IAS Cargo Airlines

International Aviation Services Limited, trading as IAS Cargo Airlines from 1975, is a defunct wholly privately owned, independentBritish airline that was based at London Gatwick Airport in the United Kingdom. It commenced operations in 1967 and went bankrupt in 1980, following a merger with London Stansted based Trans Meridian Air Cargo (TMAC) to form the short-lived British Cargo Airlines.

International Aviation Services Ltd was an air transport consultancy formed in 1966. It commenced worldwide cargo charters from London Gatwick in 1967 with leased, second-hand Bristol Britannia 300F turboprop equipment. It began replacing leased equipment with its own aircraft in 1971, acquired its own air operator's certificate in June 1972 in the name of International Aviation Services (UK) Ltd and adopted the IAS Cargo Airlines trading name four years later.

IAS Cargo Airlines acquired additional, second-hand Britannia turboprop freighters as well as a Canadair CL-44 "swing tail" freighter during the early 1970s to expand its fleet in response to growing worldwide demand for its pure freight services.

When the world's major scheduled airlines began re-equipping their fleets with new generation widebodied jet aircraft from the early 1970s, a growing number of older generation, narrowbodied jet planes, such as the Boeing 707 and the Douglas DC-8, became available on the second-hand market at prices smaller airlines that were lacking the resources to invest in new equipment could afford.
