JAL has just rolled out a new JMB award calendar search tool. Now you can search for awards in a calendar format for up to 330 days for international awards and 2 months for domestic awards! And it will display award availabilities on all flights from your airport! Before this enhancement, you could only search for international award using the calendar search features up to 180 days and 1 city at a time. Unfortunately, it is only available in Japanese right now. But even if you are only using the English version of JMB website, you also get an enhancing which allows you to use the calendar search for up to 330 days now . Details on how to do the award calendar search using the Japanese site can be found on my blog: http://jal-pak.blogspot.com/2011/11/searching-for-jal-awards-get-easier.html
Just a random search on C award availabilities during obon 2012 Results in this order: JFK ORD LAX SFO BOS YVR grayed out ones are inbound availabilities (N. America to Japan)
i just hope they implement something similar to NH's so you need to have some miles before you do a search. This is too handy for those who don't intend to redeem awards through JMB
