Charter, also called air taxi or ad-hoc flights require certification from the associated country's regulating body such as the FAA in the U.S. The regulations are differentiated from typical commercial/passenger service by offering a non-scheduled service. In the U.S. these flights are regulated under FAA Part 135. There are some cases where a charter operator can sell scheduled flights, but only in limited quantities.
Private charter flights offer a range of advantages for busy professionals, including time-efficiency. From quicker check-ins to faster transit times, private jet hire is the perfect way to fulfil multiple meetings in different cities, carry out several site visits in one day or simply have more of an opportunity to remain productive while travelling.
