Mike, The article did not specify the cost basis used, but it seems that when ever people in the airline industry talk about "direct operating costs" they are referring to "cost per seat mile". Obviously, more seats give a larger airplane an advantage by spreading the flights costs over a larger number of seats. Cost per seat mile does not address other concerns such as profitability.
