In the 1960s, the Jet Age introduced an era of sleek, streamlined airplane exteriors inspired by the modernist aesthetics and cutting-edge technology of the time. The interiors reflected a mid-century retro appeal characterized by vibrant colors, bold patterns, and a luxurious ambiance with spacious seating. In contrast, contemporary airplanes are primarily designed with efficiency, functionality, and technological advancement in mind. Today's aircraft prioritize fuel efficiency, passenger capacity, and in-flight comfort with lightweight materials, efficient layouts, and advanced in-flight entertainment systems.
