New York to Tokyo, Japan $682 round-trip, nonstop, incl. all taxes

We came across a heap of great fares to Asia from United earlier today. Hong Kong, Tokyo, Ho Chi Mihn City, Beijing, Seoul...all ranging from $677 to $737 round-trip, incl. taxes, for travel in fall. Pretty good, right? We sure thought so! Ah, but then they were gone, just as quickly as they came. Sigh. That's how it goes in the game of airfares, but we do hope someone out there was able to snatch one of these fares!
