One question regarding the CO and UA miles: I still have to use them separately, correct? In other words, I still would have to have enough UA miles for one ticket independent from having enough CO miles for the other ticket because they don't "spill over" yet?
Correct.
Also, if you use miles from two different programs for the two tickets, put one ticket on hold, then call and book/ticket the other ticket, then call back and ticket the first. This way you avoid getting the first ticket only to find that the second seat disappeared in the few minutes it will take to call the second airline.
