To apply to ANA or one of it subsiduary companies it must be through a crewing contract company, (due to Japanese pilot union issues I think). PARC and HACS are the main ones but there are others. While I only have experience with one of them, they are both customers of ANA so there packages cant be that different, maybe just the way they structure them.
Applications are online, and there published requirements are ABSOLUTELY inflexible. There seems to be a lot of recruiting activity across all ANA fleets at the moment. Hope that was some assistance to those interested.
