Second NATS outage in September delays flights between the Netherlands and the UK

A technical problem at NATS' Prestwick control center on 21 September 2026 led to airspace restrictions over parts of Scotland, Northern Ireland, and northern England, delaying flights between the Netherlands and the UK. Amsterdam Airport Schiphol, Manchester Airport, Glasgow Airport, and the Belfast airports were among the locations affected, with departures held on the ground and some same-day cancellations. The disruption came less than two weeks after a broader NATS failure on 8 September, adding fresh pressure to already busy cross-border schedules. Because this was an air traffic control issue rather than an airline-caused problem, compensation is usually unlikely, but airlines should still provide rebooking or refunds, plus care such as food, drinks, and accommodation when needed.

UK air traffic control failure delays over 140 Ryanair flights, disrupting 25,000 passengers

Early on 21 September 2026, a technical failure at the UK's NATS Prestwick center in Scotland disrupted flights across Scottish and northern UK airspace, with Ryanair reporting more than 140 delayed flights and over 25,000 affected customers. Airports including Edinburgh Airport (EDI), Glasgow Airport (GLA), and Newcastle Airport (NCL) saw queues and rolling schedule changes, and airlines warned that disruption would continue even after the systems were restored. Because the root cause was an air traffic control problem outside airline control, compensation is less likely, but passengers should still receive care and assistance during long delays, plus rerouting or a refund if their flight was canceled.

Philadelphia International Airport outage delays 400 flights and cancels more than 200

A communications failure stopped flights at Philadelphia International Airport on 21 September 2026, leaving about 400 delayed flights and more than 200 cancellations by early evening. The problem spread across the Northeast, with ground stops also issued for Newark Liberty, John F. Kennedy, LaGuardia, and Boston Logan after a Verizon fiber-optic bundle was accidentally cut during construction work in New Jersey. Because the outage was outside the airline's control, compensation under EC 261 is usually unlikely, but airlines should still provide rebooking or refunds, along with care and assistance during long delays for affected passengers.

FAA telecom outage disrupts 7,000 flights at US East Coast airports

Major East Coast airports saw arrivals halted on 21 September 2026 after an FAA telecommunications failure cut off critical communications used by the Philadelphia approach control facility. The disruption hit John F. Kennedy International Airport, LaGuardia Airport, Newark Liberty International Airport, Philadelphia International Airport, and Boston Logan International Airport, and about 7,000 flights across the US were delayed or canceled during the roughly 8-hour outage, with Newark losing more than half its schedule. Because the problem affected air traffic control rather than airline operations, compensation is generally unlikely, but airlines should still help with rebooking, refunds, and care if your journey was disrupted.

Skeyes strike cancels 78 flights at Brussels South Charleroi Airport on 21–22 September

A strike at Skeyes has forced 78 flight cancellations at Brussels South Charleroi Airport across 21 and 22 September 2026, disrupting both departures and arrivals. The airport said all 32 scheduled afternoon and evening flights on Monday were canceled, with 46 more flights already cut for Tuesday’s morning and evening schedule. Because the disruption stems from air traffic control action rather than an airline issue, compensation under EC 261 is unlikely in most cases. Even so, airlines should still provide care and assistance, including rerouting or refunds for canceled flights, and AirHelp’s free flight checker can help you understand what may apply to your trip.

easyJet cabin crew in Portugal plan 2 five-day strikes at 3 airports

Cabin crew at easyJet in Portugal are due to walk out from 2–6 October 2026 and again from 19–23 December 2026, putting flights at Lisbon Airport, Porto Airport, and Faro Airport at risk. The union says about 500 flights on the Lisbon-Porto-Faro network could be canceled during the October action alone, while the December strike may disrupt even more services in the busy run-up to Christmas. Because the dispute involves the airline's own staff, passengers whose flights are canceled or delayed by more than 3 hours may be entitled to up to {{compensation_value}} compensation under EC 261.

