Every Major Gatwick Airport Disruption in History: The Complete Travellers' Guide
Hero image · designer to drop in. Brief: see image slot 1 below.
⚇ The Situation
Gatwick has been disrupted, closed, shut down, snowed under and droned. The December 2018 drone event remains the worst single drone-caused shutdown in aviation history — three days, 140,000 passengers, 1,000 flights, no perpetrator ever found. Beyond that headline, Gatwick's disruption history reads as a more efficient, less-stressed version of Heathrow's — same volcanic ash, same snow, same BA IT outage, but with consistently faster recovery. This guide unpacks every major event and tells you what to do when the next one finds you.
Section 021. Why Gatwick disruption looks different from Heathrow
Before any of the incidents in this guide make sense, you need to understand Gatwick's defining operational facts.
One runway, used intensively. Gatwick has technically two runways but operates them as a single runway — the second is too close to the main runway to be used simultaneously, and serves only as a backup if the main runway is closed. In practice, every flight uses one strip of tarmac. By contrast, Heathrow has two parallel runways used in mixed mode all day.
One runway, but the busiest in the world. Gatwick extracts more movements per hour from its single runway than any other single-runway airport on the planet. In 2019, the airport hit a peak of 55 movements per hour on one runway — a level of efficiency that requires extraordinary operational discipline.
Lower hub-airline concentration. EasyJet is Gatwick's largest airline, but its share is around 40% — significantly less concentrated than BA's 50%+ at Heathrow. Add British Airways' Gatwick-based EuroFlyer subsidiary, Virgin Atlantic, TUI, Wizz Air, Norse Atlantic, Vueling and others, and Gatwick has a more diverse airline mix.
Different ownership story. Gatwick was sold by BAA in 2009 to a consortium led by Global Infrastructure Partners. GIP invested heavily in operational improvements through the 2010s. The airport is now owned by VINCI Airports (which acquired a majority in 2019). The ownership churn has, broadly, been positive — each new owner has invested in operational capability.
Less media attention. Gatwick is Britain's second-busiest airport, but the UK media's aviation reporting is heavily Heathrow-centric. When something goes wrong at Gatwick, it usually gets less national attention than the same event at Heathrow.
The cumulative effect: Gatwick's disruption events tend to be less catastrophic than Heathrow's, recover faster, and get less press coverage. The exception is the December 2018 drone event, which broke all of these rules.

Section 032. December 2018: The drone event that shut Gatwick for three days
If you read only one section of this guide, read this one. The Gatwick drone event of December 2018 is the most consequential single airport disruption in modern British aviation history. It changed UK drone legislation, drove a global wave of counter-drone investment, and remains — uncomfortably — an unsolved mystery.
What happened
Wednesday 19 December 2018, just after 21:00. A security officer at Gatwick reported seeing two drones near the airport perimeter — one over a vehicle, one over the perimeter fence. Within thirty minutes, six further sightings were reported, five of them from police officers. The airport's only operational runway was closed at 21:03.
For the next three days, the runway was reopened and reclosed repeatedly as new drone sightings were reported. Each time the airport prepared to resume operations, another sighting would force another suspension. By the morning of Friday 21 December, the airport had operated for only minutes across the previous 36 hours.
The cumulative impact:
- Around 1,000 flights cancelled or diverted over the three-day period.
- Approximately 140,000 passengers affected — directly stranded, indirectly delayed, or unable to begin journeys.
- The four busiest days of the Christmas travel season disrupted.
- EasyJet alone reported £15 million in costs from the event, having cancelled around 400 of its own flights affecting 82,000 passengers.
The drones were sighted at intervals across all three days, with reports continuing as late as 9 AM each morning before pausing during the day. The pattern suggested either a deliberate, knowledgeable operator — or a wave of false sightings amid heightened tension. Police later said they believed the original sightings were of an unauthorised drone, while some later sightings may have been of a police drone deployed during the response.
The investigation
Sussex Police led an 18-month investigation costing £800,000 and involving five police forces.
170 drone sightings were reported across the event.
115 were classified as "credible" by police.
Zero photographs or videos of the drone were obtained.
Zero physical evidence of the drone was ever recovered.
A reward of £50,000 was offered for information leading to arrest. Nobody claimed it.
Two local residents were arrested and held for 36 hours before being released without charge. They later received compensation for wrongful arrest.
In April 2019, Sussex Police suggested the disruption may have been "an inside job" — caused by someone with knowledge of Gatwick's operational procedures.
