You can recover uncredited points yourself in your personal account on the airastana.com website – Nomad Club – Account overview – Manage points – Claim Nomad points & Miles, or by following the link.
If corrections were made to the ticket, such as a passenger name correction at the airport or a forced rebooking due to a delay or cancellation of the flight, the ticket number may have been changed. In such cases, you can contact sales offices or the call center to clarify the ticket number.
If you were unable to recover the points yourself due to a website error, you can contact the Nomad Club department via the link, attaching a screenshot of the error.
Allow us to also inform you that for your convenience, we ask you to provide your member number during booking or at check-in for the flight. This way, if the booking class is appropriate, the points will be automatically credited to your account.
