Well I had priority ticket, and it had two lines seperated for that, but people with casual ticket came before me, and it didn’t feel like having priority pass. Also after going in the gate, people got together, the people who didn’t have priority pass came over to our space, and eventually, the faster line was the casual ticket line.
