Hi all, I have an ANA Business Class ticket from Haneda to Sydney next month. The menus get released the end of this month, it looks like. I've read online it's possible pre-order the Japanese meal (and perhaps even essential to do so, given that they sometimes run out). How far in advance, and how should I go about doing that on their website?

Thanks in advance, I've only ever flown ANA First Class before, where running out of food wasn't an issue!
