British Airways said its flights were gradually returning to normal on Tuesday after a still-unexplained computer problem disabled the airline’s self-service check-in kiosks for several hours at a number of global airports, causing significant delays.

The spokesperson declined to say how extensive the delays were due to the computer glitch, but travel tracker website Flight Aware lists that there were 261 British Airways flight delays as of 10:35 a.m.
The BA outage comes after Delta Air Lines last month suffered 2,300 flight cancellations, costing about $100 million in lost revenue, after a power-control module caught fire.
The spokesman told ATW that, while the problems had initially been limited to the USA, the delays to flights arriving in London had led to knock-on delays on other services.
ZDNet has reached out to British Airways and will update if we hear back.
It did not comment on social media reports of major delays at airports in San Francisco, Washington D.C. and Atlanta.
However, problems continued to affect a number of flights today.
British Airways logos are seen on tailfins at Heathrow Airport in west London, Britain, on May 12, 2011.
A DAA spokeswoman said three departing flights scheduled to London City were delayed by two hours, while another was cancelled with passengers transferred to another flight.
One passenger, Dana Al-Qatami, who was flying from Switzerland to London, was issued with a handwritten boarding pass on Tuesday morning.
Although he had managed his checked in online, he said that BA workers could not enter their computers to detect which passengers had passed through security.
The DAA has advised passengers to check latest flight information with their airline before travelling to Dublin Airport.
The second issue with the service this year might damage the airline’s reliability.
