Amadeus GG Command Guide: Access AIS Airline, Hotel & Country Info

A complete guide to the GG command in Amadeus — how to access AIS (Amadeus Information System) pages and retrieve reference information about airlines, hotels, car rental companies, and countries.

Booking a trip is not only about flights, fares, and seats. It also requires knowledge about the airlines involved, the hotels on offer, the car rental companies available at a destination, and the country the customer is travelling to. Amadeus stores all of this information in a reference system known as the Amadeus Information System (AIS), and the GG command is the entry used to access it. From airline policy pages and hotel chain descriptions to car rental access types and country information, GG provides a broad reference toolkit directly inside the terminal. This guide walks through each major GG variation with a working example.

What Does the GG Command Do?

GG is the Amadeus GDS command used to access AIS (Amadeus Information System) pages and retrieve information about airlines, hotels, car rental companies, and countries.

Category: Information System (AIS).

It provides access to different information categories stored in the Amadeus Information System, including airline, hotel, car rental, and country information. It is a companion to the encoding and decoding commands — for example, once a code is identified with DAC or DNA, you can look up the detailed information with GG.

General AIS Access

Access the AIS subjects:

GGAIS

Request an alphabetical list of AIS categories:

GGA

This displays the main AIS categories available. Use it as a starting point when you are not sure which category or code to enter.

Airline Information

Request the airline information AIS page:

GGAIR

Request information for a specific airline:

GGAIRAF

This displays the reference page for the airline matching the code — in this example Air France. Use it to check baggage policies, ticketing arrangements, frequent flyer rules, and other airline reference information that is not covered by the fare rules.

Hotel Information

Request hotel information:

GGHTL

Request a description of hotel access types:

GGHTLALL

Request the alphabetical list of hotel chain codes:

MS23

Request information for a specific hotel chain:

GGHTLSI

This displays the reference page for the hotel chain matching the code — in this example Sheraton. Use it to check chain-wide policies, loyalty programmes, and brand descriptions before booking.

Car Rental Information

Request car rental information:

GGCAR

Request car rental companies’ access types:

GGCARA

Request information for a specific car rental company:

GGCARZE

This displays the reference page for the car rental company matching the code — in this example Europcar. Use it to check company-wide policies, insurance requirements, and access details before adding a car to the booking.

Country Information

Request the country information index:

GGCOU

GGCOUNTRY

Request an alphabetical list of countries with information stored in AIS:

GGCOUD

Request information for a specific country:

GGCOUFR

This displays the reference page for the country matching the code — in this example France. Use it to check entry requirements, currency, time zone, travel documents, and other country-level information relevant to the booking.

When to Use GG

Use GG when you need to access Amadeus reference and informational pages for airlines, hotels, car rentals, or countries through the AIS system. Typical scenarios include:

Checking airline baggage policies, ticketing arrangements, or frequent flyer rules.
Confirming hotel chain policies, loyalty programmes, or brand descriptions before booking.
Reviewing car rental company access types and insurance requirements.
Checking country entry requirements, currency, or time zone information.
Finding the correct code for an airline, hotel, car rental, or country through the AIS index.
Supporting customer queries about airlines, hotels, or destinations mid-booking.
Verifying reference information that is not covered by the fare rules or the PNR.

How GG Fits Into Your PNR Management Workflow

A typical session using GG might look like this:

Retrieve the PNR with RT or begin a new booking.
Identify the reference information needed — airline policy, hotel chain details, car rental access, or country information.
Enter the appropriate GG entry — for example GGAIRAF, GGHTLSI, GGCARZE, or GGCOUFR.
Review the information returned and use it to answer the customer or guide the next booking step.
Use DAC or DNA if you need to identify a code before requesting a GG page.
Continue with the booking — for example with AN for availability or FXP for pricing.
Save the PNR with ER or ET.

How GG Relates to Other Reference and Encoding Commands

GG → accesses AIS information pages for airlines, hotels, car rentals, and countries.
DNA → encodes and decodes airline names, codes, ticket codes, and alliances.
DNH → encodes and decodes hotel company codes.
DNC → encodes and decodes car rental company codes.
DAC → decodes city or airport codes.
DAN → encodes city or airport names into codes.
DNS → encodes and decodes state and province names and codes.
TI → requests travel information such as visa, health, country, rules, and news.

The distinction matters: encoding and decoding commands (DAC, DAN, DNA, DNH, DNC, DNS) identify codes; GG provides detailed reference pages for those codes; TI provides travel information such as visa, health, and rules. Use them together for complete reference coverage.

Important: GG returns reference information only — it does not confirm availability, prices, or schedules. AIS pages describe airline policies, hotel chains, car rental access types, and country data, but the actual booking still requires the standard commands such as AN for availability, DO for flight details, and FXP for pricing.

AIS information is maintained by the airline and by Amadeus, but it can change without notice — particularly airline policies, hotel loyalty programmes, and country entry requirements. For the most current data on a specific booking, always confirm with the supplier directly.

Frequently Asked Questions

What does the GG command do in Amadeus?

GG accesses AIS (Amadeus Information System) pages for airlines, hotels, car rental companies, and countries.

What does GGAIRAF mean?

It requests the AIS information page for the airline matching the code AF — in this example Air France.

What does GGHTLSI mean?

It requests the AIS information page for the hotel chain matching the code SI — in this example Sheraton.

What does GGCARZE mean?

It requests the AIS information page for the car rental company matching the code ZE — in this example Europcar.

What does GGCOUFR mean?

It requests the AIS information page for the country matching the code FR — in this example France.

How do I find which AIS pages are available?

Use GGA for an alphabetical list of AIS categories, or GGAIS to access the main AIS subjects.

Conclusion

The GG command is the Amadeus Information System (AIS) access tool. Use GGA and GGAIS to explore the AIS index, GGAIR and GGAIRAF for airline reference pages, GGHTL and GGHTLSI for hotel chain details, GGCAR and GGCARZE for car rental access and policies, and GGCOU, GGCOUD, and GGCOUFR for country information. Together they give you a broad reference toolkit inside the terminal, supporting customer queries and booking decisions without needing external information sources. Remember that GG only provides reference data — for availability use AN, for flight details use DO, for pricing use FXP, and for travel rules and country details use TI. Paired with the encoding and decoding commands — DAC, DAN, DNA, DNH, DNC, DNE, and DNS — GG completes your reference data toolkit and keeps every booking informed, accurate, and compliant.
