Here I just have to turn the microphone over to Lucky, and just quote verbatim, because this offer is just too good for anyone with a few Amex points who miay be flying to Japan.
Through the end of the year, ANA is reducing the number of miles required to upgrade from coach to business class. From New York to Tokyo one-way, for example, an upgrade will only be 14,000 miles instead of the usual 28,000 miles. Furthermore, the upgradeable fare classes are quite reasonable. I see $1,300 “S” class fares that can be upgraded under this promotion.
Amex Membership Rewards points transfer to ANA, so $1300 and 28,000 Amex points should be enough for a roundtrip business class ticket from the US to Tokyo on ANA. Not bad!
