Which of the following is a disadvantage of air transport?

A disadvantage of air transport is its high cost. Air transport is generally the most expensive mode of transportation due to its high operating costs. This is because airlines require specialized equipment, such as airplanes and airports, and have high maintenance and fuel costs. Air transport also involves additional costs, such as security measures and air traffic control fees. These costs are ultimately passed on to the consumer in the form of higher ticket prices or shipping fees. Therefore, while air transport is a fast and efficient mode of transportation, it may not be the best option for businesses or individuals with limited budgets. They may choose alternative modes of transportation, such as sea or land transport, which may take longer but are generally more cost-effective.
