As far as the business class confirmed ticket you get every month, does it have to be on ANA or any other carrier can be a possibility? who choses the airline of commute, ANA or the pilots? I am thinking at the options for people commuting back to Europe, maybe using AF or LH might give better chances to get home early by leaving on the last day of duty in the late evening instead of waiting for the lunch time departure of ANA flights to Europe.
Thanks for the information
