HI *A experts.

I'm northwest millionmiler, and familiar with skyteam, but don't have a clue about the star alliance. In need of som advice for my brother who is about to start commuting heavily on SAS.

My brother is currently a scandinavian base member, with very few miles in the account. but he's about to start on a new job that will have him taking about 35 roundtrips a year between oslo and copenhagen on SAS. In addition let's say that he'll fly around 15,000 BIS miles on 6 segments. 2/3 of his trips will be bought relatively far in advance, (restricted fare).


here's the questions:

What *A program should he join to maximize miles?

What *A program should he join to gain access to lounge priveleges?

What *A program should he join to gain first class upgrades on his commuter trips?

What other factors should he consider?

Are there advantages or disadvantages of flying SAS metal and not being a sas program elite member?

Any advice would be greatly appreciated.

Thanks!
