Established in 1967, PT DERAYA was a pioneer in the field of aviation business in Indonesia. It is a private company group with the synergy of various divisions and solid subsidiary companies that has succeeded in the world of aviation.

In 1971 PT DERAYA together with Arizona Air Services International from America formed a new partnership company by merging the names of the two companies to become PT DERAZONA AIR SERVICE. This partnership focuses on the business of leasing helicopter services (rotary wing).

PT DERAYA owns and operates several kinds of aircraft in all different sizes. Because the flight industry demands such high standards of safety control and maintenance,the highly skilled technicians of the Engine Maintenance Division of PT DERAYA carry out routine and thorough aircraft maintenance checks. This division also replaces the old aircraft with newer planes on a regular basis.

In 1972, for the first time in Indonesia, PT DERAYA set up a special school for prospective pilots by the name of DERAYA FLYING SCHOOL. Located in Halim Perdanakusuma Airport, DERAYA FLYING SCHOOL has turned out thousands of pilots who work in all facets of the airline business, both locally and internationally.

In 1976 PT DERAYA expanded itsenterprise by introducing a new business unit to serve the needs for chartered air transport, also known as commuter service, in the districts of Java, Sumatra, Isles of Riau, Kalimantan and Papua.
