Hi, I have been a loyal flyer of American Airlines for many years, but now wish to "look around" and see if I have been missing out on anything!

I have found, with much excitement, that the OnePass program has a very generous reward chart. For example, flying from the States to Asia costs only 50k miles, as opposed to 70K on AA Partner, CX. AA itself only flies to NRT at 50K.

As I will be flying a lot between Canada and Europe/Asia within the next few years, I wish to select the FF program that best suits my needs, and at this time it seems that OnePass is a good choice.

How is CO's network to Europe and Asia? And is NorthWest WorldPerks membership somehow equivalent to and interchangeable with OnePass since they are rather close partners?

With AA Platinum, what's the likelihood of getting comped on CO? I want to transfer all my flights to CO immediately, and not have to start from scratch.

Thanks for any help!
