In Queue vs. On Queue
For the ordinary sense of waiting in a line or list, English uses “in the queue” or “in a queue”; Cambridge gives examples such as “Are you in the queue for tickets?” “On queue” is not the ordinary equivalent of that waiting construction and should not replace it without a specialized system-specific reason.
Use “in the queue” or “in a queue” for someone or something waiting to be handled. Do not substitute “on queue” as the ordinary waiting expression.

Article Note
In ordinary prose, “in the queue” or “in a queue” is usually more natural than bare “in queue,” though technical interfaces may use compressed labels.
Ordinary Waiting Use
Use “in the queue” when a person, request, file, or task is waiting in a queue.
Specialized Boundary
A software or operational system can define its own label containing “on queue”; do not generalize such labels into the ordinary English waiting construction.
