Am I correct in saying that I have to find C class seats available for me to use either miles to upgrade or eVIP's to upgrade? I don't see C class available anywhere at all. I also do not see U or X class available anywhere. So basically I'm just out of luck on AA, right?

When I look at other airlines I do not see what is upgradeable at all. For example, if I choose CX or BA as the filter, no class comes up as being upgradeable. How do I know what class to use for CX or BA?
