If you want to earn, one of the cheapest ways is to get yourself to TUN to position for the SV TUN-JED-BKK I fare which can be done for € <1,100 r/t. and earns you basic Silver status (Sky Team Elite level) if credited to Flying Blue (AF/KL - not as helpful if you are accumulating to SK) . Looks like earning SK Silver status would take at least two flights. Looks like getting to TUN from ARN in Y will run ~€300.

If you have an SK credit/charge card, you may want to stay with SkyTeam (which SV is a member) especially if it provides elite qualification, and QR and AY are not). Otherwise, drop the credit card and just be a free agent.
