Sure there is. Do it once every 3 years. Simple math.

A sustainable level of CO2 emissions per person is 2.3 tonnes per year. This includes food, housing, clothing and transportation.

A 20 hour flight produces ~3 tonnes of CO2. This is ON TOP of the CO2 used up for living.

You haven't given the number of how much CO2 people use to live, only what the sustainable number is, so there isn't enough information to make any conclusion.

The current average in the US is ~16 tonnes per year, so around.

Sounds like that number just takes the CO2 that the us produces and divides by population. It would be agreeable if the wealth that came from that CO2 production did also was similarly distributed, but since it's not, that's not really how much your every day joe produces to live. It's what is produced to put another billion dollars onto a company's books.

Still, it’s produced and it’s produced because there’s demand.

But yes, I agree, the vast majority of CO2 is produced by corporations who don’t pay for the externalities they create.
