Rudi:
I had another good look at BlondeBomber's comparison table. It's a great piece of work.
As far as mileage is concerned then most of my flights are Aust-Europe and trans-Pacific. Flight class: Lauda - C; TG - J,C; UA, LH, AC, ANZ, ANA and SQ - economy and discount economy. Annual mileage (roughly) 150-200k. Domestic upgrades are not that important to me as flying in internationally usually gives me the same class as the international segment.
BlondeBomber:
A few words from you but they have the value of gold!! Seems like I'll have to join UA and LH programs and then swap between them according to the class flown as Rudi does.
