NEW YORK (Bloomberg) - AMR Corp.'s American Airlines returned to its regular flight schedule today as it completed the final inspections on its fleet of Boeing Co. jets.

More than 3,300 flights were canceled over five days, including 200 yesterday, and 360,000 passengers were stranded as American conducted wiring inspections and repairs on its MD-80 aircraft.

"Our American Airlines flight schedules are now back to normal," the carrier said today on its website. " We sincerely regret the inconvenience created by the cancellation of a portion of our flights last week resulting from the FAA-related inspections of our MD-80 fleet."

CEO Gerard Arpey said winning travellers' confidence again "will not be easy" after the cancellations linked to the MD-80s, which account for 46 percent of American's fleet.

"There is no sugarcoating the fact that we are going to have to earn back the trust of the customers we disappointed in recent days," Mr. Arpey said in a message to employees. He added: "I know we can do it."

AMR fell 39 cents, or four percent, to $9.48 on April 11 in New York Stock Exchange trading. The shares have plunged 71 percent in the past year and 32 percent since the end of December.

American parked the planes after Federal Aviation Administration spot checks found that wiring bundles in the jets' wheel wells didn't comply with an FAA order, even after inspections of the MD-80 fleet for the same issue in March.

Customers booked on canceled flights may request a refund, and those stranded overnight can seek a $500 voucher toward future flights, American said. Those with flight reservations through today can rebook without charge. The airline is paying for hotel stays for passengers stuck overnight.
