Got Grease Monkey??
Install this little ditty:

Then go here:
https://www.ana.co.jp/asw/AMCTopServlet?type=e
Click on the Award Reservation link on the menu there and then look in the top left corner. You should see a link that says "Click for *A Search" that should take you to the *A search form. You might get an error about session expired. If you do just click on the link/button to the home page and go to ANA Mileage Club again and to Award Reservations again. It usually works but occasionally gets that session timeout issue.
Any feedback you have is welcome.