The investigation was closed in September 2019 with no charges and no identified perpetrator.
Some commentators have suggested the event may have been caused by mass panic rather than a real drone — pointing to the absence of any photographic or radar evidence, and the tendency of stressed observers to misidentify birds, balloons or police drones as the original threat. Sussex Police, as of late 2020, continued to maintain the disruption was "a malicious attack" by a real drone operator.
The honest position in 2026: nobody knows for certain what happened, who did it, or why. The event remains officially open as an unsolved case.
Why Gatwick's response was so slow
The post-event analysis identified several systemic problems with the response that have shaped UK aviation policy ever since.
No counter-drone capability. In December 2018, Gatwick had no operational counter-drone technology deployed. The airport had begun a drone detection programme in 2016, but no detection or neutralisation system was active. Industry analysts later noted that drone disruption had been "predictable, if not inevitable" — and yet no UK airport had effective counter-drone defences at scale.
Unclear command and control. The response involved Sussex Police, the airport itself, the Civil Aviation Authority, the Department for Transport, the Home Office, and eventually the British Army. The chain of command for who could authorise what response measures was unclear. The army was eventually deployed with "specialist equipment" (widely understood to be RF jamming and detection capability, though the exact equipment was not disclosed).
No tested playbook. The airport's risk register reportedly identified drones as a potential threat, but the response plan had not been comprehensively rehearsed. When the event occurred, decisions were being made in real time under extreme pressure.
Precautionary closure was the only safe option. Whatever the actual threat level, the safety risk of operating a runway with a possible drone in the vicinity was unacceptable. Each new sighting forced a fresh closure. The airport could not differentiate real sightings from false ones in real time.
What changed
The December 2018 event was the catalyst for one of the largest counter-drone procurement waves in global aviation history.
Gatwick deployed permanent counter-drone systems through 2019 and 2020 — a combination of detection radar, RF monitoring, and neutralisation capability (the exact configuration is not public for security reasons).
Heathrow accelerated its own counter-drone investment to over £5 million.
The UK government extended the drone Flight Restriction Zone around all UK airports to 5 km radius (and rectangular zones extending along runway approach paths).
Drone Acts: New legislation made it a criminal offence to fly drones near airports without authorisation, with penalties of up to 5 years in prison.
Mandatory drone registration was introduced for UK drone operators flying drones above a certain weight.
The reforms have not eliminated drone disruption — as the Heathrow events of 2019, 2025 and 2026 demonstrate — but they have substantially reduced the duration of typical drone-related closures. The December 2018 three-day shutdown remains an outlier.
The traveller lesson
The Gatwick drone event teaches the same lesson as every other disruption in this guide: when the worst happens, the systems that absorb the shock are the systems you've prepared in advance. Travellers caught in the December 2018 event spent up to three nights at the airport or in surrounding hotels. Those who had pre-booked ground transport could at least leave the airport when they decided to give up; those without spent hours queuing for taxis in winter weather.

Section 043. April 2019: The drone aftershock
Less than five months after the December event, Gatwick was briefly closed again. On the evening of 28 April 2019, an unconfirmed drone sighting near the airfield forced a temporary runway closure.
The 2019 event was very different in scale — just 75 minutes of disruption, with three flights diverted to Stansted (which subsequently returned). But the symbolic impact mattered. Gatwick had spent the months after December 2018 talking publicly about new counter-drone investments. The April 2019 incident exposed that the new measures, while reducing the likelihood of a repeat three-day shutdown, had not eliminated the possibility of brief drone-related closures.
The new normal was set: drone sightings would cause minutes-to-hours of disruption, not days. That has broadly held through 2026.
Section 054. August 2024: The cable theft and runway lighting failure
A less famous but operationally fascinating Gatwick disruption: the August 2024 runway lighting failure caused by alleged theft of high-value copper cable from airfield infrastructure.
On the morning of 25 August 2024, Gatwick reported that runway approach lighting on the eastern approach to Runway 26L was inoperative. The cause was traced to damage to a buried cable serving the lighting array. Initial investigations suggested the damage was consistent with theft — the cable contained valuable copper, and parts of it had been removed cleanly rather than damaged by accident.
The operational impact:
- Approach lighting was unavailable for the affected runway end during the period of repair.
- Flight operations continued but with reduced operational flexibility, particularly during low-visibility periods.
- Some inbound flights diverted during periods of poor visibility, and a number of cancellations cascaded through the day.
- The total disruption was concentrated over 36 hours.
