Why Did UK Airports Ground Flights?
What Happened?
Around 2:39 p.m. GMT, NATS experienced a radar-related failure that led to a precautionary restriction on aircraft movements in the London Control Area, covering most of England and Wales. Although the disruption lasted only about 20 minutes, the clearance delay triggered the grounding of all outbound flights and forced some inbound planes to hold or divert.
Grounding and Resumption
After the system was restored by around 4:30 pm, operations resumed gradually. However, thousands of passengers remained affected, with airport staff managing extensive cancellations, delays, and flight diversions. Heathrow, the busiest UK airport, saw flights resume within the hour but airlines warned disruption could last several more hours.
Airline and Government Response
British Airways reported operating at just two-thirds of its usual flight capacity at Heathrow until around 7:15 pm, after which it expected to return to normal operations.
The UK Transport Secretary, Heidi Alexander, confirmed the technical issue was resolved but cautioned that travel disruption could continue, advising travelers to check with their airlines for updates.
Passenger Impact
Travel analytics firm Cirium estimated that at least 45 departures and 35 arrivals were canceled nationwide, and flights were either delayed or diverted to alternative airports. Some long-haul journeys were rerouted mid-air, and passengers reported being held on the tarmac for extended periods without clear updates.
Calls for Accountability
Ryanair demanded the resignation of NATS CEO Martin Rolfe, calling the incident 'outrageous' and highlighting a failure to learn lessons from a similar outage in 2023 that affected around 700,000 travelers.
Meanwhile, the Liberal Democrats, led by Sir Ed Davey, called for an independent investigation to assess the resilience and reliability of UK air traffic control systems.
This incident serves as a stark reminder of how dependent modern aviation is on digital infrastructure, and raises urgent questions about the reliability of NATS systems—especially given past failures during peak travel periods.

Heathrow chaos as passengers abandon cars to walk to packed terminals
Passengers complained of chaotic scenes at London's Heathrow Airport today after the unscheduled closure of a nearby road tunnel caused major disruption. Terminal buildings were crammed with unhappy passengers, many of whom shared images of lengthy queues on social media. Nearby roads, including motorways, were gridlocked, with some travellers attempting to reach the airport forced to abandon their transport and walk with their luggage as traffic backed up. In a statement, Heathrow said there had been a 'technical issue' which had caused the closure of the road tunnel leading to terminals 2 and 3. Announcing the tunnel had reopened, the airport said there was 'still congestion' and added 'we recommend allowing extra time for your journey. We apologise for any inconvenience caused.' Passenger Jane Boyd criticised Heathrow for failing to be prepared for such emergency situations. She shared an image of passengers crammed inside one of the terminals and described the situation as an 'absolute mess', adding that there were no staff to 'direct lines of confused passengers'. Sheila Carney Bowen sent a message to Aer Lingus saying there was 'utter chaos' at Heathrow, with the airline's priority queue 'swamped' with non members. Another passenger who shared an image of a packed airport walkway said: 'What a mess at Heathrow. Problems with the tunnel going to terminal three so traffic was backed up as everyone had to go around to other terminals and take the subway to three. Very little communication as to where to go.' Malcolm Cowling wrote that the UK's major international hub airport appeared to be competing for the 'Mickey Mouse Airport of the Year Award'. 'Who in their right mind would fly from here unless you had to?' he said. Today's problem is the latest to frustrate passengers. Last week, a 'radar-related issue' caused an air traffic control (ATC) failure that grounded flights across the UK. In March, the airport was closed for almost 24 hours after a fire in a nearby electricity substation caused a massive power cut, which cost the airport millions of pounds. More than 270,000 air passenger journeys were disrupted by the incident. Last week, Indian-born businessman Surinder Arora set out his plans to go up against Heathrow in the battle to develop a third runway and new terminals at the UK's main hub. His £25 billion plan could go head to head with Heathrow's own grander £33 billion scheme to develop a longer runway that passes under the M25 motorway.

Storm Floris causes power cuts, travel disruption in UK
Powerful winds of over 100mph from Storm Floris have caused significant travel disruption, power outages, and the widespread cancellation of events across much of the UK. Central and northern Scotland bore the brunt of the severe weather on Monday, facing conditions more typical of a turbulent winter's day. According to the Met Office, a peak gust of 134mph was recorded at the summit of Cairn Gorm in the Highlands, standing 1,245 metres above sea level. The strongest lowland gust—away from mountainous terrain—reached 80mph at South Uist in the Outer Hebrides. Follow Emirates 24|7 on Google News.

Emirates sees first-class rise in premium flights to UK
Emirates airline has recorded a surge in premium bookings by visitors to the UK, which it claimed is 'driving forward economic growth' in Britain. Bookings for first-class seats on flights from China and India during the first half of the year were up 27 per cent and 17 per cent respectively, compared with the same period in 2024, the airline said. For travel from Australia, the increase in business-class bookings was 10 per cent. Emirates said regional UK airports such as Glasgow and Newcastle are also expected to announce an increasing number of Chinese visitors, with inbound passenger numbers anticipated to rise by 18 per cent and 45 per cent respectively in the second half of 2025 compared with a year earlier. All Emirates journeys on these routes involve changing planes in Dubai. The airline recently signed a declaration of intent with VisitBritain to boost inbound tourism. Emirates UK divisional vice president Jabr Al Azeeby said: 'The UK is one of the most important markets in Emirates' global network and the growth in bookings we've seen over the past year reflects that. 'We've seen a noticeable increase in inbound arrivals from key destinations such as Australia, India and China, driving forward economic growth here in the UK. Our partnership with VisitBritain underscores our commitment to grow tourism for the UK from key strategic markets.' The British government is aiming to attract 50 million international visitors a year by 2030. An estimated 41.2 million inbound visits were made last year. VisitBritain chief executive Patricia Yates said: 'Expanding airline routes and seat capacity into our regional gateways is crucial to our competitive tourism offer. 'International visitors are forecast to spend more than £34 billion in the UK this year. Making it easier for visitors to explore our nations and regions boosts that spending across more of Britain, supporting jobs, businesses and driving growth for local economies.'
