Pan Am became a worldwide brand because it constantly led the line in airline operations. The Clipper services in the interwar period gave the luxury cruise ship experience with aircraft speeds. Pan Am also introduced the naval-style crew uniforms that remain industry standard today. In the jet age, the company was the first to adopt revolutionary aircraft like the Boeing 707. Pan Am blended this technological edge with some of the best staff and amenities in the market, with routes to all continents outside the poles.
