Expert mode for 1K?
I haven't been 1k since the old days of the GPU and either I have forgot how things worked or the codes are different nowadays. I am a 1k again and want to use my plus points for international upgrade from Y to J. When looking at flights on expert mode, for what fare code should I look for to get "instant" upgrades? how about for LH upgrades?
Thanks in advance.
