Excellent initiative and should indeed be a masterthread. ^ Could I possible suggest creating one post for each lounge [which could progressively be given info such as entry conditions - e.g. some of them are only for J/P and not for ST E+/FB G/P etc, whether there are wifi, showers, any special "tips" (as in NCE where there is Champagne but it needs to be requested), etc]. The first post could keep the list of all lounges and have links to the individual lounge posts?

A few notes:

NCE: of the four airport lounges, AF actually uses two - Cap Ferrat (as you mention) for Schengen flights, but also Cap d'Antibes after passport control for non-Schengen flights (TLV, TUN if it is reinstated, AF codeshares to JFK, SVO, etc).

BOD: similarly, the Patio lounge is only for Paris flights, there is another airport lounge for all non-Paris flights. (note: AF keeps changing between allowing pax in or giving them a voucher for non-Paris flights so not sure what the current system is)

CDG: is there still a TGV lounge access for Strasbourg trains?

Belgium: there is also a BRU lounge (A5 still has flights to LYS, and NTE-BOD I believe) although I'm not sure if they still subscribe to the lounge or not.

DUB: lounge is no longer called Ana Livia (hasn't for a couple of years) but "DAA Airport Lounge"

LAX: I don't think there is a QF lounge but just the OW lounge (although it is fortunately QF in every possible way but name!). Would be good to know if it is to the standard OW lounge or the new OW F lounge?

TLV: I believe the lounge is the Dan lounge (not sure if there is a JetSet lounge, I have never seen it)

PVG: Can't AF pax use the MU lounges too? - I may well be wrong on that!

Also a small pedantic remark - should the list include only airports for which AF flies with its own metal (in which case I don't know why HEL or ZYR are included?) or also flights where AF coded flights only operate as codeshares (in which case many are of course missing)?

Hope it helps!
