Just under 200k and I have never flown Biz. When I was younger and single, I couldn't justify the added cost of the seat against what that money could be used for at my destination. Even when i'm flying for work, and Biz is available, my employer will pay me cash to not take biz and i'll take that cash every single time.

While I may not enjoy the perks of unlimited drinks and extra meals in the air, I will retire a millionaire.
