I searched for the fare on Kayak and according to Kayak it was available for $696 including taxes on Orbitz, ANA's site, and Cheaptickets.com.
When you click on the link to ANA's site it gives an error message: "Cannot display booking at this time."
Orbitz displays the flight options and the fare but when you click to book one it displays: "We're sorry, due to changes in availability, we're unable to confirm your selection with the airline. Please make another selection."
Cheaptickets.com also shows the flights options and $696 fare but when you try and book it the error: "We're sorry, the fare for that itinerary is no longer available. The fare for that trip is now $1,061.70" comes up.
Unfortunately ANA appears to have caught on to the fare error and corrected it. To bad they caught it before I could book it.
Better luck next time!
