Over 100k for work is farily common which is why there is so much knowledge being shared here on FT.

I think it would be more interesting to ask "Who here has flown more than 100,000 miles in the past 12 months for non-work purposes ?
I suspect the answer might surprise you too. After all, all those FF miles have to be redeemed after all.

I have over 110,000 miles this year but only 70k are for pleasure. Have done 50-75k in the past 2/3 years for vacation travel but I suspect that is measley compared to others here.

However, I would note that people get more holidays in the UK and Europe compared with the US to facilitate all these flights.
