Ozark Airlines brought the Jet Age to another small community when it began McDonnell Douglas DC-9 service at Quincy, Illinois on August 1, 1975. 

No cachet was provided for the inaugural mail.

This cover was one of only 172 pieces of mail carried on the inaugural Air Mail Route 107 Jet flight from Quincy, Illinois to Chicago, Illinois (where it was backstamped) and is listed in the Jet Flights Section of The American Air Mail Catalogue as J-1829N.

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.
