Ozark Airlines’ Air Mail Route 107 was extended to Dallas, Texas on October 1, 1969.

No official cachets were used at any of the offices involved.

This cover was one of only 125 pieces of mail carried on the inaugural Air Mail Route 107 flight from the Dallas, Texas Airport Mail Facility to Tulsa, Oklahoma (where it was backstamped) and is listed in the Contract Air Mail Flights (CAM) Section of The American Air Mail Catalogue as 107NE109f.

On October 26, 1986, Ozark Airlines was merged into the operations of Trans World Airlines. 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.