The event highlighted a less-discussed vulnerability of major airports: the kilometres of buried cable that support the airfield's operational infrastructure are, at least in theory, vulnerable to theft, vandalism or deliberate sabotage. The economic value of the copper in airfield cable is significant; the operational value is much higher.
Cable theft incidents at airports, while rare, are not unprecedented. London City and Manchester have both reported attempted thefts in the past decade. The 2024 Gatwick event was the most operationally consequential.
Section 065. May 2017: BA IT outage at Gatwick
The May 2017 British Airways IT outage is best known as a Heathrow event — BA's main hub took the largest visible share of the cancellations. But Gatwick was simultaneously affected, and the Gatwick portion of the disruption has been under-reported.
At the time, British Airways operated a substantial Gatwick operation, primarily on short-haul European and leisure routes. When BA's data centre suffered the catastrophic UPS failure on the morning of Saturday 27 May 2017, both London airports were paralysed for BA operations.
Gatwick-specific impact:
- Approximately 80 BA flights cancelled on 27 May at Gatwick alone.
- Further cancellations on 28 and 29 May as the IT recovery extended.
- Tens of thousands of Gatwick BA passengers affected, on top of the larger Heathrow numbers.
- Other Gatwick airlines unaffected — EasyJet, Norwegian, TUI and others continued to operate normally, which produced the unusual scene of one airline (BA) in chaos while the rest of the airport functioned.
The Gatwick portion of the event has a useful learning point: when a disruption is airline-specific, the airport itself may still be partially functional. Passengers booked on the unaffected airlines walked through normal Gatwick operations while a few terminals away, BA passengers slept on the floor. The lesson for travellers: it's worth knowing whether your specific disruption is airline-wide or airport-wide. The response differs significantly.
Section 076. December 2010: Snow chaos at Gatwick
The December 2010 snow event affected every major UK airport. Gatwick's experience — covered briefly in the Heathrow guide — deserves a closer look here, because it tells a useful comparative story about airport operational resilience.
The same storm system that closed Heathrow for five days closed Gatwick for two. Gatwick's single runway closed on Saturday 18 December and reopened, on a limited basis, on Monday 20 December — a full day before Heathrow.
Why did Gatwick recover faster?
Newer ownership, fresh investment. Gatwick had been sold by BAA to Global Infrastructure Partners in 2009. The new ownership had invested £1 million in additional snow ploughs in the months before December 2010 — investment that would prove well-timed.
Spare capacity for recovery. Gatwick operated at around 83% slot utilisation in 2010, compared to Heathrow's 98%. When the snow cleared, Gatwick had the slot capacity to flush its backlog. Heathrow did not.
Single runway, simpler operation. With one runway to clear instead of two, Gatwick's snow-clearing operation was operationally simpler than Heathrow's, even though both airports had similar snow accumulations.
Better stand availability. Gatwick's stand layout allowed for slightly faster turnaround during the recovery phase.
The combined effect: Gatwick passengers were back in the air a day earlier than their Heathrow counterparts. For travellers caught in the storm, the difference between two days and five was the difference between a ruined weekend and a ruined Christmas.
The post-event investment programme at Gatwick (a further £8 million committed in 2011 to expand the snow plough fleet to 95 vehicles) consolidated the operational lead. Subsequent winter events have caused minor delays at Gatwick but no comparable shutdowns.
Section 087. August 2023: The NATS air traffic control failure
The August 2023 NATS flight planning system failure affected Gatwick exactly as it affected every other UK airport — fully, immediately, and beyond the airport's control.
When the NATS automated flight plan processing system failed at 08:32 on Bank Holiday Monday 28 August 2023, Gatwick had to operate under flow restrictions for the rest of the day. Departures slowed dramatically. Inbound aircraft held over France and the North Sea. Cancellations cascaded.
Gatwick-specific impact:
- Hundreds of Gatwick flights affected over 28–30 August.
- EasyJet, as Gatwick's largest carrier, took the biggest share of cancellations.
- Recovery faster than Heathrow but still measured in days rather than hours.
The lessons of the NATS event are the same at Gatwick as they are at Heathrow: when the underlying national air traffic control system fails, no airport can shield itself. The only meaningful protection is travel insurance and pre-planned ground transport.
Section 098. April 2010: The volcanic ash shutdown
Gatwick, like every other UK airport, was closed by the Eyjafjallajökull volcanic ash cloud from 15 to 21 April 2010. The event was a UK-wide and continent-wide shutdown rather than an airport-specific one.
