British Airways flights in chaos as another IT failure strikes

Tens of thousands of British Airways passengers encountered long delays and possible missed connections after another major IT failure.

In one example, flight BA365 from Lyon to Heathrow remained on the ground in France for two hours 40 minutes, rather than the expected one hour.

The three evening departures from Manchester to Heathrow all arrived at least two hours late, jeopardising connections to destinations such as Abu Dhabi, Cape Town and Rio.

The airline’s website, ba.com, and its app also failed for a time – with a message reading: “We are experiencing high demand on ba.com at the moment.”

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.

Many passengers flying into Heathrow in order to transfer to departing overnight flights are likely to miss their connections. For example the early evening flights from Edinburgh and Glasgow, due in shortly before 7pm, were…
