It works on the website, but you have to remember before searching for the fare, to click on "1 passenger" in the search form, click on yourself, and then only it will load the different discount cards you have....

It would be great if AF automatically searches for fares with all possible discount cards (or not), so in my case for no discount + weekend card + abonné card, and then I could choose what fare suits me best... Oh well, that's dreaming
To compare, here is what I have without the weekend card:
And with the weekend-card:
Here it's 10€ less for the week-end card (and the abonné fare was 277€).
