During the late 1950s and early 1960s Six was the airline industry's leading lower-fare advocate. He predicted that increased traffic, not higher fares, was the answer to the airline industry's problems. To amazement from the industry he introduced the economy fare on the Chicago-Los Angeles route in 1962. He later pioneered a number of other low or discount fares which made air travel available to many who could not previously afford it. One of Continental's early innovations was a system-wide economy excursion fare which cut the standard coach fares by more than 25%. Continental took delivery of the first of five 707-124s in spring 1959, and started Chicago-Los Angeles nonstop on June 8. Having so few jets, Continental needed radical innovations to the 707 maintenance program. It developed the "progressive maintenance" program, which enabled Continental to fly its 707 fleet seven days a week, achieving greater aircraft utilization than any other jet operator in the industry. Six, not being satisfied with 707 service, introduced innovations and luxe cuisine on Continental's 707 flights which were described as, "... nothing short of luxurious" by the "Los Angeles Times", and, "... clearly, the finest in the airline industry" by the "Chicago Tribune".
