MESSAGE SIZE EXCEEDED

A complete step-by-step guide for travel agents using Amadeus and GDS systems.

Travel agents and reservation system users often encounter a recurring ticket issuance error when trying to issue flight tickets. In many cases, the problem is caused by an incorrect passenger name format or by an EDIFACT message that exceeds the allowed size limit. This error halts the ticketing process, wastes valuable time, and creates frustration for both agents and customers. This guide explains the common causes, provides practical solutions, and shows the exact commands needed to issue tickets successfully while keeping your PNR open.

Common Causes of the Ticket Issuance Error

This error usually occurs for one of the following reasons:

1. A space between the first name and the title in the passenger name field.

Example: PASSENGER/J MRS — there is a space between J and MRS. This format is often rejected because the name field must follow a specific structure.

2. Issuing tickets for all passengers at the same time.

When you issue all tickets together, the EDIFACT message may exceed the size limit, especially for large bookings or multi-airline itineraries.

3. Airline character limits for ticketing messages.

Some airlines impose a maximum message size. If the ticketing message exceeds that limit, the system returns an error and stops issuance.

Solution 1: Correct the Passenger Name Format

The first step is to check and correct the passenger name format. Remove any space between the first name and the title.

Change this:

PASSENGER/J MRS

To this:

PASSENGER/JMRS

or:

PASSENGER/FIRSTNAME TITLE

The correct format depends on the airline’s requirement. For more details, refer to: HE NAME CHANGE. Correcting the name format not only prevents the error but also reduces mismatches with passports and tickets.

Solution 2: Issue Tickets One Passenger at a Time

Instead of issuing all passengers together, issue tickets individually. Enter the first command:

TTP/P1/RT

Then for the second passenger:

TTP/P2/RT

Continue this process for each passenger. The RT command keeps the PNR open, allowing you to issue the remaining tickets without interruption. This method reduces the EDIFACT message size and avoids the error entirely.

Step-by-Step Ticketing Checklist

Open the PNR and review all passenger details.
Remove extra spaces between the first name and the title.
Confirm the name matches the passport exactly.
Issue each ticket using TTP/P1/RT.
Check each system response to confirm successful issuance.
If the error continues, review airline limits or contact support.

Frequently Asked Questions

What causes the ticket issuance error?

It is usually caused by a space between the first name and title, or by an EDIFACT message that exceeds the allowed size limit.

How do I fix it quickly?

Correct the passenger name format, then issue tickets one by one using TTP/P1/RT.

What does TTP/P1/RT mean?

It issues a ticket for the first passenger while keeping the PNR open for the remaining passengers.

Conclusion

By following these steps, you can avoid the ticket issuance error caused by passenger name spacing or EDIFACT size limits. Always verify the passenger name format, and issue tickets one passenger at a time. These practices speed up ticketing, reduce errors, and improve the overall customer experience for every travel agency.
