Well FT'ers, I'm getting hitched soon and I was wondering if we booked a C-Class seat with LX (long haul), what are the chances of a lovely upgrade to F? Or, will we be treated like the same?

I remember hearing stories from back in the days that people received complimentary upgrades during these occasions?

I'm guessing as the saying goes here 'nothing is for free in Switzerland', the same will apply to LX....
