British Airways has said all of its short-haul flights from Heathrow are cancelled until midday today following “continuing technical issues”.

The airline said: “Customers due to travel later today should check their flight status on ba.com before coming to the airport as we anticipate further disruption during the day.”

It said its long-haul services at Heathrow and all flights at Gatwick and London City Airport are due to operate as planned, “but customers may experience some delays”.

The company added: “Our website ba.com is working and customers can check-in online and at the airport.

“We are offering customers on cancelled services options including a full refund and all customers booked to travel on short-haul services from Heathrow today can opt to rebook to a later date for free if they choose. We will be contacting customers proactively.”

On Friday evening, British Airways suffered a major outage, which caused several flights to be cancelled, but said that it was not due to a cyber attack.

The airline’s website and app were down for hours leaving customers unable to check-in online or book flights.

Passengers whose flights were cancelled will be offered a refund or rebook options.
