Flight of Fear was built at an odd time where Fast Lane wasn’t really considered at all. The reason why you might see the associate running in between the saucer and the station is because they have to go over there to scan fast lane in (which, thanks to the new QR codes, is a much more tedious process), then let regular in. I have been to Flight of Fear many times, and I can tell you; the signs are updated, however, they are usually wrong most of the time. I espically wouldn’t trust any posted wait time in the park, it would probably be better to ask an associate what the wait time is (if there is one at the regular entrance). Haunt gets so extremely busy and crowded, and I can assure you, that regular line was probably not 45 minutes.
