Online check in is a joke. I hate waiting for a haircut and try to get them done during lunch hour so I did online check-in. It saif 30 min wait when I checked in. I arrived exactly when indicated and when I arrived the board showed I still have 30 minute wait! I waited 15 minute and our was apparent I wasn't getting in another 20 minutes either. Would be late, had to leave. Better off skipping online check in and waiting or just not going if it shows a 30 min wait online.
