The UA website will not show you COPA routings if UA has an alternative. For example, when I book IAD-MDE, the UA site will not show COPA's IAD-PTY-MDE routing. The exception to that rule is if you look up award travel instead of paid tickets.

I would look on Hipmunk or Orbitz. Find a routing that includes both airlines and call COPA to see if they can book it for you if you want the 25% PQM bonus. However, the COPA agent cannot apply the GPU. You will have to call UA separately to do that. If you want to use GPU's, any UA metal must be W or better.

I've never done it myself, since I don't have the patience for all of that.

I don't think that COPA has a 24 hour policy like UA. At least, I have never seen anything in their published materials that says so.
