airmail routes
Postal flight corridors
Airmail routes are designated flight paths for carrying mail by aircraft.
The term evokes the early days of aviation, when governments established specific corridors connecting cities for postal service: The first transcontinental airmail route linked New York to San Francisco.
Now largely historical, as modern air cargo operates through broader commercial networks.
