First, Boeing aimed to improve their travel experience for the ultimate customers, the passengers. As compared to the traditional material (aluminum) used in airplane manufacturing, the composite material to be used in the 787 (carbon fiber, aluminum and titanium) would allow for increased humidity and pressure to be maintained in the passenger cabin, offering substantial improvement to the flying experience. The lightweight composite materials would enable the 787 to fly nonstop between any pair of cities without layovers.
