The return is trickier. But if you're willing to not worry about the upgrades on that flight it shouldn't be much trouble.
Thanks for the info. Yeah, I was thinking the outbound would be easier, and I only have enough AC eupgrades to upgrade one direction, so I'll aim for the outbound to credit the AC segment to AC. Not too fussed about the return, so I'll likely end up crediting the return to UA.
