Just back from Europe and like many I've seen hundreds of warning videos and comments about the new EES system when entering or exiting the Europe. We arrived in Vienna in early May and had literally no wait when we went through Passport control. Our point of exit was from the Frankfort airport yesterday and we had a wait of 45 minutes. Nothing overly bad or worth worrying about. I always tend to make longer layovers anyway. Long story short, I think much of the EES problems have been worked out.
