Agreed, the fares for my actual dates are all within $100 of each other, US included. Man I would love to go one way on CO and the other on *A since that's where I have status, but the price is not worth it unless someone here has any suggestions. Sux that CO goes *A the day after I fly. I also find it crazy though not surprising that an M fare on Delta with a mileage upgrade is the same price almost to the penny as just buying the discounted Biz fare outright....Man I see why so many people dislike ST, although getting someone who worked with me to check rather than forcing me through a script like the UA'ers in India was really refreshing!!!
