Så här står det på SAS extranät för resebyrår, som är måttligt skyddat för utomstående, angående passagerare som har uppgraderat via OT:
Irregularity
Rebooking procedures for passengers with an upgrade, affected by irregularity:
Rebooking to other SK-flight
If the same booking class as passenger was upgraded to is available - rebook the passenger in the upgraded booking class.
If the same booking class as passenger was upgraded to is not available - rebook the passenger in the same service class as originally booked and refund the upgrade.
Rebooking to other airline
Rebook the passenger in the same service class as originally booked and refund the upgrade.
Note: In case of refund in above cases, passenger himself must contact Optiontown and request refund.
