Claim 15:
16. A queue system for a lavatory of an aircraft, comprising:
a queue module configured to receive a request from a user input device and to create and/or modify a virtual lavatory queue based on a request hierarchy of the request to position the request in the virtual lavatory queue; and
a sensor operatively connected to the queue module and configured to output a state change signal indicative of a user leaving the lavatory, wherein the queue module is configured to:
receive the state change signal;
iterate the virtual lavatory queue in response to the state change signal; and
output a vacancy indicator signal to an indicator device associated with a request that is at a front of the virtual lavatory queue after iterating the virtual lavatory queue to indicate to a next user that it is the next user's turn in the queue; and
a verification module operatively connected to the queue module and configured to verify a user attempting to use the lavatory is associated with the request that is at the front of the queue, wherein the verification module is configured to receive and compare identification data from the user to stored identification data associated with the request that is at the front of the queue, wherein the identification data includes a barcode associated with the request.
