Amadeus SX — Cancel Seat Requests from a PNR

A complete guide to the Amadeus SX command — how to cancel seat requests from all segments or specific itinerary segments in a PNR.

⚡ Key Takeaways

SX cancels seat requests from a PNR — either all segments or specific ones.
Use SX alone to clear every seat request in the booking, or SX/S5-6 for selected segments.
List non-consecutive segments with commas — for example SX/S2,4,6.
Essential before Group PNR name changes, aircraft changes, and reissues that alter the itinerary.
Cancelling seats removes the assignments — always confirm with the customer and reassign afterwards.

Advance seat requests are one of the most useful services an agent can provide, but they also become an obstacle when the itinerary changes. When a passenger is rebooked, when a name is corrected, when an airline changes equipment, or when a schedule change moves the flight to a different aircraft, existing seat assignments may become invalid — and in some cases they block further changes altogether. The Amadeus SX command is the entry that removes seat requests. It allows you to cancel all seat requests in the PNR, or just those tied to specific segments.

What Does the Amadeus SX Command Do?

SX is the Amadeus GDS command used to cancel seat requests from a PNR.

Category: Advance Seat Request.

The Amadeus SX command allows you to cancel all existing seat requests or remove seat requests for specific itinerary segments.

Because seat requests are linked to specific segments in the PNR, they must be cleared before certain actions can proceed — most notably name changes in group PNRs, rebooking when the aircraft changes, and reissues that alter the itinerary. SX is the correct tool for removing them cleanly.

Amadeus SX Command — Cancel All Seat Requests

The simplest form of the Amadeus SX command clears every seat request in the PNR. Use it when the entire itinerary needs a fresh seat selection — after a full rebooking, or when preparing a Group PNR for a name change.

Cancel all seat requests in the PNR:

SX

This cancels all seat requests in the PNR. Use it when the entire itinerary needs a fresh seat selection, or when preparing a Group PNR for a name change.

Amadeus SX Command — Cancel Seat Requests for Specific Segments

When only part of the itinerary has changed, the Amadeus SX command lets you target specific segments — keeping the seat requests on the other flights intact.

Cancel seat requests for segments 5 through 6:

SX/S5-6

This cancels seat requests for segments 5 through 6. Other segments keep their existing seat requests.

Cancel seat requests for non-consecutive segments:

SX/S2,4,6

Non-consecutive segments can be listed with commas to remove seats from specific flights only.

When to Use the Amadeus SX Command

Use the Amadeus SX command when you need to remove existing advance seat requests from all segments or from specific segments of a PNR. Typical scenarios include:

Preparing a Group PNR for a name change (seat items must be cleared first).
Rebooking onto a different aircraft where the original seats no longer exist.
Changing the itinerary so that seat assignments are no longer valid.
Removing seat requests after a schedule change that moved the flight.
Clearing seats on a segment that has been rescheduled to a different time.
Reassigning seats when the customer changes their seating preference.
Resetting the PNR before issuing new seat requests after a change.

How It Fits Into Your PNR Management Workflow

A typical PNR management session using the Amadeus SX command might look like this:

Retrieve the PNR and confirm that seat requests are present.
Identify which segments need to be cleared.
Enter SX to cancel all seat requests, or SX/S5-6 for specific segments.
End the transaction to save the change.
Proceed with the original action — rebooking, name change, or reissue.
Reassign seats after the change using the appropriate seat request entry.

Amadeus SX Command — Quick Reference Table

Command	What It Does
`SX`	Cancels all seat requests in the PNR
`SX/S5-6`	Cancels seat requests for segments 5 through 6
`SX/S2,4,6`	Cancels seat requests for non-consecutive segments

How the Amadeus SX Command Relates to Other Seat and PNR Commands

The Amadeus SX command is part of the seat and PNR management toolkit in Amadeus. Here is how it relates to the others:

SX → cancels seat requests from the PNR.
ST → creates seat requests for specific segments and passengers.
SM → displays the seat map for a specific flight segment.
RH → displays the PNR history, including seat request changes.
RP → changes the responsible office and related office assignments.
TTE → deletes TSTs from the PNR when restructuring the booking.

The key distinction: the Amadeus SX command clears existing seat requests. To rebook seats after a change, use ST and SM to select new seats on the modified segments.

Important — Confirm Before You Clear Seats

Cancelling seat requests removes the assigned seats from the PNR. If the segments remain on the same flights and aircraft, the seats may be lost and will need to be requested again. Always confirm with the customer before running the Amadeus SX command if the assignment was already confirmed.

If the itinerary is changing, clearing seats is standard practice — but the agent should be clear about what will be lost and what will need to be rebooked. Reassign seats using the seat request entry once the itinerary is final.

Frequently Asked Questions About the Amadeus SX Command

What does the Amadeus SX command do?

The Amadeus SX command cancels seat requests from a PNR, either for all segments or for specific segments.

What does SX/S5-6 mean?

SX/S5-6 cancels seat requests for segments 5 through 6, leaving seats on other segments intact. It is one of the most useful variations of the Amadeus SX command.

Why do I need to cancel seat requests before a name change?

Because seat items are linked to the passenger name. The system blocks the name change until the seat requests are removed, which is why you receive the error CANCEL SEAT ITEM OR SPLIT PNR PRIOR TO NAME RE-ENTER. Running the Amadeus SX command clears the seats and allows the name change to proceed.

Can I restore seats after cancelling them with the Amadeus SX command?

Yes, but you will need to make a new seat request using the appropriate entry after the change has been completed. The original seats may or may not still be available.

Can I cancel seats on some segments but not others?

Yes. The Amadeus SX command supports both range and comma-separated entries — for example SX/S5-6 for segments 5 through 6, or SX/S2,4,6 for specific non-consecutive segments.

Conclusion

The Amadeus SX command is the correct way to clear seat requests from a PNR in Amadeus. Use SX to cancel all seat requests in the booking, or SX/S5-6 for specific segments where only part of the itinerary has changed.

The Amadeus SX command is essential before certain actions such as name changes in Group PNRs, aircraft changes during rebooking, and reissues that alter the itinerary. Because cancelling seats removes the assignments, always confirm the change with the customer and reassign seats afterwards when the itinerary is final.

Paired with ST for seat requests, SM for seat maps, and RH for PNR history, the Amadeus SX command completes your seat management toolkit and keeps your bookings accurate and ready for every change.
