There is no more clear separation between Accès Numéro 1 security check lane and other lanes at T2D (after the SkyPriority door), and Security agents send any passengers to the so-called fast lane.
It happened to me today and two weeks ago, and had to wait 15 minutes to go through security when it was done in just a breeze before.
Which means that fast lane at T2D is a nonsense.
