The Eight-cent Prexie
Domestic air mail use
The domestic airmail rate was eight cents per ounce from March 26, 1944 until October 1, 1946.
A cover sent airmail from Saint Louis to New Orleans in 1945.
Postage was payable on penalty mail sent airmail. This example was sent by the Navy in 1944. The sender must have been inside the United States or they could have availed themselves of the six cent military concession rate.
The eight-cent rate applied to airmail between Alaska and the lower 48.
There is no sign of censorship on this envelope used in 1944. I am unclear as to when censorship of mail between Alaska and the states ended.
The eight-cent rate applied to interisland airmail in Hawaii. This cover was flown from the island of Oahu to Kauai in June of 1944.
Domestic postcards did not get their own airmail rates until January 1, 1949. The airmail rate was eight cents for one sent by air from March 26, 1944 until October 1, 1946. This card was mailed January 1, 1945.
Well past the Prexie period, domestic airmail again became eight cents per ounce from January 7, 1963, to January 7, 1968. Even though the Statue of Liberty eight-cent stamp had been introduced in 1954 the eight-cent Prexie was produced into 1959, and one was still available four years later when this airmail letter was sent.
