Most domestic air passenger services do not carry freight as the configuration of services does not well correspond to the configuration of the freight demand. Further, domestic flights rely on narrow-body aircraft that are not designed to carry a noticeable number of air cargo containers. The exception is postal services, particularly between airports of more than 2 hours of flying distance. In the above photo, mail trays and bins are being loaded into the cargo hold of a domestic passenger flight (Boeing 737-800) between Miami (MIA) and New York (EWR).
