Thanks for the feedback everyone!

I know there's a 15% off coupon for Asia "floating" around in the flyertalk world and am trying to get my hands on it before Sept 30. A pre-req is that the fare has to be > $800. So, I may fiddle with the itinerary a bit to get it to >800 and then apply the coupon. If that fails, I just go with the airfare.com deal.

Oh, plat, thanks for introducing me to ITA. I never heard of it before ... you always learn something new on this site ... such a great online community!
