Amadeus HU Command: Hotel Auxiliary Segment

A complete guide to the HU command in Amadeus — how to create a hotel auxiliary segment in a PNR, recording hotel location, dates, room type, and booking details.

A customer’s journey rarely begins and ends at the airport. Accommodation is often an integral part of the trip, and the travel agent needs to record it in the PNR alongside the flights. The HU command is the Amadeus entry that handles this. It allows you to add a hotel reservation to the PNR as an auxiliary segment, including the hotel location, the check-in and check-out dates, the room type, and any other booking details. This guide explains what HU does, the correct syntax, and when it should be used.

What Does the HU Command Do?

HU is the Amadeus GDS command used to create a hotel auxiliary segment in a PNR.

Category: Auxiliary Segments.

It is used to add a hotel reservation to the PNR, including the hotel location, dates, room type, and other booking details.

The HU segment appears in the itinerary alongside the flight segments, giving a complete picture of the trip. It records the accommodation information for the traveller, the agent, and any other colleague who may work on the booking later. Combined with RU for memo services and other auxiliary segments, HU keeps the PNR as the single source of truth for the entire journey.

Syntax & Example

Create a hotel auxiliary segment for one double room in Rio de Janeiro from 1 September to 3 September:

HURGNN1RIO01SEP-03SEP /1 DOUBLE COPACABANA HTL

This creates a hotel auxiliary segment recording the following details:

City — Rio de Janeiro (RIO)
Check-in — 1 September
Check-out — 3 September
Room type — 1 double room
Hotel name — Copacabana HTL

The segment appears in the PNR itinerary as a hotel element, immediately visible whenever the booking is retrieved or displayed.

When to Use HU

Use HU when adding a hotel accommodation service to a PNR as an auxiliary segment. Typical scenarios include:

Adding accommodation to a leisure booking alongside flight segments.
Recording a hotel arranged for a business trip.
Documenting a room for a group booking where accommodation is part of the package.
Adding an extended stay or stopover accommodation to an international itinerary.
Recording a pre- or post-cruise hotel night as part of a package.
Noting the hotel for a special event or conference booking.
Adding accommodation arranged outside the standard hotel availability flow so the booking reflects the full trip.

How HU Fits Into Your PNR Management Workflow

A typical session using HU might look like this:

Retrieve the PNR with RT and confirm the flight itinerary is complete.
Confirm the accommodation details with the customer — city, dates, room type, hotel name.
Enter the HU entry with the correct city code, dates, room configuration, and hotel name.
Verify the hotel segment appears correctly by redisplaying the itinerary with RTIM.
Add any supporting remark with RM if extra detail is required — such as the room rate, reservation reference, or cancellation policy.
Save the change with ER or ET.

How HU Relates to Other Auxiliary and PNR Element Commands

HU → creates a hotel auxiliary segment in the PNR.
RU → creates a memo auxiliary segment for informational travel 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 to the PNR.
OP → creates an option element for follow-up actions.
AM and AB → add mailing and billing address elements to the PNR.
RH → displays the PNR history, including auxiliary segments.

The distinction: HU records accommodation as a hotel auxiliary segment; RU records other informational services; RM, RX, and RC add remarks that do not appear as itinerary items. Use HU when the accommodation should be visible as part of the trip.

Important: The HU entry records the hotel information in the PNR. Whether it creates a bookable reservation depends on the format used and the supplier. In many cases, HU is used as an auxiliary segment to reflect a hotel booking arranged outside the standard availability flow.

Always confirm the correct city code, dates, room configuration, and hotel name before entering the segment. A wrong date or city will be visible in the itinerary and could mislead the passenger or the next agent working on the booking.
