Amadeus RU Command: Memo Auxiliary Segment

A complete guide to the RU command in Amadeus — how to create a memo auxiliary segment in a PNR to record informational travel services without making an actual booking.

Not every service a customer purchases through a travel agency is a flight, a hotel, or a car. Some are theatre tickets, museum passes, restaurant reservations, ferry crossings, tour activities, or event entries — services that exist outside the standard GDS booking flow but still need to appear in the PNR. The RU command is the Amadeus entry that handles this. It allows you to add memo or informational details to a PNR as an auxiliary segment, so the booking reflects the full scope of what the customer has purchased. This guide explains what RU does, its syntax, and when it should be used.

What Does the RU Command Do?

RU is the Amadeus GDS command used to create a memo auxiliary segment in a PNR.

Category: Auxiliary Segments.

It allows you to add memo or informational details to a PNR, such as tickets, tours, or other travel services.

The segment appears in the itinerary as a memo item — it does not create a bookable air, hotel, or car reservation and it does not send a booking request to a supplier. It is purely informational, providing a record that a service has been arranged or that a customer has purchased something outside the standard travel booking flow.

Syntax & Example

Create a memo auxiliary segment for Louvre tickets in Paris on 15 September:

RU1AHKPAR15SEP/LOUVRE TKTS

This creates a memo auxiliary segment recording the Louvre ticket purchase in Paris (PAR) on 15 September. The entry combines a status code, an airline code reference, the city, the date, and the free-flow text that describes the service.

The segment appears in the PNR itinerary alongside the flight segments, so anyone reviewing the booking can see that a museum ticket has also been arranged.

When to Use RU

Use RU when you need to add a memo or informational service segment to a PNR without creating an actual air, hotel, or car booking. Typical scenarios include:

Recording theatre, concert, or sports event tickets arranged for the customer.
Adding museum, exhibition, or attraction entry passes to the booking.
Documenting restaurant reservations or dining experiences.
Recording tour activities, excursions, or guided visits.
Noting ferry crossings, train tickets, or other transport not booked through a standard GDS supplier.
Adding travel insurance or visa service details as informational items.
Recording any other travel service purchased or arranged outside the standard booking flow.

How RU Fits Into Your PNR Management Workflow

A typical session using RU might look like this:

Retrieve the PNR with RT and confirm the itinerary is complete.
Confirm with the customer or the supplier the details of the memo service to be recorded — city, date, and description.
Enter the RU entry with the status code, city, date, and free-flow text.
Verify the memo segment appears correctly in the itinerary by redisplaying the PNR with RTIM.
Add any supporting remark with RM if further detail is required.
Save the change with ER or ET.

How RU Relates to Other PNR Element Commands

RU → creates a memo auxiliary segment for informational services.
RM → adds a general remark to the PNR.
RX → adds a corporate or business-related remark to the PNR.
RC → adds a confidential remark that is not displayed to the passenger.
SR → creates special service requests linked to a flight segment.
OP → creates an option element for follow-up actions.
RH → displays the PNR history, including auxiliary segments.

The distinction: RU creates an auxiliary segment that appears in the itinerary; RM, RX, and RC add remarks that appear in the PNR but not as itinerary items. Use RU when the service should be visible as part of the trip.

Important: The RU segment is informational only. It does not create a bookable reservation, does not send a request to a supplier, and does not generate a ticket. If the service needs to be booked, purchased, or confirmed with a supplier, that must be handled through the appropriate channel outside the RU entry.

Because the RU segment appears in the itinerary, always confirm the description with the customer and the supplier before entering it. A wrong date, city, or description could mislead the passenger or the next agent working on the booking.

Conclusion

The RU command is the memo auxiliary segment tool in Amadeus. Use RU1AHKPAR15SEP/LOUVRE TKTS to record informational services — theatre tickets, museum passes, tours, excursions, or other travel arrangements — so that the booking reflects the full scope of what the customer has purchased. The segment is purely informational: it appears in the itinerary but does not create a bookable reservation with any supplier. Always confirm the details with the customer before entering the RU entry, and remember that the free-flow text is what describes the service to anyone reviewing the booking. Paired with RT for retrieval, RTIM for itinerary display, RM and RC for remarks, XE to delete an incorrect segment, and RH for reviewing the history, the RU command completes your PNR element toolkit and keeps every booking’s full service list properly documented.
