I am trying to maximize the miles and wonder if there is any way to find out the booking class on LH before the tickets are actually bought?
This is the information provided for a ARN-FRA-GDN trip, and as you can see it only stats "Business Saver" which from my knowledge can be anything like J, P, Z etc. As J grants twice the miles vs P it would be nice to know the class beforehand.
I've tried to use the ITA Matrix to find out but I guess I don't have the necessary skills that it requires.
Anyone who knows a way to find out?
