SK flights booked using miles/points from Star Alliance partner programs get assigned to the “Bonus” category.
SK’s minimum included baggage allowance for award booking class tickets is as follows:
1 x 23 kg: SAS Go/economy class
2 x 23 kg: SAS Plus/premium economy class
2 x 32 kg: SAS Business/business class
The eticket/receipt listed luggage allowance is too often messed up when it comes to mileage tickets for partner airline flights, so I don’t count on the eticket receipts.
