Abstract
A method and apparatus for controlling passenger flow into and out of an aircraft. The apparatus can include a walkway elongated along a longitudinal axis and having a first portion and a second portion with the first portion configured to be positioned adjacent to an aircraft doorway. The walkway can have a width generally transverse to the longitudinal axis sized to accommodate at least two people walking abreast. A restriction can be coupled to the walkway and can extend along the longitudinal axis to divide the walkway into a first aisle and a second aisle with each aisle being elongated along the longitudinal axis and with the restriction at least restricting movement by people from the first aisle to the second aisle. The restriction can be moveable relative to the walkway between a stowed position and a deployed position and can include elements such as upright members, transverse handrails, and/or flexible planar sheets.
