The Rhine and Main rivers have been a vital part of Germany's postal history, with the first airmail flights taking place in the early 20th century.
The Rhine and Main rivers were chosen for airmail flights due to their strategic location and importance for trade and commerce.
The first airmail flights were operated by Deutsche Luft Hansa, which later became Lufthansa, and began in 1919.
The airmail service initially connected major cities like Frankfurt, Mainz, and Koblenz along the Rhine and Main rivers.
The airmail service was a significant improvement over traditional postal services, allowing for faster and more reliable delivery of mail.
The airmail service also played a crucial role in facilitating communication and trade between cities and regions along the Rhine and Main rivers.
The airmail service was eventually standardized, with regular flights and routes established to meet the growing demand for mail delivery.
The airmail service was also subject to strict regulations and guidelines, including rules for mail packaging and handling.
Today, the Rhine and Main rivers continue to play an important role in Germany's postal history, with many museums and archives dedicated to preserving the history of airmail and postal services.
History of Flugpost

The first official airmail flight took place on June 10, 1912, with Ferdinand von Hiddessen at the helm.
Ferdinand von Hiddessen flew a Doppeldecker called the "Gelber Hund" (Yellow Dog), which was built by August Heinrich Euler, a pioneer in motorized flight.
The flight started at 19:04 from Frankfurt-Niederrad and took 13 minutes and 27 seconds to cover the 27 kilometers to Darmstadt, where a post exchange took place.
Hiddessen then continued to Worms with 79 kilograms of post, landing there at 21:00.
This flight marked the beginning of the Flugpostwoche (Air Mail Week) that took place from June 10 to 23, 1912, along the Rhine and Main rivers.
Special Flugpost-Karten (air mail cards) were created for this occasion, which had to be franked with a regular postcard stamp and an additional air mail stamp.
