British Airways was hit by a “technical issue” on Monday as frustrated customers around the world complained of delays.

Reports earlier on Monday suggested dozens of BA flights had been grounded after an IT failure hit the company.

In a statement, BA said: “Our flights are currently operating, but are experiencing delays as our teams work to resolve a technical issue affecting some of our systems.”

Later on Monday evening they released a further statement and confirmed the issue had been resolved.

“Our teams worked hard to resolve an issue we experienced for a short time earlier this evening,” it said.

“We’ve apologised to customers for delays to their flights and ensured they were able to reach their destinations as planned.”

A Heathrow spokesperson had said earlier on Monday: “We are aware of a technical issue that British Airways are investigating and we will be working with them to provide updates to passengers as soon as they are available.”

The spokesperson added that Heathrow’s systems were “operating as normal”.

BA’s X account could be seen replying and apologising to disgruntled customers on Monday evening.

One account posted: “@British_Airways cmon let’s have some updates pls on the pc outage. Stuck in vienna!!!!”

Another wrote: “@British_Airways what is happening with the load computing for aircrafts? Stuck on a plane in Rome going nowhere till the software is rebooted. Please assist!”

BA replied: “Our website is down. We are doing all we can to return online as soon as possible.

“Hopefully not too long before the Captain has his load sheet. Thanks for your understanding. Have a good journey when it is safe for you to be airborne.”
