2. Newark acted as the East Coast terminus of the Air Mail
Air mail service has been available since 1918. The first airmail service started at Belmont Park in Queens and finished on the Washington, D.C. Polo Field. After Newark Airport established the first airport post office, mail traveled increasingly through this northern New Jersey industrial town.
Acting as the East Coast terminus of Air Mail, Newark was the most active landing strip in the United States during the 1920s and 1930s. Since then, other airports have surpassed it in air traffic, but mail continues to flow through the airport. FedEx is one of the airports largest tenants.
