As the total area of the U.S. is large and the traveling distance between the different cities is very long, Air transport has become very popular among the travelers. This mode of transport is the fastest and simplest way of long-distance intercity travel in America. The journey from east coast to west coast takes approximately 6 hours while the journey from west coast to east coast takes approximately 5 hours.
Many cities in the U.S. are served by one or two airports. If you are living in a small town and want to travel by air, it is cheaper to drive to a nearby city served by a major hub airport and fly to your destination or conversely fly to a city which is closer to your destination and then rent a car to reach your town. However there are some small towns served by passenger air service, but you are aware that an air transport is very expensive so it is advisable to drive to the city with major hub airport.
