I'd like to pose this question another way, if in 03 I expect to fly 150K total with at least 75K allocated to CO to keep my plat (this is something that I prefer to do), would I be better off trying to get 50K on AA or UA and the other 25K on DL or another carrier? Being IAD based, UA seems to make sense but something makes me lean towards AA. I'd be curious as to what others would think.
