Over the next few weeks I will be flying America West a number of times. I will not fly enough to get any rewards and it is unlikely that I will fly with them again.

What other airlines programs earn points on America West flights ? Is any one better than any of the others ?

Or is it better to get America West and use it on the other airlines that they cover?

I already have Air Canada, Continental and American FF cards but none of these cover America West.
