What Changed
On 2026-06-27, thunderstorms across the UK caused widespread delays to flights at Heathrow and Gatwick, two of the country’s busiest international airports. The disruption affected hundreds of services, with international travellers facing late departures, delayed arrivals, missed connections and longer waits in terminals. Weather-related air traffic restrictions can reduce the number of aircraft allowed to take off or land safely, which often creates knock-on delays even after storms pass. Passengers were warned that disruption could continue into Sunday as airlines, airports and air traffic controllers worked through backlogs and aircraft positioning issues.
Who It Affects
International travellers flying through Heathrow or Gatwick, including UK holidaymakers heading overseas, inbound visitors arriving in London, passengers with long-haul connections, families travelling at the start of summer trips, and anyone booked on tight onward rail, coach, cruise or domestic flight connections.
Hundreds of Heathrow and Gatwick flights were delayed after thunderstorms hit the UK, with knock-on disruption possible into Sunday.
Hundreds of flights at Heathrow and Gatwick were delayed on 2026-06-27 after thunderstorms hit the UK, creating a difficult day for international travellers using London’s two busiest airports. The disruption affected departures and arrivals, with delays likely to ripple through airline schedules because aircraft, crews and passengers can all end up out of position after severe weather. Travellers were warned that delays could continue into Sunday, particularly where late aircraft arrivals, missed crew duty windows or air traffic restrictions created a backlog. Anyone flying through either airport should check live flight information before setting off and prepare for longer waits than normal.
What Happened at Heathrow and Gatwick
Thunderstorms across the UK on 2026-06-27 led to widespread disruption at Heathrow and Gatwick, with hundreds of flights delayed across the two airports. During thunderstorm activity, airports and air traffic control may need to slow the rate of arrivals and departures to maintain safe spacing between aircraft and avoid areas of hazardous weather. Even if a storm passes quickly, the effect can last much longer because delayed inbound aircraft cannot operate their next outbound services on time. This is why passengers can still face disruption after conditions on the ground appear to have improved.
Why Weather Delays Create Knock-On Problems
Airline schedules are tightly connected, especially at major hubs such as Heathrow and Gatwick, where aircraft may operate several flights in one day. A weather delay on an inbound European or long-haul service can delay the same aircraft’s next departure, which may then affect later rotations. Crew working-hour limits can also become an issue if a delay pushes pilots or cabin crew beyond their permitted duty time. In more severe cases, airlines may need to find replacement crew, change aircraft, hold passengers on the ground or cancel a later service to protect the rest of the schedule.
Who Should Be Most Concerned
The highest-risk travellers are those with tight onward connections, especially if the second journey is booked separately from the first. Long-haul passengers connecting through Heathrow, holidaymakers flying from Gatwick, families with checked luggage, cruise passengers and travellers heading to time-sensitive events should all allow extra flexibility. Inbound visitors arriving into London may also face late-night transport problems if their flight lands after rail or coach services have reduced. Passengers with mobility assistance, young children or essential medical needs should contact their airline or airport assistance provider early if delays become prolonged.
Practical Tips
Tip 1: Check your flight status directly with your airline before leaving for Heathrow or Gatwick, as airport departure boards may lag behind airline operational updates during fast-moving weather disruption.
Tip 2: If your flight is delayed, keep receipts for reasonable food, drink and essential expenses, but remember that cash compensation is usually not payable when delays are caused by severe weather beyond the airline’s control.
Tip 3: Build extra time into onward plans, especially if you are connecting to a separate ticket, a cruise departure, a train from London or a hotel check-in with a strict arrival window.
Tip 4: Stay close to official channels: use your airline app, Heathrow or Gatwick live flight pages, and gate screens rather than relying on social media posts or third-party flight trackers alone.
Mistakes to Avoid
✕Mistake 1: Assuming a delay will stay short; thunderstorm disruption can worsen quickly if air traffic flow restrictions, aircraft rotations or crew hours are affected.
✕Mistake 2: Going to the airport without checking your airline’s latest instruction, as some passengers may be told to arrive later while others still need to check in on time.
✕Mistake 3: Booking a replacement flight before your airline confirms your options, because you may lose refund, rebooking or duty-of-care support if you abandon the original booking too early.
✕Mistake 4: Expecting automatic compensation for a weather delay; under UK and EU passenger rights rules, airlines must usually provide care for long waits, but severe weather is generally classed as an extraordinary circumstance.
Quick Checklist
Check your airline app and airport live flight status before travelling
Confirm whether check-in, bag drop and boarding times have changed
Save receipts for meals, drinks and essential delay-related costs
Verify onward connections, hotel arrival times and transfer bookings
Have a backup plan for missed connections or late-night arrivals
Before travelling to Heathrow or Gatwick, check your flight status in three places: your airline app, your airline’s website and the airport’s live departure or arrival page. If the airline says to arrive as normal, follow that advice, because check-in and bag-drop deadlines may still apply even when a flight is delayed. If the airline advises passengers to arrive later, take a screenshot or save the message in case there is confusion at the airport. Avoid relying only on third-party flight-tracking apps, which can be useful but may not include the airline’s passenger instructions.
Your Rights During Weather Disruption
For flights departing the UK, passenger rights rules usually require airlines to provide care during long delays, including meals, refreshments and, where necessary, accommodation and transport between the airport and hotel. However, cash compensation is generally not due when the disruption is caused by severe weather, because thunderstorms are normally treated as an extraordinary circumstance outside the airline’s control. That distinction matters: you may still be entitled to assistance even if you are not entitled to compensation. Keep receipts for reasonable expenses and submit them to the airline after travel if support was not provided at the airport.
Handling Missed Connections
If your connecting flights are on one booking, the airline should normally rebook you if the weather delay causes you to miss the next leg. Go to the airline’s transfer desk, service desk or app-based support channel and ask for the next available routing to your final destination. If your onward flight, train, coach or cruise was booked separately, protection is much weaker, and you may need to claim through travel insurance rather than the airline. This is why travellers on separate tickets should contact the onward provider as soon as the first flight is delayed.
Airport Survival Tips During Long Delays
Keep essentials with you in cabin baggage, including medication, chargers, baby supplies, travel documents, a change of clothes and any items you would need if your checked bag is delayed. If you are waiting in the terminal, stay near official information screens and listen for gate changes, because delayed flights can move quickly once a new departure slot is assigned. Use airline apps for rebooking where possible, as phone lines and service desks can become overwhelmed during weather disruption. If travelling as a family or group, designate one person to monitor updates while others handle food, assistance needs or onward travel arrangements.
Planning for Sunday Knock-On Delays
Because disruption was warned to continue into Sunday, passengers booked after the storms should not assume their flight is unaffected. Aircraft may still be arriving late from previous sectors, and some crews may need to be repositioned before normal schedules resume. If you have flexibility, check whether your airline is offering free rebooking or travel waivers, although these are not guaranteed for every weather event. Travellers with important commitments should consider earlier airport transfers, refundable backup accommodation or flexible onward transport until the schedule stabilises.
Bottom Line for Travellers
The practical priority is to verify your flight directly with your airline, arrive according to official instructions and keep your onward plans flexible. Heathrow and Gatwick can recover quickly from short weather events, but thunderstorms often create air traffic restrictions that produce delays long after the worst weather has moved on. Passengers should prepare for queues, late gate changes and possible missed connections, especially on international itineraries. Keep receipts, document airline messages and avoid making expensive alternative arrangements until you know what your airline will provide.
Tip 5: Have a backup route ready, such as a later train, flexible hotel booking or alternative onward flight, because weather delays can trigger missed connections even when the first delay looks minor.
