AIRMAIL HISTORY:
Airmail began back in 1918 when airplanes were a fairly new invention. Through an air mail route, this was a promotion of universal commercial use of aeroplanes. This provided an affordable class to send mail. This class of mail was used domestically in the USA until May 1, 1977, after USPS announced that First-Class postage would buy the same or better level service. Airmail as a separate class of international mail ended on May 14, 2007, when rates for the international transportation of mail by surface methods were eliminated.
