In August 1945, Mid-Continent inaugurated new extension service from Tulsa to New Orleans, Louisiana, with intermediate stops at Fort Smith, Arkansas; Texarkana, Arkansas/Texas and Shreveport, Louisiana. Seven months later in March 1946, the company began stopping at Mason City, Iowa, on its Des Moines to Minneapolis route and in July 1945, service was added at Muskogee, Oklahoma, on the Tulsa to New Orleans flights. During wartime service, the company had discontinued service at Aberdeen, Bismarck/Mandan and Minot as well as St. Joseph, Missouri. In September 1946, all service was restored to these destinations.
