A chartered flight is a private flight that allows you much more freedom as it lets you select the destination and the aircraft type depending on your requirement. Also, you can skip the long check-in lines and security pat downs, and enjoy a quiet, stress-free flight. With a regular flight, you are not only restricted to the schedule of the airliner but you also have to go through long lines to check in, undergo security screening, and deal with several restrictions about items that you can carry on board the airplane.