For Gatwick specifically, the closure was particularly painful because it coincided with the peak Easter holiday travel period. Tens of thousands of leisure travellers — Gatwick's bread and butter — were stranded mid-trip. The financial impact on holiday operators (Thomson, Thomas Cook, MyTravel and others) was severe, with knock-on effects on the airport's commercial revenue for months afterwards.
The ash cloud framework adopted after April 2010 — concentration-based thresholds rather than blanket closures — has prevented any repeat at this scale, despite multiple subsequent Icelandic eruptions.
Section 109. COVID-19 and Gatwick's near-extinction event
While COVID-19 affected every airport, Gatwick was uniquely vulnerable. The airport's business model is heavily skewed toward leisure travel — exactly the segment hardest hit by lockdowns and travel restrictions.
The financial trajectory in 2020 was catastrophic:
- 80%+ year-on-year passenger decline at the peak of the lockdown.
- The North Terminal was closed entirely for much of 2020 and 2021, with all operations consolidated into the South Terminal.
- Job losses were severe — over 600 direct Gatwick Airport Limited job cuts, plus thousands across airlines, retail, hospitality and ground handling.
- The airport's owners faced refinancing pressure.
The recovery has been impressive. By 2024, Gatwick had returned to roughly 90% of its 2019 passenger volumes. Both terminals are now fully operational. New routes have been added (notably Norse Atlantic's long-haul programme). But the financial scarring of 2020–2021 took years to clear.
For travellers, the COVID era left Gatwick with a leaner operation — fewer surplus staff, less buffer in the schedule. This has made the airport marginally more vulnerable to subsequent disruption events (such as the summer 2022 staffing crunch), even as headline performance has recovered.
Section 1110. Strikes and industrial action at Gatwick
Gatwick's industrial relations history is generally less turbulent than Heathrow's, reflecting the airport's more diverse airline mix and EasyJet's pan-European workforce.
Notable strike events:
2015–2016: Gatwick check-in and ground services staff strike action, conducted by Unite union members over pay and outsourcing. Several days of disruption affecting BA, EasyJet and other carriers.
Summer 2017: EasyJet pilot dispute. Limited disruption.
Summer 2022: Wider UK airport industrial action affected Gatwick alongside other airports. EasyJet cabin crew strike action in Spain spilled over into UK operations briefly.
2024: Multiple smaller actions by ground handlers and baggage handlers, resolved through pay deals before strike days in most cases.
EasyJet's industrial relations strategy has been different from BA's. The airline operates across multiple national bases (UK, Switzerland, Portugal, Germany, Austria), so UK-only strikes are operationally less impactful than BA strikes at Heathrow. This has structurally limited the strike-related disruption at Gatwick.
Section 1211. The single runway problem — Gatwick's defining constraint
Every operational story about Gatwick eventually returns to its one-runway constraint.
The constraint is not arbitrary. Gatwick technically has two runways — Runway 08R/26L (the main runway) and Runway 08L/26R (the secondary). The problem is that they are only 198 metres apart. International standards require parallel runways to be at least 1,035 metres apart for fully independent simultaneous use. Gatwick's runways cannot be used simultaneously. The secondary runway can only operate when the main runway is closed.
This produces several operational consequences:
Vulnerability to any runway-blocking event. A burst tyre, an aircraft going off the centreline, an inbound emergency that requires extended airfield closure — at Gatwick, these affect the entire airport, not half of it. Heathrow, with two parallel runways, can run on one while the other is closed.
No redundancy during runway maintenance. Resurfacing, lighting upgrades, or repairs require operational planning that minimises closure windows. Gatwick conducts most maintenance overnight or during marginal weather periods.
Capacity ceiling is hard. With one runway and a strict cap on movements per hour, Gatwick's growth potential is constrained. The airport's owners have proposed bringing the secondary runway into full use ("Northern Runway project") — a long-running planning saga that, in mid-2026, has received initial planning approval but faces continued legal and environmental challenges.
If the Northern Runway project proceeds, Gatwick's effective capacity will increase substantially — by some estimates to 386,000 movements per year, against 281,000 today. The operational resilience benefits would be significant. The opening date remains uncertain.
Section 1312. How to survive a Gatwick disruption — the playbook
The Gatwick disruption playbook is broadly similar to the Heathrow one, with several airport-specific variations.
