In December 2013, Sky King furloughed/laid off nearly half of staff across all departments and returned one airplane to the leasing company. As of December 31, 2013, Sky King had two airplanes in its fleet, one of which had been grounded for several months with a bad engine that needed to be replaced. Also in December, the New Jersey Division of Gaming Enforcement revealed that Sky King owed $23,424.26 in taxes to New Jersey from 2009, thus prohibited from doing air charter business with Atlantic City casinos.
