Thanks for the info about the alliances. I hadn't figured that out yet. I stayed up pretty late last night and did some old fashioned research. It seems they're all pretty much the same. We just need to pick an airline as suggested.

One more question, since you all have been so helpful. How would it be a problem if UA and CO merge? I'm curious since CO would be my first pick. Would points possibly be lost?

Thanks so much for the help!
