Using the same airport, Austin and Albert Lea were added to Air Mail Route 107's Segment 11 on January 4, 1960 between Rochester, Minnesota and Mason City, Iowa.

Inaugural service to the new destination consisted of two daily roundtrips with different routings. The first northbound flight traveled from Mason City to Austin / Albert Lea to Rochester then terminating at Minneapolis / Saint Paul. The second northbound flight on the inaugural date traveled from Mason City to Austin / Albert Lea and then flew nonstop to Minneapolis / Saint Paul.

This cover was carried on the inaugural Air Mail Route 107 flight from Austin, Minnesota to Minneapolis, Minnesota (where it was backstamped) and is listed in the Contract Air Mail Flights (CAM) Section of The American Air Mail Catalogue as 107N91.

The Austin Postmaster autographed the cover.

On October 26, 1986, Ozark Airlines was merged into Trans World Airlines' operations. TWA had been Ozark Airlines’ primary competitor at its Saint Louis hub. At the time of the acquisition, the two carriers operated almost three-quarters of the flights to and from that airport.

In January 2001, TWA filed for a third and final bankruptcy and was acquired by American Airlines. American Airlines laid off many former TWA employees after the September 11, 2001 attacks. TWA continued to exist as an LLC under American Airlines until July 1, 2003. American Airlines closed the St. Louis hub later that year.
