A few US cargo airlines use new or recently built aircraft to carry their freight, but most use older airplanes that normally would not be certified to fly passengers anymore, like the Boeing 707, Douglas DC-8, Ilyushin 76. Examples of the 60-year-old Douglas DC-3 are still flying around the world carrying cargo. Short range turboprop airliners such as the Fokker Friendship and British Aerospace ATP are now being modified to accept standard air freight pallets to extend their working lives. This normally involves the replacement of glazed windows with opaque panels, the strengthening of the cabin floor and insertion of a broad top-hinged door in one side of the fuselage.
A number of cargo airlines carry a few passengers from time to time on their flights, and UPS once unsuccessfully tried a passenger charter airline division.
These cargo airlines, amongst many others, have importance in the history of air cargo:
The CargoAirline Association can be traced back to 1948, when the Air Freight Forwarders Association was formed to protect the members of the newly formed air freight forwarding industry from overregulation by the Civil Aeronautics Board and, to some extent, from the practices of the airline industry.
This form of representation continued for almost 30 years - until the air cargo industry was deregulated in 1977 and air freight forwarders became free to operate their own aircraft.
Today, the Association has a total of fifteen all-cargoairline members and has expanded Associate Membership to include airports that generate a significant amount of air freight and other industry members with a stake in the air cargo marketplace.
Cargoairlines (or airfreight carriers, and derivatives of these names) are airlines dedicated to the transport of cargo.
Larger cargoairlines tend to use new or recently built aircraft to carry their freight, but many use older aircraft, like the Boeing 707, Boeing 727, Douglas DC-8, Ilyushin Il-76.
