? I know that the Schengen lounge at T2 is open as I have used it a number of times flying AF or KL but I am not sure what the situation is for BA flights in non-Schengen (Nice airport's website does suggest that both the Schengen and non-Schengen lounges are open).
