ANSWER: Your father-in-law evidently was a pilot for American Airlines. As the captain of the plane, he would have logged more flying hours than his co-pilots. Back in 1939, flights over long distances took many hours compared to those of today, so he could have easily amassed a million miles or more.
It seems that American Airlines chose to award its loyal, long-time pilots with something to commemorate their years of service. In this case, they gave your father-in-law a Bulova Montgomery watch from 1938, inscribed on the back “American Airlines, Million Miler,1939,” along with his name.
American Airlines had contracted with the Bulova Watch Company to be their official timekeeping company. This particular model was a popular one in the Art Deco style, however, it originally had a leather band with three horizontal groves running its length which accentuated the design of the watch case, itself.

The Golden Age of Flight might be defined as the period extending from the first flight by the Wright Brothers to about 1950 or so. Items in this category are more out of the mainstream than those in the airline collectibles category—and naturally are harder to come by.

When the early airmail routes began offering seats for traveling passengers, they often included free meals or refreshments to tempt big-spenders away from traditional rail transport. Full meals were first served during the 1930s on china made by well-known companies like Wedgwood, Hall, Syracuse, Royal Doulton, and Homer Laughlin. These sets, designed to be lighter than household dinnerware, often included the airline’s logo or name in their graphics.


Many aviation collectors are former employees of the airlines. They would have had easy access to some of the materials, especially when things like maps and timetables needed to be updated. Old ones would have been thrown in the trash. Uniforms also needed to be updated from time to time, so older ones would again have had no use.
Collectors also favor certain defunct airlines, like Eastern, People, Braniff, and especially TWA and Pan Am. Pan Am was the trendsetter for the first half of the history of the airline industry. It was the first to offer long-distance, trans-Pacific travel on its Clippers and set the standard for design and style throughout the industry.
