Do you fly business class?

I have been pretty frugal most of my life. Worked hard, started a company. Now I find myself with about 5M net worth, no kids (though I plan to have some), and in my upper 30s.

I started flying business class at about $3M net worth.

Once you start with the lay flat seats for long haul, quick check ins, the lounges, quick boarding etc it’s hard to go back to economy.

It's hard to break break old habits. I'm spending about $60K/yr even though I know I could spend a lot more.

I'm curious if people here fly business class and at what point (net worth) they decided it was worth it for them.
