hi,
in my exp. in munich, they are checking status and booking class.
i everytime tried to go through the normal eco line, because they are often faster or less crowded. 3 times, i was told to use the 1st / business line, as i had status or a business class ticket etc.
i even tried to tell them, i dont want to use the priority line, but they told me to go to the more crowded line
anyway, this is only a personal xp.
anyway, a friend of mine is HON too, and he told me that he was bumped on a flight last time, but received a very high compensation.
so HON is nice as a status, but i think until lufthansa has established the service worldwide on a same level, it will not help you much more than being Senator.
but i am sure lufthansa will take care of that.
