Is there way I could change my tickets to CO or UA? If I can should I try? Is it worth it?
You will need to pay mileage redeposit fees and possibly new booking fees, and it all assumes there would be upgrade availability. It's worth looking for availability (please read the extremely long and detailed thread on using US miles on *A awards which will answer most of your questions) but it's a moot point if UA/CO are not giving up any seats. The redeposit fee is $150 (not sure if that is per ticket or per itinerary, and not sure if you'd incur extra processing fees on top of that). Personally I don't find CO or UA domestic F to be $150 better than US but everyone's got a different opinion! Also if you got a "saver" or "low" award then you might need to pony up some more miles to get the partner award. Another thing to factor in.
