I posted this in the newbie specific thread which doesn't seem to get much traffic, so I'm posting here:

I just got a job as an analyst that will require me to travel quite a bit from Arizona (where I live) to Ireland in the next 5 months. Most flights are either BA or CO. I've just gotten my feet wet with two round trips to Ireland on BA, and now have about 23000 BA miles.

Ireland is only the first phase of my project, with subsequent phases in Kawasaki, Xiamen, Penang, and Porto Alegre (Brazil). I will be doing a lot of traveling, and want to maximize my return on points programs. Does anyone have a suggestion on which to choose?

Also, I will probably move to Austin, Texas in the spring (not sure if this changes which program would be best).

Thanks for your help!
