Amadeus ETK Command: Save, Update Codes & File

A complete guide to the ETK command in Amadeus — how to end the transaction, update advice codes, and file the PNR in a single entry.

Ending a transaction is not always as simple as saving and moving on. When a PNR contains segments that were waitlisted, requested, or added with an inactive status code, the transaction must also refresh the advice codes so the airline can process the booking correctly. The ETK command handles both tasks in one entry. It ends the current transaction, updates the applicable advice codes on the affected segments, and files the PNR — completing the session without bringing the record back on screen. This guide explains what ETK does, its syntax, and when it should be used.

What Does the ETK Command Do?

ETK is the Amadeus GDS command used to end the transaction, change advice codes, and file the PNR.

Category: PNR Management.

It ends the current transaction, updates the applicable advice codes, and then files the PNR.

The three actions happen together. ETK saves the changes made to the PNR, refreshes the status codes on the affected segments so the airline sees the correct state of the booking, and closes the transaction. Unlike ERK, ETK does not redisplay the PNR — it simply completes the session and returns to the command prompt.

Syntax

Enter the command on its own while the PNR is open:

ETK

This ends the transaction, saves the changes, updates the advice codes on the affected segments, and files the PNR. The record is closed without being redisplayed.

When to Use ETK

Use ETK when you need to end and file a PNR while changing its advice codes. Typical scenarios include:

Filing a PNR after correcting segment statuses or advice codes.
Completing the transaction on waitlisted or requested segments that now need their status refreshed.
Filing a booking without reviewing the PNR again on screen.
Saving the PNR after multiple segment modifications that require advice code updates.
Finalising a transaction when you are confident the changes are correct.
Handling high-volume sessions where an extra display is unnecessary.
Completing the session after a rebooking or schedule change that altered the segment statuses.

How ETK Fits Into Your PNR Management Workflow

A typical session using ETK might look like this:

Retrieve the PNR with RT and review the segment statuses.
Make the required changes to the itinerary or segment advice codes.
Review the PNR on screen to confirm everything is correct — this is the last chance before filing.
Enter ETK to end the transaction, update the advice codes, and file the PNR.
The session closes and the changes are saved on the record.
If you need to verify the result, retrieve the PNR again with RT or review the history with RH.

How ETK Relates to Other End-of-Transaction Commands

ER → ends and saves the transaction, then redisplays the PNR.
ET → ends and saves the transaction without redisplaying the PNR.
ERK → ends the transaction, updates advice codes, and redisplays the PNR.
ETK → ends the transaction, updates advice codes, and files the PNR.
EF → ends the transaction and files a split PNR.
ERX → confirms AXR cancellation and redisplays the records.
ETX → confirms AXR cancellation and files the records.
IR → ignores the current transaction and redisplays the PNR.
IG → ignores the current transaction without redisplaying.

The distinction matters: ER saves and redisplays, ET saves and files without redisplaying, ERK adds the advice-code update and redisplays, and ETK adds the advice-code update and files. Use ETK when you do not need the PNR back on screen.

Important: ETK saves and files the transaction permanently. If you want to review the PNR after updating the advice codes, use ERK instead — it performs the same actions but redisplays the record so you can check the result.

If something was entered incorrectly and should not be saved, use IR to roll back and redisplay, or IG to roll back without redisplaying. ETK cannot be undone once filed.

Frequently Asked Questions

What does the ETK command do in Amadeus?

ETK ends the transaction, saves the changes, updates the applicable advice codes, and files the PNR.

What is the difference between ETK and ERK?

Both update advice codes when ending the transaction. ERK redisplays the PNR afterwards, while ETK files it without bringing the record back on screen.

What is the difference between ETK and ET?

ET ends and files the transaction without updating advice codes. ETK also refreshes the advice codes on the affected segments.

When would I need to update advice codes?

When segments are waitlisted, requested, or added with an inactive status code and the status must be re-sent before the PNR can be processed correctly by the airline.

How do I verify the PNR after using ETK?

Retrieve it again with RT, or review the changes with RH to confirm the advice codes were updated.

Conclusion

The ETK command is the combined end-of-transaction and filing tool in Amadeus. Use ETK when you need to save the transaction, update the applicable advice codes on the affected segments, and file the PNR — all in a single entry without redisplaying the record. It is the correct choice when the PNR has been reviewed and is ready to be filed, particularly on bookings where segment statuses needed refreshing after a waitlist, request, or rebooking. Because ETK files the transaction permanently, always confirm the PNR is correct before entering it — if you want to see the result on screen, use ERK instead. Paired with ER for saves with redisplay, ET for simple filing, EF for split PNRs, IR and IG to discard changes, and RH for reviewing the history, the ETK command completes your PNR management toolkit and keeps every booking accurate from the first entry to the final save.
