British Airways canceled all flights from London's Heathrow and Getwick airports scheduled before 6 pm, after a global computer system outage caused massive delays and left planes stuck on runways. Earlier on Saturday, there were reports of BA staff telling disgruntled passengers trying to get away for the Bank Holiday weekend that the company was under cyber attack but this was denied by the airline.

Passengers who were already at the airports were angry with the resulting chaos:
"Still on the tarmac at Leeds. #britishairways reckon Heathrow is so backed up we can't set off. No way we'll make our Vegas flight," one passenger David Raine wrote on Twitter.
Another, journalist Martyn Kent, wrote: "Sat on plane at Heathrow for hour and a half now. @British_Airways Captain describes IT problem as 'catastrophic'."
Passenger Roshni Burt, who was flying from Heathrow to Bahrain with her young son, said there was no news about when her flight would depart.
"When we left the check-in area there were angry people, people getting frustrated that their flights were coming up or near to departure, people getting turned away ... with BA staff basically saying 'if you've not checked in online, you've missed your flight'," she told Sky News.

Following initial reports that the ground halt was the result of a computer hacks, British Airways refuted media claims that the outage had been caused by a cyber attack, saying that there was no evidence to support that.
The problems, which passengers said were had affected flights across Britain, came on a particularly busy weekend with a public holiday on Monday and many children starting their school half-term breaks.
BA became the latest airline to be hit by computer problems. Last month Lufthansa and Air France suffered a global system outage which prevented them from boarding passengers. Passengers trying to catch planes in Britain on Saturday reported long delays at check-in desks and flights being held on runways.
