A total of 100 Japan Airlines flights were canceled Thursday due to a glitch in its flight operations computers, affecting some 7,800 passengers.
The cancellations mostly involved domestic flights at Haneda airport in Tokyo. There were also delays of up to two hours and 15 minutes, with JAL’s international flights affected as well.
The glitch hit a system designed to automatically calculate the weight of passenger baggage to keep aircraft balanced, according to a company official. Following the problem, JAL staff made manual weight calculations to load the baggage.
