Once you have it (Platinum status here). Its very difficult to give it up. First class upgrades, dedicated phone lines, free drinks......
Yep. When I traveled my best {worst} year was over 300,000 miles with one airline and over 100,000 with my second choice.
I got "free stuff" but my body paid for it, and I never knew what time it was or where I was {kinda like slow joe}.
Since I retired, I haven't been on an airplane, and have zero desire to do so, ever again.
Been to every continent except the Antarctic {don't care} and now I stay in the USA and drive or go by train.
