Thunderstorms Delay Hundreds of Flights at Heathrow and Gatwick 2026

Severe thunderstorms sweeping across southeast England have caused massive disruption at London's Heathrow and Gatwick airports, delaying hundreds of flights and leaving passengers stranded on grounded planes for hours in scorching heat. The storms followed a record-breaking heatwave with temperatures exceeding 30°C, creating chaotic travel conditions for thousands of holidaymakers and business travelers.

Massive Flight Disruptions at Major London Airports

According to flight tracker FlightAware, at least 367 flights at Heathrow and 352 flights at Gatwick were delayed on Saturday, with dozens more cancelled. Some delays stretched beyond six hours, forcing passengers to sit on tarmac without air conditioning or clear communication from airlines.

The UK's air traffic control service, Nats, warned that disruption was expected to continue throughout the day due to forecasted severe weather across the southeast. Smaller airports like Leeds Bradford, Edinburgh, and London City also experienced delays, though on a smaller scale.

Passengers Left Frustrated and Stranded

Social media erupted with complaints from frustrated travelers. One passenger reported being stuck on a grounded British Airways plane at Heathrow from 7am until noon. Another said their daughter had been sitting on an easyJet aircraft at Gatwick for four hours with no updates.

Twenty-nine-year-old Adam Joseph, stranded at Venice airport after his Gatwick-bound flight was delayed, told BBC News that passengers were not offered compensation due to air traffic control restrictions. “People are very angry … we have had no communication from British Airways whatsoever,” he said, adding that he gave up his chair to a pregnant mother.

Airlines Respond to the Crisis

British Airways issued a statement acknowledging the disruptions, saying: “Like other airlines, we’ve had to make some adjustments to our schedule today due to air traffic control restrictions caused by adverse weather conditions.” They apologized for the inconvenience and said teams were working to help affected customers.

EasyJet took a proactive approach by pre-emptively cancelling some flights to and from Gatwick. A spokesperson said: “We are doing all possible to minimise the impact … notifying passengers in advance with their options to rebook or receive a refund as well as hotel accommodation and meals where required.”

Impact on Travelers and Compensation

Under UK and EU regulations, passengers are typically entitled to compensation for delays over three hours, but extraordinary circumstances like severe weather can exempt airlines from paying. This leaves many travelers without financial recourse, despite significant inconvenience.

Key facts about the disruption:

• 600+ flights delayed or cancelled across Heathrow and Gatwick
• Some delays exceeded 6 hours
• Smaller airports like Leeds Bradford and Edinburgh also affected
• Passengers stranded abroad in Venice and other European cities

What Passengers Should Do

If your flight is delayed or cancelled, check your airline's policy for rebooking and refunds. Keep all boarding passes and receipts for expenses like meals and hotels. Contact your travel insurance provider to see if weather-related disruption is covered.

For real-time updates, monitor FlightAware or your airline's app. Passengers stuck on the tarmac should request cabin crew to provide water and updates every 30 minutes under aviation guidelines.
