Flights Canceled Amid Global British Airways Computer Outage: What's Going On?

In September a year ago BA apologized to passengers for check-in delays caused by operational glitches that delayed flights at Gatwick and Heathrow, in a repeat of a similar incident that affected London-area flights for the airline last July.

"We are working hard with BA to reunite passengers with their bags as soon as possible and are sorry for the inconvenience caused".

Many passengers are still waiting for information on when their flight might eventually depart, but at the moment things still seem hazy.

Around one quarter of Sunday's flights set to depart from London's key hub before 1.00pm (1200 GMT) were cancelled as the airline battled to contain the "knock-on disruption" to schedules, with aircraft and crews out of position around the world.

BA CEO Alex Cruz said the company believes the "root cause" of the system failure was related to power supplies and that there was no evidence of a cyber attack.

Heathrow officials said they were working with British Airways, which is based in the airport's Terminal 5, "following an issue with their IT system this morning that has caused some delays for passengers".

In July and September, issues with the airline's check-in systems caused global delays and long lines.

As well as a bank holiday weekend in the United Kingdom, the timing also coincides with the start of the half-term holiday for many people.

Due to the vast disorder and inconvenience, British Airways is offering its customers full refunds or a rescheduling option, according to BBC News.

Further, British Airways advised passengers to not come to Heathrow to collect their delayed bags, as they were in the process of being sorted for onward distribution in secure airside locations.

Following severe backlash from angry customers, who were stranded at the airport due to the cancellations, the airlines urged its passengers to avoid coming to the airports unless they have a confirmed booking for Sunday.

"We apologise for the current IT systems outage".

Alma Saffari told the BBC that her flight from Marseille to London had been grounded.

British Airlines representatives repeatedly apologized for the problem on its Twitter account - which did not go down with the other system, and thus hosted a barrage of complaints throughout the day.

One passenger, British journalist Martyn Kent, said on Twitter: "Sat on plane at Heathrow for hour and a half now".

The problem comes on a holiday weekend, when thousands of Britons are travelling.
