How to Void a Ticket in Amadeus: Same-Day Cancellation Guide

📅 Updated: October 2026 ⏱ 7 min read ✈️ GDS HUB Editorial

When working on the Amadeus system, you may sometimes need to cancel a ticket that was issued by mistake — wrong name, wrong date, incorrect fare, or duplicate issuance.

In this case, you can process a Void, which cancels the ticket on the same day of issuance before the sales report is closed. If done within the allowed time, the ticket is removed from sales without going through the refund process.

Good to know: A void cancels a ticket on the same day it was issued, within the airline’s void window, so it never enters the sales report as a sale. A refund returns money on a ticket that has already been reported, and the fare rule decides how much comes back.

Step 1: Display the Daily Report

First, check the issued tickets in your sales report:

This command displays the daily report where you can see:

  • Ticket numbers — the document number column
  • Line numbers — the sequence number column (SEQ NO)
  • Passenger names — the PAX NAME column
  • Record locators — the RLOC column
  • Transaction types — TKTT (ticket), EMDS/EMDA (EMD)

Step 2: Process the Void (TRDC)

There are three ways to void a ticket in Amadeus, depending on the information you have available.

1. Void by Ticket Sequence Number (From the Report)

AMADEUS · TRDC/ TRDC/5033 Example: Void ticket sequence 5033

Replace 5033 with the ticket sequence number shown in the SEQ NO column of the TJQ report.

2. Void by Line Number

AMADEUS · TRDC/L TRDC/L3 Example: Void line 3 from the TJQ report

Replace 3 with the correct line number from the report. This is useful when you can see the line in the report but do not want to type the full ticket sequence.

3. Void by Ticket Number (Last 10 Digits)

AMADEUS · TRDC/TK- TRDC/TK-XXXXXXXXXX Replace XXXXXXXXXX with the last 10 digits of the ticket number

If you have the ticket number, you can use the last 10 digits. Example: TRDC/TK-0574373759483.

System response: When the void is successful, Amadeus replies OK - DOCUMENT(S) CANCELLED. The ticket is removed from the sales report and will not be settled.

Step 3: Check Airline Void Policy (HE ETT)

Before processing a void, always confirm that the airline allows it.

AMADEUS · HE ETT HE ETT XX Example: HE ETT MS (Egyptair)

Replace XX with the airline code. This will display the electronic ticketing information and confirm whether void is permitted for that airline.

Important: Some airlines do not permit voiding at all, and a few require specific conditions to be met before a void can be processed. Always run the HE ETT entry for the relevant airline before attempting a void.

Important Notes

  • Void must be processed on the same day of ticket issuance — before the sales report closes. For IATA BSP agencies, this is typically midnight local time.
  • After report closure, you must process a refund (TRF) instead of void (TRDC).
  • Always check airline rules before proceeding — use HE ETT for the specific airline.
  • Ensure the e-ticket record is voided before cancelling the itinerary to avoid inconsistencies in the PNR.
  • Voids are final — there is no process to “unvoid” a ticket. If you void by mistake, a new ticket must be issued.
ADM warning: Tickets that are voided but still used by the customer, or tickets that are voided and not properly removed from the PNR, can trigger Agency Debit Memos (ADMs). Always cancel the corresponding PNR segments after voiding a ticket. For more details, see What Causes ADM in Airlines.

Understanding the void procedure in the Amadeus system helps travel agents avoid ADM charges, maintain accurate sales reports, and handle ticketing errors efficiently.

Frequently Asked Questions

What is the TRDC command in Amadeus?
TRDC is the Amadeus GDS command used to void (cancel) an issued ticket on the same day of issuance. It can be used with a ticket sequence number (TRDC/5033), a line number from the sales report (TRDC/L3), or the last 10 digits of the ticket number (TRDC/TK-0574373759483). The system replies OK – DOCUMENT(S) CANCELLED when successful.
What is the TJQ command in Amadeus?
TJQ is the Amadeus GDS command used to query the sales report. It displays all documents issued today, including ticket numbers, line numbers, amounts, tax, commission, and passenger names. Agents use TJQ to confirm whether a sale is still in today’s report before attempting a void.
What is the HE ETT command in Amadeus?
HE ETT is the Amadeus help entry that displays airline electronic ticketing information and rules. Use HE ETT followed by the airline code (e.g., HE ETT MS) to confirm whether the airline supports void and to review its specific void policy before processing a cancellation.
When can I void a ticket in Amadeus?
A ticket can only be voided on the same day of issuance before the sales report closes. For IATA BSP agencies, this is typically midnight local time. Once the sales report closes, the void option is no longer available and a refund (TRF) must be processed instead.
What happens if I miss the void window in Amadeus?
If the sales report has closed, you must process a refund instead of a void. Refunds follow the airline’s fare rules and may include cancellation penalties. Voiding is always the cleaner and cheaper option when available because it removes the sale before it enters the settlement period.
Can I void a ticket by ticket number in Amadeus?
Yes. You can void a ticket by ticket number using the format TRDC/TK- followed by the last 10 digits of the ticket number. For example: TRDC/TK-0574373759483. This is useful when you have the ticket number but do not have the sales report open.
What does the OK – DOCUMENT(S) CANCELLED message mean?
OK – DOCUMENT(S) CANCELLED is the Amadeus system response confirming that the void has been processed successfully. The ticket has been removed from the sales report and will not be settled. If you do not receive this message, the void was not successful and you must check the ticket status.
Does voiding a ticket cost money?
No. A void removes the sale before it is reported, so there are no cancellation fees or penalties. The ticket is simply cancelled and never enters the settlement period. This is why agents always prefer void over refund when the ticket is still within the void window.
