Sky King (Lakeland) has filed for Chapter 11 bankruptcy protection on Friday, September 28 as the second US carrier on the same day following Southern Air (Cincinnati International). Sky King currently operates a B737-200 and four B737-400s on behalf of tour operators, casinos and the government. Sky King has blamed the bankruptcy of Direct Air (Myrtle Beach International) in spring 2012, one of its key customers for which it had operated scheduled public charter services, as one of the key reasons for the bankruptcy filing. It hopes to be able to restructure its debts and get better contracts from its suppliers to eventually reemerge from bankruptcy protection again.
