> I don't understand why the cursory math of someone with no domain knowledge, business understanding, or access to accurate data is at all interesting
The post is similar to many things you read online (on HN or other places) it's really just 'infotainment' and it doesn't really matter if it's accurate anymore than a Netflix series might be.
Generally even articles by people that have domain knowledge can be just compounding of early errors or assumptions they make.
'Napkin math' though is always interesting because it would lead you to believe that if the numbers you are using don't make sense there is probably something you aren't considering that you need to think about.
I had the same reaction -- I don't follow the industry much but know that Business class accounts for an outside proportion of revenue and profit for the airlines... which doesn't seem to be addressed at all.
