from What I understand, KE doesnt do this. You eith have to have purchased it at original booking or used miles to upgrade... as most of the routes they fly are very well flown premium route.. theres about a 95% chance that the flights going out fully booked out in all classes.....and if not in all classes... almost always up front....

Thanks for the help!
