KLM in the 1980s
Koninklijke Luchtvaart Maatschappij – KLM (Royal Dutch Airline)
In 1980, KLM carried 9,715,069 passengers. In 1983, it reached an agreement with Boeing to convert ten of its Boeing 747-200 aircraft (Five 747-200Bs and five 747-200Ms) into Boeing 747-300s with the stretched-upper-deck modification.
The work started in 1984 at the Boeing factory in Everett, Washington, and finished in 1986. The converted aircraft were called Boeing 747-200SUD or 747-300, which the airline operated in addition to three newly built Boeing 747-300s manufactured from the ground up. In 1983, KLM took delivery of the first of ten Airbus A310 passenger jets. Sergio Orlandini retired in 1987 and was succeeded as president of KLM by Jan de Soet. In 1986, the Dutch government’s shareholding in KLM was reduced to 54.8 percent. It was expected that this share would be further reduced during the decade. The Boeing 747-400 was introduced into KLM’s fleet in June 1989 — WIKI
