So I am on the opposite end of the scale. Those 1k's who pay waaay too much and never get the GS invite, because of company policies.
146575 eqm, and spend is 33,456 = 22.8cpm
I do have probably have another 19,500 eqm's to fly before the year end, and the cost is apx 7500~8000, so I may be on the cusp of GS spending, but only 1 C/D fare international this yr 1 - Z, and a bunch of domestic M/U/E and lower fares.
Lesson is, don't try and get to 1k the way that I have!
