Unfortunately, some of the ingredients that made old L'Air du Temps so wonderful are now not allowed. The current edt is just a shadow of its old self, and I can't imagine the parfum is as nice as it once was. I have not smelled the current extrait...but personally I would not buy any without trying it first. On the other hand, they probably do save the best ingredients for the lalique flacons, so it might very well be lovely. I have bought vintage L'Air du Temps in both parfum and edt, and neither seems to hold up well. Sad to say goodbye to an old love.
p.s. I'm sorry that didn't answer your question! Just commiserating here.
