Air transportation is the activity of taking merchandises from one location to another by using aircrafts. Air transportation was initially developed only for passengers, but thanks tú the introduction of aircrafts and cargo containers, the volume of cargo transported by air increased and continues to grow year after year. It is also the fastest mode of transportation and it is specially recommended when short transit time is required. Air transportation covers long distances and is specially useful for the transportation of perishable products or items of high value although its cost is higher than other modes of transportation.
