Thanks guys!! Air Canada's Aeroplan sounds like a really good thing for me, I shall join with them!! It's good that all points with AC don't have expire date, and it's easy to get to the next level, wowwww!!! What a program！！ But just wondering how does AIR NZ's program survive? In New Zealand, there are just so many kiwis use AirNZ's program!!!
Thanks again guys!
