The Douglas DC-3 is often called the airplane that changed commercial aviation. It was the first airliner that could reliably make a profit carrying passengers rather than depending primarily on mail contracts. American Airlines played a major role in its development, helping Douglas create a sleeper version that evolved into the famous DC-3.

​

The aircraft typically carried between 21 and 32 passengers and was staffed by a single stewardess. In those early years, stewardesses were often registered nurses and provided a level of personal service that became a hallmark of airline travel. Passengers enjoyed comfortable seats, hot meals served on china, and attentive service that helped make flying an appealing alternative to train travel.

The DC-3 helped establish American Airlines as a leader in passenger service and transformed flying from an adventure for a few into a practical transportation option for many. Nearly ninety years later, it remains one of the most influential aircraft ever built and a symbol of the beginning of the modern airline industry.
