Air Miles

Seems like my air miles from Narita to Toronto wasn't added in my ANA mileage club.
And now I remember I also have Air Canada's Aeroplan... So I guess I can choose either ANA or Air Canada to put my air miles. Seems like I have just enough air miles to fly domestic with ANA. So if I wanna change my air mile plan, this is a good time.
hmmm, what should I do... I guess I need to check their website.
