I'm in the midst of my third DONE3 (from CAI) and planning a 4th as it is probably the most advantageous way to get home from Cairo. I am not sure how AA credits the flights on an Explorer fare. I've always ticketed them through AA's RTW desk. Does the whole trip then fall under the cost of fare x cabin bonus x status bonus? Or do they somehow sort it so the partner flights accrue LPs based on distance? If so, would you want to use AA code shares on shorter flights, partner codeshares on longer ones when available? Is there still an advantage to maximizing distance on partner flights? It's been so much less stressful "blowing" segments on getting to and from my "spoke" hometown--no worry about missing my nested flight to get to the hub.
