British Airways on Friday cancelled more than 175 flights as the fallout from an IT failure entered its second day.
BBC reports that most of the cancellations are for European and domestic flights, but there have also been delays to other services, while some passengers have been unable to check in online.
Meanwhile, traffic has started building up in Dover as delays are expected on roads and ports over the bank holiday and school half-term break.
On Thursday, BA apologised for the cancellations, saying it was related to “technical problems” causing difficulties with online check-in.
In a statement on Friday the company said: “While the vast majority of our flights continue to operate today, we have cancelled some of our short-haul flights from Heathrow due to the knock-on effect of a technical issue that we experienced yesterday.”
Those affected have been offered the option to rebook an alternative flight or request a refund, BA added.
The BBC understands that the technical issue has been resolved and should not affect flights on Saturday.
Data firm Cirium said Friday was expected to see the most departures from UK airports since before the Covid pandemic, with more than 3,000 flights planned.
This is partly down to families heading on holiday for the half-term break.
