I was poking around Google Flights for a friend and noticed that there's quite a few dates in Autumn with super cheap economy fares to Tokyo from New York. Normally these would be in the $1000-$1300 range but these are as low as $489! Most of the cheap fares seem to be on Air China via Beijing or ANA/United via Chicago or Los Angeles, and both have reasonable layover times. If it were me, I'd take the ANA itinerary because of ANA's stellar reputation . As far as Business Class fares go, there's a few Air China itineraries for $2100, but from the reviews I've read , the food and service is terrible, so that $2100 is to get you a lie-flat seat and not a whole lot else. Keep in mind that the arrival of Tokyo's fall weather lags New York's by a month, so the weather should be mild and pleasant on a lot of the Oct and Nov dates... $489 via Beijing on Air China Click to enlarge or $627 on ANA/United Click to enlarge My Japan tips are here .
