More than 1,000 people spent the night at Narita airport outside Tokyo because of the computer shutdown that halted Delta Air Lines flights worldwide.
Flights were resuming Tuesday morning at Narita, but Delta spokeswoman Hiroko Okada said some more delays were expected.
Narita is the Asia-Pacific hub for Delta and several other U.S. airlines, so multiple flights arrive from the U.S. and then fan out to destinations in much of Asia.
The shutdown, triggered by a power outage at a Delta facility in the U.S., stranded many passengers in Japan. Six flights were cancelled, affecting 1,733 travellers, Okada said. Another 15 flights were delayed. The shutdown happened Monday afternoon, so many of the delays stretched overnight, forcing many more to find a place to sleep.
Katsuaki Tomimura, a spokesman at Narita airport, said more than 1,000 stayed overnight in an arrival lobby at the airport.