Specific advantages at Gatwick
Faster baseline recovery. Gatwick's spare capacity means most disruptions resolve faster than at Heathrow. Your rebooking option is more likely to be today rather than tomorrow.
More diverse airline alternatives within the airport. If your BA flight is cancelled, you may find EasyJet, Vueling or Norwegian alternatives at the same airport for some European routes. This is operationally easier than rebooking across London airports.
Better terminal experience for waiting. Gatwick's terminals have generally been rated higher than Heathrow's older terminals for passenger experience during waits. The North Terminal in particular has invested heavily in food, retail and seating capacity.
Specific challenges at Gatwick
Single-runway events are total. Any incident that blocks the runway closes the entire airport, not part of it. Heathrow's runway-specific incidents are usually partial.
Onward transport to London Heathrow is non-trivial. If your Gatwick flight is cancelled and you've been rebooked to Heathrow, the cross-airport transfer is 60–90 minutes by car or 90+ minutes by public transport (no direct rail link). Build in time.
Fewer long-haul recovery options. If your long-haul Gatwick flight is cancelled, the next available alternative may be a Heathrow flight tomorrow, not a Gatwick flight today.
The general playbook (applies to both airports)
The 14-point survival list from our Heathrow guide applies equally at Gatwick:
Get the official channel running (airline app + airport status).
Make the rebooking call immediately.
Save every receipt.
Charge your phone.
Decide: stay or move?
If your flight diverts, get ground transport sorted before landing.
Check rebooking alternatives before accepting the first offer.
Know your statutory rights.
Understand the compensation rules.
Don't sign away your rights for a voucher.
Travel insurance is not optional.
Don't book the last flight of the day.
Don't book the tightest connection.
Build redundancy into ground transport.
Section 1413. Frequently asked questions about Gatwick disruptions
How often does Gatwick close completely?
Full closures of Gatwick are rare — typically once every 5–10 years for major events. The December 2018 drone event was the most recent multi-day closure. Before that, the December 2010 snow closure was the previous comparable event. Partial disruptions affecting some flights happen multiple times per year.
What is the worst disruption in Gatwick's history?
By passenger impact, the December 2018 drone event tops the list — 140,000 passengers affected over three days. The April 2010 volcanic ash shutdown was longer (six days) but affected every UK and European airport equally, so isn't typically counted as a Gatwick-specific event.
Is Gatwick more or less reliable than Heathrow?
On most measures, Gatwick has marginally better on-time performance and slightly faster recovery from disruption than Heathrow. The main reason is Gatwick's spare capacity — operating at around 85% utilisation, the airport has room to absorb shocks that Heathrow, operating at 98%, does not.
Can I claim compensation for the 2018 drone event?
Compensation under UK261 depends on whether the cause was within the airline's control. The drone disruption was outside airline control, so fixed compensation was not owed. Care and assistance (hotel, meals, transport) were owed and most airlines provided them. Travel insurance with disruption cover may have paid out for additional losses.
What happens if my flight diverts from Gatwick to another airport?
The airline is responsible for getting you to your originally booked destination — usually by providing onward transport. Pre-booked ground transport (such as Rushxo's diversion-protected transfers) provides a reliable backup if the airline's onward transport is slow or unavailable.
Is the Gatwick second runway going to open?
Gatwick has a long-running project to bring its secondary runway into operational use, called the "Northern Runway project". As of mid-2026, the project has received initial planning approval but continues to face legal and environmental challenges. The opening date remains uncertain.
What's the best way to track Gatwick disruption in real time?
The Gatwick Airport website's status page, FlightRadar24, and airline-specific app notifications all provide real-time information. Setting up app notifications for your specific flight number is the most useful personalised information.
How can I minimise my Gatwick disruption risk?
The same general advice applies as for Heathrow: travel with carry-on only when possible, book early flights of the day, allow generous connection times, have travel insurance with disruption cover, and pre-book ground transport that adapts to diversions.
Are Gatwick's drone defences effective now?
Gatwick has invested heavily in counter-drone technology since 2018, and the duration of subsequent drone-related closures has been dramatically shorter. The April 2019, 2021 and later drone events have produced minutes-to-hours of disruption rather than days. The systems are not perfect, but the risk of a repeat three-day shutdown is significantly reduced.
Does Gatwick recover faster than Heathrow from snow?
Yes, consistently. Gatwick has more snow-clearing equipment per runway than Heathrow, and more spare capacity for recovery. The December 2010 event illustrated this: Gatwick reopened a full day before Heathrow despite both airports facing similar snowfall.
