Why are flights being cancelled?

A technical issue with Air Traffic Control yesterday afternoon resulted in widespread chaos, resulting in delayed and cancelled flights.

According to Cirium data, more than 1,500 inbound and outbound flights were cancelled yesterday, with more expected today.

How long could the flight problems last?

Airport delays could last up to a week due to a backlog of passengers and flights in the incorrect places after being grounded.

NATS Operations Director Juliet Kennedy warned it will take “some time for flights to return to normal”.

The Sun’s Head of Travel Lisa Minot said yesterday: “This is actually the busiest weekend since October 2019.

“The fact that it has gone on for so long means this is going to definitely start to impact flights all the way into next week.

“It’s going to impact flights across the globe.”

A number of UK airports have issued statements, with many warning to expect more delays and cancellations today – here’s the latest.

Heathrow Airport

Nearly 30 flights have been cancelled at London Heathrow today.

The biggest UK airport said in a statement: “Due to yesterday’s technical issues suffered by UK Air Traffic Control, there may be some continuing disruption on some routes, including flight cancellations.
