Not all states have airports. Delaware is one of only a few states in the United States without an airport that operates regularly scheduled passenger flights. However, it has eleven airports of every kind, including military airports. There are several reasons Delaware may not have an airport for commercial use. The first is that it’s a tiny state with a population of more than 1 million. It is also situated between two cities, Philadelphia in the form of Pennsylvania and Baltimore, with both having big international airports. Thirdly, Delaware is well-served by public transportation services, such as Amtrak trains and buses. Although Delaware is the sole state with no commercial airfield, some states have an insignificant number of airports. For instance, Rhode Island has just seven airports, while Wyoming has just 122. Airports within an individual state are contingent on several variables, such as the size of the state, its population, geography, and economy. States with more significant populations and more diverse economies are likely to have more airports as they have to handle more air traffic and support more industries.
