Storms over London: what should Hungarian travelers do after Heathrow and Gatwick delays?

The storms in London on June 27 disrupted the schedules of hundreds of flights at Heathrow and Gatwick, so Hungarian travelers heading to or departing from London should plan with more time, live flight monitoring, and flexible ground programs in the coming days. The situation does not mean that every London flight is problematic, but it clearly shows how quickly peak summer traffic, heatwaves, heatwaves, thunderstorms, and air traffic restrictions can accumulate.

On Saturday, June 27, 2026, the heat in southern England turned into thunderstorms, which particularly affected the two most important London airports, Heathrow and Gatwick. According to British and international reports, more than six hundred departing or arriving flights associated with Heathrow and Gatwick were delayed during the day, with some passengers facing hours of waiting. Gatwick mentioned temporary air traffic control restrictions to the BBC, while Eurocontrol, which monitors the European network, also indicated severe delays at the two London hubs.

For Hungarian readers, this story is important because London is not only a city visit destination, but also a transfer and family visit hub. The Budapest-London Heathrow route, Budapest-London Gatwick flights, as well as departures from Vienna, are part of many Hungarian travel plans. If only a short transfer, an evening theater ticket, a prepaid transfer, or non-refundable accommodation is linked to the flight, a few hours' delay can easily reshape an entire agenda.

What happened at Heathrow and Gatwick?

The direct trigger for the recent wave of delays was the thunderstorm weather, which reached Southern England after the previous extraordinary heat. In such cases, airports and air traffic control do not slow down traffic simply for convenience. Lightning, heavy rain, sudden gusts of wind, reduced visibility and the movement of storm cells all affect how frequently aircraft can be safely launched and received.

In practice, this often does not mean a single spectacular airport shutdown, but a slowing arrival rate, gates becoming available later, shifted staff working hours, delayed arriving aircraft and rescheduled rotations. A flight departing from Budapest or Vienna may be delayed even if the weather is clear at the departure airport, because the aircraft's previous leg, its arrival in London, or the air traffic capacity of the destination airport may already be affected.

According to the Met Office's Saturday forecast, showers and thunderstorms may remain in the London and Southeast England region into the evening, while the warning for extreme heat has only gradually eased. This is significant because aviation disruptions often do not end the moment the weather improves. Aircraft, crews, and ground handling capacities must be reorganized back into the schedule.

Why does this affect Hungarian travelers?

London is simultaneously a business, family, study and tourist destination for Hungarian travelers. In addition to direct flights, many use the British capital as a transit point for onward travel to North America, Ireland or other British cities. The current situation may be particularly sensitive for those who booked their onward journey on a separate ticket, such as a low-cost flight from another London airport, or those who planned an airport transfer between Heathrow and Gatwick.

It is important to distinguish between a direct London city visit and a transfer. If someone is only arriving in London, a delay is unpleasant but generally manageable: the transfer is modified, arrival at the hotel is later, or perhaps an evening program is missed. However, if the London flight is the first element of a longer travel chain, the delay can cause a domino effect. With separately booked tickets, the second airline is typically not obliged to rebook the onward journey for free just because the first flight arrived late.

Therefore, in the coming days, it is advisable to avoid plans that rely on too short a ground transfer between Heathrow and Gatwick. Even under normal circumstances, significant travel time must be accounted for between the two airports; in stormy weather, late evening arrivals or peak times, a safe buffer is even more important. Those who check Heathrow live flight information or the Gatwick online flight board before departure will see more quickly whether their own plane is only slightly delayed or part of a wider network disruption.

What should be checked before departure?

The first step should always be the airline's own app or booking page. Airport displays and external flight trackers are useful, but the airline's message is decisive regarding boarding, gate changes, cancellations, rebookings or baggage handling information. If someone booked through a travel agency or online intermediary, it is worth finding the airline's booking reference, not just the intermediary's confirmation.

• Check the flight status at least the evening before departure and on the day of departure.
• Allow more buffer time to get to the Budapest or Vienna airport, as later flight modifications may require quick decisions.
• If transferring in London, check whether the entire route is on one ticket or consists of separate bookings.
• Save the airline's customer service and rebooking channels in advance.
• If a prepaid hotel, car rental or transfer awaits you, check the conditions for late arrival and modification.

For those arriving in London late in the evening, it may be particularly useful to think through a Plan B. If trains, buses or prepaid transfers no longer fit the modified arrival, accommodation near the airport may be more practical than starting a tired, expensive and uncertain journey to the other end of the city. In the case of Heathrow, comparing hotels around Heathrow, and for Gatwick, Gatwick airport hotels can help manage an unexpected overnight delay.

Is compensation available for weather-related delays?

Storms and air traffic restrictions are typically not the same situation as when a delay is caused by the airline's own operational error. Weather is often considered an extraordinary circumstance, so automatic monetary compensation may not necessarily be expected. However, this does not mean that the passengers have no rights.

In the case of longer delays, airlines must, depending on the circumstances, provide information, care, meal or communication assistance, and in the case of cancellation, a choice between refund and rebooking. The exact rule depends on which airline, which departure country and which legal framework is involved. For departures from Hungary or the EU, the EU passenger rights logic remains an important starting point, but for flights to or from the United Kingdom, British rules may also play a role.

The most practical advice: it is worth keeping receipts or screenshots of all costs, accommodation, meals, ground transportation and airline messages. This is not a guarantee of reimbursement, but without it, it is much harder later to prove what happened and which reasonable expenses were incurred.

Transfers, baggage and city programs: where can the plan slip?

At London airports, delays are not just about the flight. If many flights arrive delayed at once, passport control may be longer, baggage may be delayed, taxis and buses may congest, and late ground transportation options may become more expensive. Heathrow and Gatwick are both large, complex hubs; after an exhausting delay, it matters whether the passenger knows exactly which terminal they arrive at, where they collect their baggage, and which transport point they should look for.

A preliminary review of Heathrow transfer and taxi options and Gatwick airport transfers is particularly useful if traveling with family, large luggage or expecting a late evening arrival. A prepaid fixed solution is not necessarily the best in every situation, but knowledge of prices, travel times and alternatives helps to make decisions faster if the flight is delayed.

For city programs, it is advisable to make the first London day less tight. A theater, stadium tour, dinner or train journey booked immediately after the flight is riskier than a more flexible program. The lesson from the current wave of delays is not that London is a destination to be avoided, but that alongside summer weather extremes, an overly tight schedule can break expensively and frustratingly.

What does all this mean for the coming days?

Delays caused by stormy weather generally resolve gradually, but the schedules of large airports do not always return to normal immediately. If an aircraft, crew or capacity is in the wrong place late in the evening, it can have an effect on the next day. This can be particularly evident in morning flights, frequently rotating low-cost aircraft and routes where there is little buffer time between two rotations.

For Hungarian travelers, the best strategy is therefore a calm but active preparation. There is no need to automatically cancel the London trip, but it is worth checking every critical point: flight status, transfer time, separate tickets, accommodation cancellation deadlines, late transfer, travel insurance and the airline's notification channels. Those booking a London trip now should look at the total cost and flexibility, not just the cheapest fare.

Overall, the June 27 Heathrow and Gatwick delays provide a strong summer warning: flying to London remains a highly usable option, but in the peak season burdened by heatwaves and thunderstorms, buffer time is just as important a travel tool as a passport or a boarding pass.
