This document summarizes the history and development of airline marketing from the early 1900s to present day. It discusses how airline marketing evolved from focusing on aviation as a novelty in the early 1900s using posters, to emphasizing speed and luxury in the 1930s-1970s as air travel became more common for businessmen. In the 1970s-1980s, marketing shifted to portray flight attendants as sex symbols. More recently, with the rise of low-cost carriers and online travel agencies, marketing has emphasized price and used social media advertising. The document traces how airline marketing has adapted to trends in the aviation industry and changing customer demographics over time.
