I think there are some good suggestions here. One thin that I have been eyeing for my little-used CO and AA accounts are inter-island flights in Hawaii. 5K RT on AA; 10K on CO.
Marathon man, you speak of simplifying your life with less PC use and fewer accounts to keep up with. Aren't you going through a lot of trouble to switch a credit card to a different idine account and then go out and order the right things from the menu to get you right at your award level? Doesn't seem overly simple, IMO.
