At Six's insistence, Continental (with Pan Am and Trans World Airlines) was one of the three launch airlines for the Boeing 747. On June 26, 1970, Continental became the second carrier (after TWA) to put the 747 into U.S. domestic service. Its upper-deck first class lounge and main deck "Polynesian Pub" won awards worldwide for the most refined cabin interior among all airlines, as did meal services developed by Continental's Cordon Bleu-trained executive chef, Lucien DeKeyser. Continental's 747 services from Chicago and Denver to Los Angeles and Honolulu set the standard for service in the western U.S. On June 1, 1972, Continental's widebody DC-10 service began. Six had insisted that Continental place a large order for DC-10s with manufacturer McDonnell Douglas. This decision again proved prescient, since the publicity associated with Continental's splashy 747 service Chicago-Denver-Los Angeles-Honolulu had stimulated increased market share and increased traffic for all carriers. Denver, Houston and Seattle were growing rapidly in the 1970s; the DC-10s took over most flights between Denver and Chicago, Los Angeles, Houston and Seattle, and between Houston and Los Angeles.
