Delta latest to cancel flights for safety inspections

Delta Air Lines says it plans to announce Thursday whether it will cancel more flights while engineers inspect two types of planes in its fleet.

Chris Kelly, a spokeswoman for the airline, told CNN that Delta canceled several flights Wednesday, but she could not provide an exact number.

Delta became the second airline to cancel flights Wednesday because of inspections. American Airlines canceled 200 flights -- nearly 10 percent of its schedule.

Delta is inspecting the wiring of 117 MD-88 and 16 MD-90 aircraft. The airline says the checks are voluntary and are expected to be completed by week's end. American Airlines, meanwhile, is examining wiring secured to the MD-80 aircraft.

In Atlanta, the Delta cancellations caused grousing among passengers who missed job interviews, connecting flights and the comfort of their beds, CNN affiliate WXIA reported.
