This seems to be the direction Premier Checkin is going across the system... EWR's premier checkin has been a "fenced in" pen with someone acting as a gatekeeper but no internal queues for as long as I can remember; CLE (now since the construction barriers have come down) has the same "pen" concept but gatekeeper depends on time of day, RIC, MSP, BOS, LAS... don't do the full on "pen" but don't have traditional queues on the Premier side
