PSA Airlines (OH, Dayton James M. Cox) has cancelled some 2,800 flights due to a week-long technical glitch which affected the American Airlines subsidiary's crew scheduling system, USA Today has reported. The carrier has already stabilised its systems but is only expected to return to the full schedule on June 21.

The meltdown started on June 14 and mostly affected flights departing from Charlotte International, although some flights out of each of Washington National and Philadelphia International were also cancelled. The irregularities spiked during the weekend, stranding thousands of passengers at the airport.

The effects of the technical issues were aggravated by high load factors on all flights, which meant that there were not enough empty seats to rebook all stranded passengers.

Although the glitch did not affect the parent company nor any other carrier operating under the American Eagle brand, they all suffered from spillover effects due to the irregularities for connecting passengers.

PSA Airlines, a fully-owned subsidiary of American Airlines, operates around 800 flights per day on behalf of its parent, some 12% of the entire network. According to the ch-aviation fleets module, it operates a fleet of 129 Bombardier Aerospace regional jets, including thirty-five CRJ200s, forty CRJ700s, and fifty-four CRJ900s.
