Queues area offers you a list with all the Queues containing PNRs. To access Queues, open the Terminal Menu, go to the Queues tab and tap on the Queue you wish to check. The terminal will show you a list with all its PNRs, so you don’t need to travel through the PNRs to reach the one you are looking for.
To access a specific PNR just touch the PNR code which is a linked command.
To remove a PNR from the Queue you can do QR/[Queue Number] e.g. QR/99.
