Thanks Goldorak! I read in someone else's blog that the ticket must be issued by AF: http://onemileatatime.boardingarea.c...lounge-access/. Does that mean that the ticket has to be booked directly through AF's website or AF's phone reservation? What about tickets purchased through a travel agency or a third party site? My "Z" ticket was purchased through Expedia.

Interesting the blogger would state that condition but I did not see it on the link provided in my OP. Or was that condition a thing of the past?
