Parks had its rights revoked, Ozark won not only the routes it previously applied for, but others as well. Parks merged into Ozark and Ozark (then without any airline operations) took over the Parks operation and the single route over which Parks had recently started service, thereby launching Ozark. Ozark over time became a jet carrier with a hub in St. Louis. In 2001, TWA was merged into

Pre-certification

Ozark Air Lines was incorporated on 1 September 1943 in Missouri by Laddie Hamilton, Barak Mattingly and Floyd Jones with $100,000 in paid-up capital. Ozark flew from

Civil Aeronautics Board The Civil Aeronautics Board (CAB) was an agency of the federal government of the United States, formed in 1940 from a split of the Civil Aeronautics Authority and abolished in 1985, that regulated aviation services (including scheduled passe ...

(CAB). The CAB was the now-defunct federal agency that, at the time, tightly regulated almost all air transport in the United States. Without certification from the CAB (or, in some cases, flying solely within a single state as an

), no airline could operate. When the CAB ruled in that case in December 1947, Ozark was shut out.

Parks Air Lines

One of the winning airlines in the Mississippi Valley Case was Parks Air Transport, controlled by aviation entrepreneur Oliver Parks, best known for his prominent role in developing pilot training. This was the third case in which PAT won routes, leaving it with the largest portfolio of feeder routes in the country, one that was regarded as potentially the "richest" such in the industry. But Parks failed to start service on his network and in June 1949, the CAB started proceedings to potentially revoke the certification of his airline, now called Parks Air Lines (PAL). As part of those proceedings, the CAB accepted applications for airlines to take over PAL's routes and Ozark renewed its application. The CAB came to a final decision in July 1950, revoking PAL's certification and awarded Ozark not only PAL's Mississippi Valley Case routes, but also those PAL routes from the Great Lakes Area case. In June 1950, PAL finally started flying a route from East St. Louis to Chicago via St. Louis and three central Illinois cities. An appeals court said PAL could keep operating this one route until the effective date of the CAB order (September 26, 1950) but would not prevent the CAB from enforcing the order while PAL pursued a full court case. PAL agreed to sell its airline operation (including five DC-3s) to Ozark in exchange for 37.5% of the business. Ozark had no airline operations at the time, so PAL's operations became those of Ozark and in this way, Ozark Air Lines started service on that one Chicago route on September 26, 1950. Ozark retained operations at PAL's

Jets

In 1961, Ozark's network reached from Minneapolis to Nashville and from Kansas City to Indianapolis and Louisville. Denver was added in 1966 and, in 1969, the network sprouted eastward: Ozark was awarded nonstops from Champaign and Peoria to Washington Dulles, continuing to New York LaGuardia. Atlanta was added in 1978 and four Florida cities in winter 1978–1979. In September 1966, Ozark and Central Airlines announced plans to merge, subject to CAB approval; the new airline was to retain the Ozark name and would be one of the largest local service carriers in the U.S. However, in November 1966, the two airlines announced that merger talks had ended by mutual consent due to financing difficulties. By 1967, the Martins and F-27s were replaced with Fairchild Hiller FH-227s, a stretched F-27; Ozark was all-turbine after the last DC-3 flight in October 1968. Ozark's introduced its first jets in July, 1966 with the Douglas DC-9-10s. The DC-9-10s were later augmented with McDonnell Douglas DC-9-30s (DC-9-31/32) and McDonnell Douglas DC-9-40s. The airline also ordered two Boeing 727-200s but never took delivery. In late 1980, Ozark retired its last FH-227 prop aircraft and went all jet with an all DC-9 fleet. Several very small cities including Burlington, Fort Dodge, and Mason City in Iowa, Decatur, Marion, and Quincy in Illinois, and Cape Girardeau, Missouri, briefly saw DC-9 jet service before Ozark discontinued serving those cities in 1982.
