Air transportation has a low patronage because it

Air transportation has a low patronage because it is costly. Air travel is generally more expensive than other forms of transportation such as road or rail. This is because the cost of operating and maintaining aircraft is high, and these costs are often passed on to passengers in the form of high ticket prices. As a result, many people cannot afford to travel by air, and air transportation tends to be used mainly by people who can afford it, such as business travelers or wealthy individuals. This limits the overall demand for air travel and contributes to its relatively low patronage compared to other forms of transportation.
