I&#x27;ve taken quite a lot of flights where there either was no business or first class or, if there was a business class, it was only marginally more expensive than cattle^weconomy class. Traveling through South America for 14 months now, the average economy seat is about 80USD per hour of flight if bought directly at the airport. How do they make a profit if your calculation is correct? (And I am not talking about the probably heavily subsidized regional airlines that get you from one jungle airfield to another and are the only means of getting to lots of places.)
