JAL Computer Error Cancels Flights, Strands 13,500

Japan Airlines Co., the nation’s second-largest carrier, said it’s investigating what caused a malfunction in its baggage-loading system that prompted it to cancel flights stranding 13,500 passengers.

“We are sure it’s not a cyber attack,” Jian Yang, a spokesman at the carrier, said by telephone in Tokyo. The airline had to scrub 166 domestic flights. No international services were canceled.

It’s the first time the carrier has experienced an issue with its load-planning system, which prompted staff to calculate baggage loading data by hand.

Larger rival ANA Holdings Inc.’s main carrier canceled 131 flights and delayed hundreds following problems with its check-in computer system in 2007. That prompted the airline to pledge as much as 300 million yen ($2.9 million) in investment.
