I have always earned miles on my air that I book thru RSSC, but I think that they have StarAlliance as their favored carrier. I always have checked to make sure it is registered. But I usually book on my own at a better rate and then I am assured that I do. For Alaska on MUSH, I am going to see what shakes out. On my first trip there, I booked on my own, and paid for hotel cause they couldn't get us there in time. Next time when I took the family, I took RSSC air and they paid for hotel the night before the cruise. Have no idea what coming into Vancouver is like. I have always come into Anchorage, which is a little more difficult. Have to see the Vancouver schedule for next August.
