Amadeus TTI Command: Manually Update TST Info

A complete guide to the TTI command in Amadeus — how to manually update TST validity dates, baggage allowance, fare basis, fare calculation, net fare, and fare elements before ticket issuance.

TTI is the Amadeus GDS command used to manually update TST information such as validity dates, baggage allowance, fare basis, fare calculation, and fare elements.

Category: TST / Ticketing.

The TTI command allows you to manually modify different elements of a TST, including segment details, baggage allowance, fare basis, fare calculation, and fare amounts. Each variation targets a specific part of the ticket record and can be applied to all segments or to specific segment numbers. For fare, tax and total updates, use the companion TTK command.

💡 Pro-Tip — Always Redisplay the TST After a Manual Update

TTI changes the TST silently — the entry is accepted, the PNR is saved, and no visible error appears. But the record you edited is not the record you have been reading on screen. Before issuing the ticket, you must redisplay the TST to confirm the change landed correctly.

1️⃣ TTI/...    → apply the manual update
2️⃣ TQT        → redisplay the TST (formatted view)
3️⃣ TQTC       → redisplay in cryptic mode if needed
4️⃣ check each field → validity, baggage, fare basis, fare calc
5️⃣ TTF        → clear the change flag
6️⃣ TTP        → issue the ticket

Rule of thumb: Never issue a ticket straight after a TTI entry. Redisplay with TQT first, verify the field you changed, then proceed. For fare, tax and total updates, use the companion TTK command.

Use TTI when you need to manually update or correct specific TST information, such as validity dates, baggage allowance, fare basis, fare calculation, net fare, or fare elements. Typical scenarios include:

• Applying segment-specific validity dates approved by the airline.
• Setting a baggage allowance that differs by segment.
• Entering a manual fare basis for a child or infant passenger.
• Building a fare calculation line for a manually priced ticket.
• Creating a net fare amount for corporate or airline reporting.
• Adding or removing fare elements for special fare structures.

A typical manual update session using TTI might look like this:

• Retrieve the PNR and create the TST with TTC if needed.
• Apply the manual update using the appropriate TTI variation.
• Redisplay the TST with TQT and verify the change.
• Use TTF to clear the change flag.
• Issue the ticket with TTP.

What does TTI/A30K do?

It sets a 30 kg baggage allowance on all segments in the TST.

How do I delete all baggage allowance information?

Use TTI/A. To delete it for specific segments only, add the segment numbers, for example TTI/L2,4/A.

What is the difference between TTI and TTK?

Both update TST information. TTK focuses on fare, tax, total, and fare calculation elements; TTI focuses on validity dates, baggage, fare basis, fare calculation, net fare, and the full fare element.

Why should I redisplay the TST after a TTI update?

TTI entries change the TST silently — the record you edited is not the same as what was on screen. Redisplay with TQT to confirm the change landed correctly, use TTF to clear the change flag, then issue.
