Norwich Airport Closes for Multiple Periods Due to ATC Staff Sickness Amid Ongoing Industrial Action

Norwich Airport announced three separate closure periods on 3 September during which aircraft could not take off or land, citing a combination of air traffic control staff sickness and continuing industrial action that reduced its ability to find cover. The closures ran from 06:00 to 14:00, again from 16:00 to 16:45, and for a third period from 18:45 to 19:30. Airlines were informed of the closures, and passengers were advised to check directly with their carrier before travelling to the airport.

The disruption has already affected scheduled services. KLM flight KL1054 from Norwich to Amsterdam was cancelled, along with return flight KL1055 from Amsterdam to Norwich and the subsequent KL1056 from Norwich to Amsterdam. KLM is contacting affected passengers regarding rebooking arrangements.

The closures come less than a week after Norwich Airport was shut to all air traffic for an entire day on Friday, 28 August, during a 24-hour strike by air traffic control employees who are members of the Prospect union, part of an ongoing dispute over pay, terms and conditions. Today's disruption differs in that it is being driven by staff sickness compounding the effects of action short of a strike, which Prospect members have been taking since 17 August, including working strictly to contractual requirements, refusing non-contractually required overtime, refusing shift swaps, and withdrawing goodwill. Norwich Airport said it made an offer that included a 3.5% pay increase in April 2026, a further 3% consolidated increase from July 2026, and an additional 3% from April 2027, but the dispute has continued. Today's closures follow partial closures on 21 August and the full-day shutdown on 28 August.

This episode belongs to a broader category in which action short of a strike, rather than a full walkout, produces the more persistent disruption because it removes the informal flexibility that thin rosters depend on. Prospect had already warned that Norwich Airport's air traffic control operation ran with very low staffing levels and regularly relied on staff flexibility to maintain safe minimum coverage — once that flexibility is withdrawn, ordinary sickness absence that a fully staffed unit would absorb instead forces closures.

For an airport of this size, air traffic control coverage is a narrow, non-substitutable resource: there is no pool of spare qualified controllers to call in on short notice, so a single sick day during a labour dispute can matter as much as a rostered strike. The repeated pattern of partial closures on 21 August, a full-day shutdown on 28 August, and now three separate windows in one day shows the dispute compounding rather than resolving despite a pay offer already on the table.

What happens next depends on whether Norwich Airport and Prospect can settle the underlying pay and terms dispute, since the airport's own offer of increases in April 2026, July 2026 and April 2027 has not ended the action. Until a settlement is reached, staffing-dependent closures of this kind are likely to recur whenever sickness coincides with the ongoing action short of a strike.
