I will be slightly OT as this is a KLM thread, but will provide AF information. On the AF side, it has always been hit & miss. During S1-2017, the situation was deteriorating constantly with the priority bags always delivered the last. I reported the problem several times and I have noticed a dramatic improvement either in CDG and in outstations and also for the delivery time since last summer. My bags are now consistently among the 1st on the belt.
