For next year I'm considering a trip to Norway. Now that SAS is earning 100% miles for US Airways Dividend Miles, I'm deciding between flying EWR to OSL on United or SAS. I'd appreciate any feedback from people on which airline is better on that route.

Also, does SAS give any benefits to Star Silver members?

One other thing I'm considering on my trip is to fly home from either Bergen or Tromso via Oslo, but I see the layover is only an hour in Oslo. Is that enough time at that airport? Would I have to get my baggage and re-check it to get back to the US?

Appreciate all the feedback in advance!!

Thanks!
