I took the top 61 (i know, strange number but this is how many airports Wikipedia listed) largest airports in the USA and divided them by their population (metro area) and, as the title says, these are the top 10 cities with large airports for their size. If this quiz gets 25 plays I will also make a quiz soon for the cities with small airports for their size according to the same list.
PS... the list also included San Juan but i decided not to count it because it is debatable weather Puerto Rico counts as part of the US.
