What’s the problem at Gatwick Airport and which flights will be cancelled

In an unprecedented move, Gatwick Airport has ordered airlines to cancel dozens of flights because of sickness among air-traffic controllers – which is currently running at 30 per cent of the available staff.

Cancellations, diversions and delays have happened frequently this month due to staff shortage at Nats, which runs the control tower.

Aircraft movements will be capped at 800 per day at the Sussex airport, which normally has the busiest runway in the world.

Gatwick Airport says: “The daily cap will prevent last-minute cancellations and delays for passengers while Nats work through challenges driven by sickness and staffing constraints.

As the biggest airline at Gatwick, easyJet will bear the brunt of the cancellations. British Airways, Ryanair, Tui, Vueling and Wizz Air are expected to be among other carriers whose schedules will be affected.

The airlines will lose revenue and must pay for customer care, even though the cull is beyond their control.

The Independent estimates that 25,000 passengers will be notified in the next few days that their flights have been cancelled.

These are the key questions and answers.

For weeks sickness among air-traffic control staff employed by Nats at the Sussex airport has intermittently triggered a slowdown in the “flow rate” of arrivals at, and departures from, the busiest runway in the world. The latest problem is an outbreak of Covid.

With fewer flights able to land, disruption quickly takes hold – with cancellations, diversions and delays increasing as the day goes on.

The economic and emotional price of such disruption is high: costing airlines hundreds of thousands of pounds in passenger care, and wrecking holiday, family and business trips.

To try to reduce the chaos caused by on-the-day cancellations, Gatwick has imposed a cap of 800 movements (arrivals and departures) per day. That is the maximum number that the airport believes can be comfortably handled given the current staffing challenges.

The expected movements on Tuesday and Saturday, 26 and 30 September, are 800 movements – so no cancellations are anticipated.

On other days the excess is as follows:

The total is 164 movements, which corresponds to 82 round-trips from Gatwick. Assuming an average load of 150 passengers per affected flight, around 25,000 passengers will shortly find out their flights have been cancelled.

Airlines will be told how many flights they must take out of their schedules on each day when the cap applies. After that, it is down to the carrier to decide which flights to cancel. They are likely to be chosen on the basis of:

Airlines are likely to calculate which flights to cancel in date order: so Thursday’s cancellations are likely to be announced on Wednesday afternoon, with later dates following.

Under European air passengers’ rights rules, airlines that cancel flights for any reason must provide alternative transport as soon as possible.

If, for example, easyJet cancels a flight from Gatwick to Rome, and has no other availability to the Italian capital on the day of travel, passengers can ask to be rebooked on British Airways from Heathrow or Ryanair from Stansted.

Should a hotel stay be necessary, the airline is required to book and pay for rooms, as well as meals, until the passenger reaches their destination.

Passengers whose trips are rendered pointless by a cancellation can obtain a full refund for the affected flight. If another leg (outbound or inbound) has been booked on the same ticket, it is refundable too even if that flight goes ahead.

No, since these enforced cancellations are clearly beyond the airline’s control.

That is the hope. But airline sources say they are concerned about by the general lack of resilience in the control tower at Gatwick. It is believed that 40 days have been affected by staff shortage since the beginning of the summer.
