Airmail Service Flag

This month marks the 90th anniversary of the nation’s first regularly scheduled airmail service.

Shown here, the first airmail flag featured a pair of wings on either side of a globe. The globe indicates the Department’s intentions to develop the service not only nationally, but internationally as well according to the National Postal Museum's website.

In May of 1918, airmail service was limited to trips between Washington, DC, Philadelphia, and New York City. These flights used Army Air Corps pilots and borrowed airplanes. On August 12, the army pilots were replaced by post office pilots.
