A complete guide to the TTF command in Amadeus โ how to remove the PNR change flag from one or more TSTs after completing modifications.
Every time a TST is modified in Amadeus โ whether you update the fare, change taxes, adjust the form of payment, or restructure passenger associations โ the system marks the ticket record with a PNR change flag. This flag is a signal that the TST no longer matches the original PNR data and may need further attention. Once the required modifications are complete and verified, the flag should be cleared so the record returns to a clean state. The TTF command is the entry that removes this change indicator. This guide explains what TTF does, shows the syntax for single, multiple, and range removals, and explains when to use it.

What Does the TTF Command Do?
TTF is the Amadeus GDS command used to remove the PNR change flag from one or more TSTs.
Category: TST / Ticketing.
The TTF entry removes the change indicator from a TST after the required modifications have been completed. It does not change the fare, the taxes, or the passenger associations โ it simply clears the flag that tells the system the TST was edited.
This keeps the PNR clean and prevents unnecessary warning messages during subsequent ticketing or reissue processing.
Remove the Change Flag from a Single TST
When the PNR contains only one TST, enter the command on its own:
TTF
This removes the PNR change flag when only one TST exists.
To target a specific TST, add the TST number:
TTF/T2
This removes the PNR change flag from TST 2 only, leaving other TSTs untouched.
Remove the Change Flag from Multiple TSTs
To clear the flag from selected TSTs, list them separated by commas:
TTF/T2,4-6
This removes the PNR change flag from TSTs 2, 4, 5, and 6.
To clear the flag from a continuous range, use a hyphen:
TTF/T2-4
This removes the PNR change flag from a range of TSTs from TST 2 through TST 4.
To clear the flag from every TST in the PNR:
TTF/ALL
This removes the PNR change flag from all TSTs in one entry โ useful after bulk edits or restructuring across multiple ticket records.
๐ก Pro-Tip โ How to Verify the Change Flag Was Removed
TTF clears the flag silently โ there is no explicit “flag removed” confirmation in the entry response. To confirm the change actually landed, you must redisplay the TST and inspect it manually.
Recommended verification sequence
1๏ธโฃ TTF/T2 โ remove the change flag
2๏ธโฃ TQT โ redisplay the TST
3๏ธโฃ look for โ absence of the "change" indicator
4๏ธโฃ TQTC โ cryptic view if the flag is not visible
5๏ธโฃ ER โ save the transaction
What “flag removed” looks like
- The TST display no longer shows the change indicator (
For equivalent field). - No warning message appears when you run further pricing or ticketing commands.
- The TTH history shows the flag-removal entry as the latest action.
Rule of thumb: If you cannot clearly see the flag is gone after TTF, do not proceed to TTP. Re-run TTF, redisplay with TQT, and confirm again. Flag-related warnings at ticketing can block issuance entirely.
When to Use TTF
Use TTF when a TST has been modified and you need to remove its PNR change flag, either for a single TST, selected TSTs, or all TSTs. Typical scenarios include:
- After updating fare, taxes, or penalties in a TST with TTK or TTI.
- After splitting or adding passengers with TTS or TTA.
- Before proceeding to final ticketing to avoid flag-related warnings.
- After completing a reissue or exchange that modified the TST.
- When clearing the change flag across all TSTs in a group PNR.
How TTF Fits Into Your Ticketing Workflow
A typical ticketing session using TTF might look like this:
- Retrieve the PNR and modify the TST as required with TTK or TTI.
- Review the change with TTH to confirm the update was applied correctly.
- Enter
TTF/T2,TTF/T2-4, orTTF/ALLto clear the change flag. - Redisplay the TST with TQT to confirm the flag is gone.
- Continue with pricing, reissue, or ticketing with TTP as needed.

Frequently Asked Questions
What does TTF/T2 do?
It removes the PNR change flag from TST 2, leaving other TSTs in the PNR untouched.
Does TTF change the TST itself?
No. TTF only removes the change indicator. It does not alter the fare, taxes, or passenger associations in the TST.
How do I clear the flag on every TST?
Use TTF/ALL to remove the PNR change flag from all TSTs in the PNR.
How do I confirm the change flag has been removed?
Redisplay the TST with TQT after running TTF. The change indicator should no longer appear on the TST display. For additional verification, use TTH to review the TST history โ the flag-removal entry should be the most recent action.
Is TTF required before issuing a ticket?
If the TST has been modified and the change flag is still set, yes โ TTF should be run before issuing with TTP. Otherwise the system may reject the issuance or warn about an unresolved change.
What is the difference between TTF and TTH?
TTF removes the change flag from the TST so the record is clean. TTH displays the history of changes made to a TST โ it does not modify anything.
Conclusion
The TTF command is a small but important step in Amadeus TST management. It clears the PNR change flag that marks a TST as modified, returning the record to a clean state before ticketing or further processing. Use TTF for the only existing TST, TTF/T2 for a specific TST, TTF/T2,4-6 or TTF/T2-4 for selected or ranged TSTs, and TTF/ALL for all TSTs at once. Paired with TTS, TTA, and TTH, TTF completes the TST toolkit and ensures your ticket records stay accurate and error-free.
