Tens of thousands of British Airways passengers face delays and possible cancellations after another major IT failure.
Passengers at London Heathrow Terminal 5, as well as airports abroad, say they have been told communications systems have failed.
In one example, flight BA365 from Lyon to Heathrow remained on the ground in France for two hours 40 minutes, rather than the expected hour. It is now in the air but is likely to land over an hour late.
The airline’s website, ba.com, and its app also appear to be down – after repeated attempts by The Independent to access the site, a message was displayed reading: “We are experiencing high demand on ba.com at the moment.”
Problems began shortly after 5pm GMT. Some outbound flights British Airways from Heathrow have been delayed by up to two hours, including departures to Geneva, Larnaca, Vienna, Vancouver and Dusseldorf. The 6pm flight to New York JFK is expected to leave 90 minutes late.
Domestic flights to Aberdeen, Newcastle and Edinburgh are running an hour or more late.
Arrivals from Continental airports are typically being delayed by an hour or more.

His BA Airbus A319 landed on schedule at the Austrian capital from Heathrow shortly before 6pm, but left nearly two hours late.
With limits on the hours in which planes can depart and arrive at Heathrow, any disruption can swiftly lead to cancellations. In addition, the complex air-traffic control operation at Heathrow requires a steady flow of departures and arrivals in order to function properly.
Any “bunching” of flights can swiftly lead to widespread disruption.
British Airways has a long history of falling foul of IT failures. In May 2023 more than 200 BA flights were grounded, affecting over 30,000 passengers across a bank holiday weekend.
Even worse, over a bank holiday weekend in May 2017, during a routine systems upgrade, a switch was thrown that brought the entire BA Heathrow operation to a standstill. Hundreds of thousands of passengers had their travel plans torn up.
The Independent has asked British Airways for a response.
