This is no longer true any more, especially with US airlines perfecting FCM (first class monetization). I am 1K with UA, its top published tier, and I wish my upgrade was 50%.
I am a free agent, and my long game is million miler program with three different airlines in three different alliances. My current progress is 55%+, 30%+, and 20%+. I wish I had started out younger, but I am still young, and should accomplish all three within the next 10 years.
