British Airways could be facing a massive bill in compensation costs after thousands of its passengers were stranded by a global IT system meltdown.
The airline was forced to ground all flights from Heathrow and Gatwick on Saturday due to the system crash, causing chaos at both airports.
Under EU law, delayed passengers are eligible to claim compensation, unless the delay is caused by factors outside the airline’s control.
BA has said it believes the systems failure was caused by a power supply issue, after it found no evidence of a cyber attack.
Air travel experts say that could put the airline on the hook for major payouts to customers whose flights were cancelled or severely delayed.
Malcolm Ginsberg, editor-in-chief at Business Travel News has said that given the circumstances, he believes the airline will be facing a hefty bill.
“There is no question – the EU denied-boarding regulations will have to apply,” Mr Ginsberg told the Press Association.
“They have broken all the rules and they will have to deal with it – it’s going to be a very expensive situation for BA.”
He added: “The money doesn't really compensate passengers for the situation.”
A BA spokesman said: “We are continuing to work hard to restore all of our IT systems and are aiming to operating a near normal schedule at Gatwick and the majority of services from Heathrow on Sunday.
“We are extremely sorry for the huge disruption caused to customers throughout Saturday and understand how frustrating their experiences will have been.
“We are refunding or rebooking customers who suffered cancellations on to new services as quickly as possible and have also introduced more flexible rebooking policies for anyone due to travel on Sunday and Monday who no longer wishes to fly to/from Heathrow or Gatwick.”
How much the IT meltdown will cost BA in lost revenue and customer payouts is still up in the air.
Civil Aviation Authority guidance states that anyone who is delayed by more than three hours in getting to their destination could be entitled to compensation.
“Airlines are required to pay compensation to passengers when their flights are delayed or cancelled,” the CAA says on its website. “However, you only have the right to compensation in some circumstances.”
The authority says there are two key factors to determining whether you are eligible. The first is whether you have been “severely inconvenienced”.
“For instance, if you have only been delayed slightly, you may not be entitled to compensation,” the CAA says.
The other determining factor is the cause of the delay. “If the delay was caused by an ‘extraordinary circumstance’, you will not be entitled to compensation,” the aviation authority says.
In August 2016, thousands of Delta Air Lines passengers faced delays after a similar system-wide crash forced the airline to ground its flights.
Delta said it lost at least $100m (£78m) in revenue as a result of the outage, which occurred after an electrical component failed, cutting off power to the airline’s data centre.
A Heathrow spokesman said on Sunday morning that delays and cancellations of BA flights were expected to carry on through the day.
The airline admitted there would be “some knock-on disruption to our schedules on Sunday, as aircraft and crews are out of position around the world”.
Departure boards showed BA flights departing from Gatwick early Sunday morning, but several flights from Heathrow were still listed as cancelled.
