A queue system for a lavatory (99) of an aircraft (200) can include a queue module (101) configured to receive a request from a user input device (103) and to create and/or modify a virtual lavatory queue (300) based on a request hierarchy of the request to position the request in the virtual lavatory queue, and a sensor (105) operatively connected to the queue module and configured to output a state change signal (301) indicative of a user leaving the lavatory. The queue module can be 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 (303) to an indicator device (107) associated with a request that is at a front of the virtual lavatory queue after iterating the virtual lavatory queue to indicate to a user that it is the user's turn in the queue.
