2000, service was added to Joplin Regional Airport in Joplin, Missouri, as a stop between Columbia and Dallas/Fort Worth. In early 2001, Ozark operated to the Taos Regional Airport serving Taos, New Mexico, from Dallas/Fort Worth on two days per week during the winter ski season. A year later, the company ceased operations and sold its assets to the now-bankrupt Great Plains Airlines, based in Tulsa, Oklahoma. Sales and marketing Reservations From the 1960s through the late 1980s, Ozark Air Lines' reservations department used a special toll-free WX telephone prefix in New Jersey which could be reached only in certain areas of the state by dialing 0 and asking the New Jersey Bell operator to connect to Ozark's WX number: WX-8300. The number could not be dialed directly by the customer and was only available to certain telephone exchanges where WX was available. (Direct-dial toll-free service made WX numbers obsolete, and they have been largely phased out.) Advertising In the late 1960s, comedian George Carlin appeared in Ozark advertising.
