Gatwick strike next week could bring fresh delays for flyers

Airline passengers using London Gatwick next week are being urged to prepare for possible disruption as more than 220 assisted-travel workers plan a series of September strikes at the UK’s second-busiest airport.

Nine strike days planned across late September

Published coverage indicates that assisted-travel staff employed by contractor Wilson James intend to walk out for nine days this month, with action set to begin on Thursday 17 September and continue through Monday 21 September, before resuming from Wednesday 23 September to Saturday 26 September 2026. The industrial action follows a dispute over pay between members of the Unite union and the company, which provides special assistance services for passengers at Gatwick.

According to information compiled by strike-tracking sites and union updates, the planned walkouts come after workers reportedly rejected a two-year pay offer that included a 3.4 per cent rise and a one-off bonus for 2026, followed by a further increase linked to inflation in 2027. Unite has argued in public statements that the proposal fails to keep pace with rising living costs for staff delivering front-line services at the airport.

The strike dates fall within a period that is already busy for leisure and late-summer business travel, raising concerns that any disruption could have a wider impact on passengers connecting through Gatwick. The airport handled tens of millions of travelers annually before the pandemic and remains a major gateway for European short-haul and long-haul services.

Wilson James provides Gatwick’s assisted-travel operation, which supports passengers with reduced mobility from arrival at the terminal through to boarding and onward connections. Any sustained staffing shortage in this area could create bottlenecks in parts of the journey that depend on dedicated personnel, such as boarding, disembarkation and transfers within the terminal.

Which passengers are most likely to be affected

Reports on the dispute explain that the staff involved are primarily responsible for supporting passengers who require extra help at the airport, including those using wheelchairs, mobility aids or meet-and-assist services. Disruption to these teams may not necessarily result in large numbers of flight cancellations, but it could lead to longer waits for boarding, assistance vehicles and staff escorts.

Travel-industry briefings note that Gatwick has said it aims to maintain its flight schedule during the strikes, working with Wilson James and other partners to reduce the impact on operations. However, publicly available information also points out that passengers needing special assistance are often closely dependent on guaranteed timings, so even modest delays can have outsized consequences for missed connections or extended time in the terminal.

Indirect effects are also possible for other travelers if boarding takes longer than usual or if ground operations must be adjusted to prioritise passengers requiring assistance. For example, slower disembarkation on arriving services can knock on to turnaround times, potentially affecting departure punctuality across some flights during peak periods.

Past industrial action involving airport support staff in the UK has shown that disruption can be uneven across the travel day. Some flights may leave on time, while others encounter significant setbacks depending on staffing levels, passenger volumes and how many travelers have pre-booked assistance for a given departure window.

How the pay dispute at Gatwick unfolded

Background material on the dispute indicates that the current row follows a period of wider industrial tension across the UK aviation and transport sectors, where unions have sought to recoup pay and conditions they say were eroded during and after the pandemic. Wilson James workers at Gatwick, who are not directly employed by the airport itself, argue that their pay has not kept pace with responsibilities that include lifting, escorting and coordinating support for thousands of passengers each day.

A recent Unite briefing on the strike states that members unanimously rejected the company’s pay proposal, citing concerns about real-terms wage erosion. Union documentation sets out that the offer included a multi-year deal combining a percentage uplift with a small non-consolidated payment, which would not permanently increase base salaries. Workers also raised issues around pensions and differentials with staff performing similar roles at other major airports.

Specialist aviation publications have highlighted that Gatwick, like other large hubs, relies heavily on outsourced providers for key passenger services. That model can complicate negotiations when pay disputes arise, because responsibility is shared between the contractor, the airport operator and airlines that ultimately depend on smooth passenger flows.

The timing of the action, spread across two separate blocks of strike days, has been interpreted by industry commentators as designed to maximise leverage while allowing for further talks if either side signals a willingness to revise their position. At the time of writing, no updated offer has been made public, and the strike dates remain on official calendars.

Advice for travellers with flights via Gatwick

Travel analysts recommend that passengers due to fly through Gatwick during the affected dates build extra time into their journeys and pay close attention to airline and airport updates. Those who have booked assisted-travel services are being advised to reconfirm their needs in advance, arrive earlier than usual and contact their airline promptly if they experience long waits for support on the day.

Guidance published on travel advisory sites suggests that passengers who can manage with carry-on luggage only may find it easier to move through the terminal if queues develop. However, travellers with mobility or medical requirements are encouraged not to change established assistance plans without consulting their airline or service provider first, as doing so could introduce new complications.

Several aviation commentators note that airlines are still recovering from recent air traffic control problems that caused widespread disruption at UK airports earlier this week. While the issues are unrelated, the combination of residual delays and the prospect of strike action at Gatwick has prompted warnings that schedule resilience could be further tested if additional disruptions arise.

Passengers are urged to monitor their airline’s app or website on the day of travel, as changes to gate assignments, boarding times or flight schedules may be communicated at relatively short notice. Standard passenger rights under UK and EU regulations continue to apply where flights are significantly delayed or cancelled, though industrial action involving third-party staff can affect how compensation rules are interpreted in specific cases.

What this means for late-summer air travel

The planned Gatwick strike underscores the continuing fragility of UK air travel as the industry enters the tail end of the busy summer season. Demand has remained strong through early September, with many travellers taking advantage of shoulder-season fares, while airports and airlines continue to manage staffing constraints and operational pressures.

Industry data shows that even targeted industrial action can create ripple effects across airline networks, particularly at major hubs where aircraft and crew operate multiple rotations per day. Gatwick’s role as a base for low-cost and leisure carriers means that any extended delays could quickly spread through short-haul schedules to popular holiday destinations.

Observers also point out that this latest dispute fits into a broader pattern of strike activity across UK transport, health and public services in recent years, driven largely by rising living costs and disputes over working conditions. For air travellers, that has translated into a more unpredictable operating environment, where last-minute changes, longer queues and tighter schedules have become more common.

With nine days of industrial action currently scheduled at Gatwick between 17 and 26 September, passengers planning to travel through the airport during that period are likely to face at least some level of disruption risk, even if flights operate broadly as planned. How severe the impact will be depends on whether the parties reach a compromise in the coming days or whether the strike goes ahead in full.
