Your itinerary is fairly YQ-friendly as the only airline that you're flying that aeroplan charges YQ for is TG (and a short LH leg). UA, LX, TK all don't have YQ (for now).
Based on ITA, your first itinerary would be ~$680, and your second would be ~$520.
Thanks, dinosims. I'm trying that method on ITA, but can't get those particular flights to show up. I'm going through the multi-destination tab, and plugging in RDU-HAN, HAN-ATH, ATH-RDU and can't find those flights. Am I missing something?
