WESTMORELAND COUNTY, Pa. — Flight resumed Sunday at Arnold Palmer Regional Airport in Westmoreland County, but extra precautions will continue to keep passengers and employees safe. Spirit Airlines is back up and running after suspending all flights about a month ago. The sole commercial carrier at the airport stopped service after bookings dropped dramatically, causing the airport to lay off 60 of its employees. Executive Director Gabe Monzo said extra safety measures will be taken to prevent the spread of the virus, starting with increasing the frequency of cleaning routines. Spirit is expected to resume mid-day flight from Latrobe to Orlando, Florida, on Sundays, Mondays and Thursdays. The airport is anticipating more flights to return eventually.
