Amadeus RH Command: Display PNR History

A complete guide to the RH command in Amadeus — how to display the history of a retrieved PNR, including segment changes, queue activity, and record locator history.

RH is the Amadeus GDS command used to display the history of a retrieved PNR.

Category: PNR History.

It allows you to view changes and previous actions made to a PNR, including specific itinerary segments and queue activity.

The history records agent sign, date, and time for each action, making RH an essential tool for auditing, training, resolving disputes, and understanding how a booking reached its current state.

To display the complete history of the retrieved PNR:

RH

This displays the history of the retrieved PNR, showing each recorded action from the moment the booking was created.

To display a specific section of the PNR history:

RHA

This displays a specific section of the PNR history, narrowing the view to the part of the record you need.

To review the history of one itinerary segment:

RHS4

This displays the history for itinerary segment 4, showing every action recorded against that specific flight — status changes, schedule updates, rebooking, and cancellations.

To display the queue history of the retrieved PNR:

RHQ

This shows every queue placement, category, and removal associated with the PNR — useful for tracking which departments handled the booking and when.

To merge the queue history with the PNR history:

RH/ALL

This combines both histories into a single chronological view, making it easier to see how queue activity and booking changes relate to one another.

To jump to a specific step in the PNR history:

RH049

This displays the PNR history for step 049. Use this when the history is long and you know which step number you need to review.

To display the record locator history:

RLH

This shows the history of record locator changes associated with the PNR, which is useful when a booking has been split, merged, or re-linked and you need to trace how the current record was created.

Use RH when you need to review changes made to a PNR, investigate previous actions, check segment history, or review queue activity. Typical scenarios include:

• Investigating a discrepancy between the PNR and the ticket.
• Confirming which agent made a specific change and when.
• Tracking a schedule change or rebooking on a particular segment.
• Reviewing queue activity to see which departments handled the booking.
• Auditing a booking for corporate or compliance reporting.
• Resolving customer disputes about what was changed and when.
• Tracing record locator changes after a PNR was split or merged.

A typical investigation using RH might look like this:

• Retrieve the PNR and identify the area that needs investigation.
• Enter RH to view the complete history.
• Use RHS4 to focus on a specific segment, or RHQ for queue activity.
• Use RH/ALL to see queue and booking history merged in one view.
• Use RH049 to jump directly to a specific step if known.
• Use RLH to trace record locator changes if the booking was split or merged.
