Passengers at London Gatwick are facing a new round of disruption today, Friday 26 June, with dozens of flights delayed or cancelled as extreme heat and thunderstorms across the UK and mainland Europe slow air traffic and stretch already busy summer schedules.

Knock-on delays build after week of wider UK disruption

Today’s disruption at Gatwick follows a difficult week for UK aviation, with industry trackers and passenger rights services reporting hundreds of delayed or cancelled flights at major airports in recent days as weather and air traffic control constraints compounded peak-season demand. Data published on Thursday highlighted significant problems at Heathrow, Gatwick, Edinburgh and Newcastle on 25 June, with poor visibility, showers and wider European congestion limiting the number of aircraft able to depart or land each hour.

That backlog has rolled into Friday, leaving aircraft and crew out of position and tightening margins on already full schedules. Publicly available airport performance reports show that Gatwick, which operates close to capacity through much of the summer, relies on quick turnarounds and high punctuality to keep services running smoothly. When those margins are eroded the impact can quickly be felt by passengers, particularly in early morning and late evening waves of departures.

Live departure boards on Friday have reflected that pressure, with a pattern of short to medium delays across a range of European leisure and city routes, alongside a smaller number of outright cancellations. The effect is particularly visible on services operated by carriers that use Gatwick as a base for dense daily rotations, where a single delayed aircraft can affect several flights in succession.

While many services continue to operate, the rolling nature of delays means some passengers are encountering longer queues at check-in, security and boarding as airlines work to consolidate loads and rebook travellers whose flights have been significantly disrupted.

Extreme heat and storms add strain to a busy summer Friday

The latest problems for Gatwick come as southern and eastern England endure record-breaking June heat combined with a growing risk of thunderstorms. Meteorologists have issued high-level heat alerts for much of the region, including London and the South East, with temperatures widely into the mid-30s Celsius and forecasts pointing to further peaks later on Friday.

Alongside the heat, forecasters are tracking bands of intense thunderstorms moving across parts of the UK, with thousands of lightning strikes reported in Scotland and northern England since the early hours of Friday. As those storm systems drift south and east, aviation analysts note that they are likely to cause further localised disruption, including temporary ground stops, diversions and holding patterns when lightning or heavy rain passes directly over airports or key air traffic sectors.

Operational updates from airlines and regional media coverage on Friday already point to weather-related disruption at Edinburgh and other northern airports, with some flights diverted or cancelled as storms cross central parts of the country. Although Gatwick has so far avoided the most severe conditions, the shared nature of European airspace means restrictions many hundreds of kilometres away can still limit the number of slots available for arrivals and departures, contributing to wider knock-on delays.

Heat itself can create additional challenges for airports and airlines, from pressure on cooling systems in terminals to performance limits for aircraft on very short runways. While Gatwick’s main runway length provides airlines with some operational headroom, staff and ground handling operations must still adapt to challenging conditions on exposed aprons and taxiways.

European air traffic control and overseas disruption ripple into Gatwick

Beyond domestic weather, Friday’s schedule at Gatwick is being affected by disturbances elsewhere in Europe, including air traffic control restrictions and storm-related issues on the continent. Travel press reports from Spain on Friday describe passengers bound for London Gatwick left on the ground in Malaga after a morning easyJet departure was cancelled when the aircraft assigned to the flight became stuck overnight at another airport because of air traffic control limits.

That type of disruption illustrates how tightly interlinked European airline networks have become. Aircraft that are unable to leave one airport due to storms, strikes or flow restrictions often miss their next rotation, and sometimes several after that, as they slowly work back into position. For a hub such as Gatwick, which handles large numbers of short-haul leisure flights to and from Mediterranean destinations, problems in one corner of the network can quickly register as gaps on the departure board.

Industry commentary on Friday has also highlighted the broader strain on Europe’s aviation system this summer, with traffic volumes exceeding last year’s levels and many airlines operating with little spare capacity. In such an environment, even modest air traffic control restrictions or weather events can have an outsized effect, leaving carriers with fewer standby aircraft and crews available to recover schedules later in the day.

Passengers flying into Gatwick from affected regions may therefore experience delays even when skies over London remain clear, as aircraft wait for revised routings or newly allocated slots to cross busy sections of European airspace.

What passengers at Gatwick are experiencing today

For travellers at Gatwick on Friday, the operational picture translates into a patchwork of experiences. Some passengers are proceeding through check-in and security with only minor delays and boarding broadly on time, particularly on early morning departures that benefited from aircraft arriving punctually the previous night. Others, especially those booked on mid-morning and afternoon services to popular holiday destinations, are facing departure boards showing delays of an hour or more or last-minute cancellations.

Terminal congestion appears to be moderate but uneven, with busier periods coinciding with the main waves of delayed departures. Social media posts and traveller reports on Friday describe longer waits at departure gates as crews and ground handlers coordinate revised turnaround times, alongside busy customer service desks as impacted passengers seek rebooking options or overnight accommodation.

General consumer guidance circulating this week continues to emphasise the importance of monitoring flight status directly with airlines and allowing extra time at the airport when high temperatures, storms or wider network issues are expected. Under UK and EU air passenger rules, travellers on cancelled flights are generally entitled to a choice of rerouting or refund, and in many cases to meals and accommodation during extended waits, even where the root cause of disruption lies outside an airline’s direct control.

With Friday marking the start of a peak summer holiday weekend, the cumulative impact of today’s delays and cancellations at Gatwick may continue to be felt into the evening and across subsequent rotations, particularly if forecast storms track closer to the London area later in the day.

Outlook for the rest of Friday and the weekend

Looking ahead to the remainder of Friday, forecasters expect very high temperatures to persist across the South East until later in the day, when cooler air and thunderstorms are predicted to move more widely across the country. Aviation analysts note that this transition period often brings short, sharp bursts of disruption as lightning, heavy showers or gusty winds force brief suspensions of ground operations or require aircraft to divert around active storm cells.

For Gatwick, which remains one of Europe’s busiest single-runway airports, the combination of residual delays from earlier in the week, today’s heat and the evolving storm risk suggests that schedules are likely to remain fragile through the evening peak. Any additional constraints, such as minor technical issues with individual aircraft or congestion on key approach routes, could therefore translate into further delays.

Beyond Friday, travel experts are watching how the wider European network absorbs the effects of both the UK heatwave and similar extreme weather episodes elsewhere on the continent. Airlines are expected to continue making short-notice adjustments to timetables, including consolidating lightly booked flights and altering aircraft allocations, as they work to protect the busiest services and rebuild punctuality.

Passengers planning to travel through Gatwick over the weekend are being encouraged by publicly available guidance to keep a close eye on airline apps and airport information screens, ensure contact details on bookings are up to date, and prepare for the possibility of schedule changes at relatively short notice as the busy summer season collides with unsettled weather patterns.
