which is the best program to exchange miles

[Frosty]

I like NWA. I get have received more free upgrades with them than any other gold card that I had! Even when I only had a silver card they would often give me free upgrades.

I never see them fly with empty seats in Business Class, they fill those seats with free upgrades for their elite members.

My vote is for NWA.
