I'm looking at AA 280 ICN-DFW on Fri Sept 27 or Sat Sept 28. Friday is more convenient and a bit cheaper, but I'm wondering how much I'm sacrificing in SWU chances by going on Friday instead of Saturday. Any informed speculation? AA seat map shows 10 out of 30 J seats occupied on both days, but I guess that doesn't mean much this far out. I'm AA Plat (SWU would be a gift from a family member). I figure it will be a long shot either way.
