As a private pilot, you can operate aircraft for personal use but cannot be paid to fly. You can fly the aircraft almost anywhere in the United States below 18,000 feet. A private pilot license can be obtained with a minimum of 35 flying hours.
As a commercial pilot, you can be paid to fly with certain exceptions. A commercial pilot’s license can be obtained at 190 flight hours and find employment doing aerial photography, crop dusting, banner towing, or go on to get an instructor's rating. Once you reach 1500 hours, you can apply for your Airline Transport Pilot License and fly for airline or cargo transport companies eventually making six-figure salaries.
