Singapore Airlines, Alaska Airlines terminating their codeshare

In a message to its travel partners, Singapore Airlines (SQ) is advising that its codeshare with Alaska Airlines (AS) is being terminated.

The termination of the codeshare between the two carriers is effective as of Oct. 1, 2025 and all SQ*AS codeshare sales for departures beyond Sept. 30, 2025 have been closed.

AS will perform a schedule change on Sept. 6, 2025 for all bookings with SQ*AS sectors with departure dates from Oct. 1, 2025 onwards.

Travel agents should closely monitor disruption notifications through the applicable channels where the booking was made (i.e. email notification, GDS queues, OrderChangeNotification etc.), and perform the following for SQ-AS bookings:

If your NDC platform does not yet support involuntary servicing, please contact your local Sales Operations team for assistance.

• Refunds will be handled as per fare conditions

Agents are advised to contact their local Sales team if they have any queries.
