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.

Quick tests
Meaning / construction test
Are you describing a person or item waiting its turn in an ordinary queue?
If yes: Use “in a/the queue.”
If no: If this is a technical system state, follow that system’s terminology instead of generalizing “on queue.”
Caveat: The guide addresses ordinary English waiting expressions; specialized products may define their own labels or commands.
Examples
We waited in the queue for tickets.
“In the queue” is the ordinary waiting expression.
Your request is now in the processing queue.
“In” locates the item within the queue.
She was third in the queue.
The person occupies a position within the waiting line.
Further guidance
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.
