A method for passenger flow is described. A boarding pass identifier of a boarding pass is electronically identified at a workstation of one or more first workstations at a first level. Boarding pass information associated with the identified boarding pass identifier is electronically retrieved at the workstation. It is determined, via one or more computers, whether the boarding pass is valid based on the retrieved boarding pass information. If the boarding pass is determined valid, a holder of the boarding pass is directed, via one or more computers, to a queue for one workstation of a plurality of second workstations at a second level based on the retrieved boarding pass information. Each workstation of the second workstations has a different queue arranged before the workstation. If the boarding pass is determined not valid, the boarding pass holder is directed away from entering the queues. A system is also described.
