While its not to US, this has just proved very useful for me to go to Japan at Xmas. I've been looking for flights to Japan on Boxing day without much luck. Had found (and booked) SYD - KIX (via SIN) on SQ but was costing just over 130K plus just over $1K in real money one way for 3 people (2 savers, 1 standard) and that's with a 19 hour layover in SIN. And thats for Y!
Have now booked us 3 seats in First Class on JAL, SYD - NRT for 180K plus $249. Seems a much better deal plus gets us there a full day earlier. The only downside was that I now need to get NRT to Kyoto (since I already have accomodation booked and paid) and for some reason AA could not see internal flights available until the 28th. But my daughter tells me internal flights are cheap (at least on Peach or Jetstar) and I'm OK with a LCC on a 1 hour flight, or could use Avios (4500 points plus 1 pound each).
Very happy, possibly not the best use of my points but very good price for a peak period. (Oh and by accident first time I looked I forgot to set for redeem awards, this priced at $18k!!).
