British Airways canceled all flights from London’s Heathrow and Gatwick airports scheduled before 6 pm (local time; 5 pm GMT) on Saturday due to a global computer outage, Reuters reported.

The airline advised passengers against coming to the airports as it would not be able to help them.

British Airways refuted media claims that the outage had been caused by a cyber attack, saying that there was no evidence to support that.

Earlier, the company posted a tweet recognizing the problem.

The official Twitter account of Heathrow Airport, the busiest airport in Europe, reported that there was an issue.

Passengers who had already arrived at the airports were less than pleased with the chaos that had erupted there.

British Airways is the latest airline to be facing grave IT issues. Last month, Germany’s Lufthansa and Air France suffered a global system outage which prevented them from boarding passengers at the time.
