Amadeus TTA Command: Add Passengers to TST Guide (2026)

Q: What does TTA/P2 do in Amadeus?

TTA/P2 is the Amadeus TTA command that adds passenger 2 to the only existing TST in the PNR.

Q: How do I add an infant to a TST?

Include the /INF indicator — for example TTA/P3/INF/T2,4 . The Amadeus TTA command requires this indicator whenever the passenger is an infant, to ensure the correct fare category is applied.

Q: Can I add passengers to more than one TST at once?

Yes. List the TST numbers — for example TTA/P3/T2,4 — or use a range such as TTA/P1-3/T1-3 . The Amadeus TTA command supports both comma-separated lists and range entries.

Q: What is the difference between TTA and TTS?

Within Amadeus TST management, the Amadeus TTA command adds passengers to an existing TST, while TTS splits passengers out. They are the two sides of restructuring — TTS breaks TSTs apart, TTA brings them back together.

Q: Does the Amadeus TTA command change the fare?

No. The Amadeus TTA command only associates passengers with a TST — it never changes the fare, the taxes, or the pricing itself. Those changes are handled by TTK , TTC , or a repricing command.

Amadeus TTA Command — Add Passengers to an Existing TST

A complete guide to the Amadeus TTA command — how to add one or more passengers to an existing TST, including infant passengers and multiple TST records.

Key Takeaways

TTA adds one or more passengers to an existing TST — it never changes the fare itself.
Use TTA/P2 for a single passenger on the only TST in the PNR.
Use TTA/P3,5/T2 to add multiple passengers to a specific TST.
Always include /INF when the passenger is an infant.
Range entries like TTA/P1-3/T1-3 handle group restructuring in one command.
TTA adds passengers, TTS splits them out — they are the two sides of TST restructuring.

When a PNR contains several passengers and multiple TSTs, the system needs to know exactly which travellers belong to which ticket record. The Amadeus TTA command is the entry that handles this association. It allows you to add one or more passengers to an existing TST, including infant passengers, and it works whether you are assigning a single traveller to one TST or building several TSTs across a group. TTA is the natural counterpart to the TTS command — where TTS splits passengers out of a TST, TTA brings them back in. For structured learning, you can also explore our Amadeus Basics Exam.

What Does the Amadeus TTA Command Do?

TTA is the Amadeus GDS command used to add one or more passengers to an existing TST.

Category: TST / Ticketing.

The Amadeus TTA command allows you to associate specific passengers with one or more TSTs, including infant passengers. Nothing is priced or issued during this step — TTA simply tells the system which travellers belong on which ticket record.

This makes TTA essential in multi-passenger bookings, family bookings with infants, and group PNRs where TSTs have been split and need to be rebuilt or restructured.

Amadeus TTA Command — Add a Passenger to the Existing TST

The simplest form of the Amadeus TTA command works when the PNR contains a single TST. You just specify the passenger number, and the system assigns that traveller to the only TST available.

Add passenger 2 to the only existing TST:

TTA/P2

This adds passenger 2 to the only existing TST in the PNR. It is the most common form of the command in single-TST bookings.

Amadeus TTA Command — Add Multiple Passengers to a Specific TST

When more than one TST exists and you know exactly which one should carry a set of passengers, the Amadeus TTA command accepts a passenger list separated by commas and a TST reference.

Add passengers 3 and 5 to TST 2:

TTA/P3,5/T2

This adds passengers 3 and 5 to TST 2, associating both travellers with that specific ticket record.

Amadeus TTA Command — Add an Infant to Multiple TSTs

Infant passengers are handled with the /INF indicator. This matters because infants are often associated with an adult’s ticket record rather than their own — using the wrong syntax can leave the infant unassigned or cause the wrong fare category to be applied.

Add infant passenger 3 to TSTs 2 and 4:

TTA/P3/INF/T2,4

This adds infant passenger 3 to TSTs 2 and 4. Always use the /INF indicator when the passenger is an infant; without it, the system may reject the association or apply the wrong fare category.

Amadeus TTA Command — Add Multiple Passengers to Multiple TSTs

The most powerful form of the Amadeus TTA command handles group restructuring in a single entry. Using hyphens, you can specify passenger ranges and TST ranges at the same time — ideal for group bookings where multiple travellers need to be spread across several ticket records.

Add passengers 1 through 3 to TSTs 1 through 3:

TTA/P1-3/T1-3

This adds passengers 1 through 3 to TSTs 1 through 3 in a single entry — useful for group bookings where all passengers need to be assigned across multiple ticket records.

When to Use the Amadeus TTA Command

Use the Amadeus TTA command when you need to associate passengers with an existing TST, especially when a TST must be assigned to specific passengers or multiple TSTs. Typical scenarios include:

Rebuilding a TST after passengers were split out using TTS.
Adding a child or infant to the correct TST after repricing.
Assigning specific passengers to a reissued TST.
Group bookings where passengers need to be distributed across several TSTs.
Correcting a TST that was created without the right passenger associations.

How It Fits Into Your Ticketing Workflow

A typical ticketing session using the Amadeus TTA command might look like this:

Retrieve the PNR and display the TSTs to see the current passenger groupings.
Decide which passengers need to be added to which TST.
Enter TTA/P2, TTA/P3,5/T2, or the appropriate entry.
For infants, always include the /INF indicator.
Redisplay the TSTs to confirm the passenger associations are correct.
Continue with pricing, reissue, or ticketing for each group.

Amadeus TTA Command vs Other TST Commands

The Amadeus TTA command is part of a broader family of TST restructuring commands. Here is how it relates to the others:

Command	What It Does
`TTA`	Adds passengers to an existing TST
`TTS`	Splits passengers out of an existing TST
`TTH`	Displays the TST history to confirm the changes made
`TTK`	Updates the fare or taxes in the TST
`TTC`	Creates a new TST shell manually
`TQT`	Displays the TST contents

The key distinction: The Amadeus TTA command adds passengers; TTS splits them out; TTH shows the history. Together they give you full control over how passengers are grouped across TSTs in a multi-passenger PNR. You can also utilize tools like the GDS Farebase Generator for further operational assistance.

💡 Pro Tip: Always Confirm with TTH After TTA

After running any form of the Amadeus TTA command, display the TST history with TTH. This shows exactly what changed, in what order, and by which entry — so you can catch any mistake before proceeding to ticketing. It is a small step that saves costly corrections later.

For the official Amadeus documentation, refer to the Amadeus Altéa Suite documentation — the authoritative source for all TST commands.

Conclusion

The Amadeus TTA command gives you precise control over which passengers belong to which TST in Amadeus. Whether you are adding a single traveller to the only TST, associating multiple passengers with a specific TST, or attaching an infant to several records, TTA handles the association cleanly and without touching the fare itself.

Use TTA/P2 for a single passenger, TTA/P3,5/T2 for several passengers on one TST, TTA/P3/INF/T2,4 for infants, and range entries such as TTA/P1-3/T1-3 for group restructuring. Always verify the result with TTH before continuing.

Paired with TTS, TTH, TTK, and TTC, the Amadeus TTA command completes the TST restructuring toolkit and ensures every passenger is correctly linked to their ticket record — from the moment you start building a multi-passenger TST to the moment you issue the final ticket.