Thunderstorms delay more than 650 flights at Denver International Airport

Severe thunderstorms over Colorado’s Front Range delayed more than 650 flights at Denver International Airport on 21 September 2026, with knock-on disruption spreading across US airline networks as aircraft and crews fell out of position. Lightning, heavy rain, and low clouds repeatedly slowed arrivals, departures, and ramp work, leaving passengers facing long waits and missed connections even after the worst of the weather started to move away. Because the disruption was weather-related and outside airline control, compensation is unlikely, but airlines should still provide care and assistance if your journey is badly affected.

Air India Express cancels 2 Patna to Delhi flights on 21 and 22 September

Air India Express has canceled flight IX1348 from Patna to Delhi on 21 and 22 September 2026, removing 2 planned flights from the schedule. The service was due to leave Jay Prakash Narayan International Airport at 7:15 am on both days, but the airline told airport officials it would not operate because of operational reasons and hasn't given a more specific explanation. Passengers have been told to check directly with the airline for alternative travel, while Patna Airport waits for further guidance. While EC 261 doesn't apply on this domestic Indian route, affected travelers may still have rights to rerouting, refunds, care, and possible compensation under applicable rules.

Gulf flight disruptions cause 1,585 delays and 40 cancellations across Riyadh, Dubai, and Doha

Travel across the Gulf was heavily disrupted on 19 September 2026, when 1,585 flights were delayed and 40 flights were canceled across major hubs including King Khalid International Airport, Dubai International Airport, and Hamad International Airport. For passengers, this meant missed connections, longer waits, and fewer rebooking options as delays spread through tightly timed operations in Riyadh, Dubai, and Doha. Because the disruption appears to have been driven by air-traffic flow restrictions, reroutings, and crew duty-time limits rather than something directly within an airline's control, cash compensation under EC 261 is unlikely in most cases, but airlines should still provide care and assistance during long delays.

Emirates, Etihad, flydubai, and Air Arabia flights hit by delays and cancellations in the UAE

Flights in the United Arab Emirates are still operating on 21 September 2026, but passengers at Dubai International Airport, Zayed International Airport, and Sharjah International Airport are seeing an uneven mix of delays, cancellations, and short-notice timetable changes. Etihad Airways and Emirates say many regional services are running, while flydubai and Air Arabia have canceled several flights to Bahrain, Kuwait, and Saudi Arabia as Gulf security tensions continue to affect operations. The United States has also warned of possible escalation in the region and says drone and missile activity could affect civil aviation. Because the disruption appears to be linked to external safety risks rather than something the airlines caused, compensation under EC 261 is unlikely, though airlines should still provide rebooking or refunds and practical care during long delays.

Japan Airlines and All Nippon Airways cancel 275 flights as Typhoon Dujuan nears Tokyo

Typhoon Dujuan has prompted Japan Airlines and All Nippon Airways to cancel 275 flights scheduled for 21 September 2026 as the storm makes a close pass of Tokyo. The cancellations include 135 Japan Airlines services, among them 15 international flights, and 140 domestic flights operated by All Nippon Airways, with routes in and out of the capital affected alongside regional services across Japan. Heavy rain and gusts of up to 144 km/h have also disrupted rail travel and left more than 4,000 households in Chiba without electricity. Because the disruption is weather-related and outside the airlines’ control, financial compensation is unlikely, but airlines should still provide care and assistance if your journey is affected.

Manchester Airport sees rolling delays on 18 September as cancellations stay limited

Flights at Manchester Airport are running behind schedule on 18 September 2026, with real-time data showing average delays of around 35 minutes and disruption levels described as elevated and rising. So far, the day is being shaped more by widespread delays than by a large number of cancellations, with both arrivals and departures affected across multiple airlines. Because the cause of individual delays hasn't been confirmed, compensation under EC 261 will depend on whether the problem was within the airline's control. Travelers should also double-check their terminal, as Manchester is now operating with a two-terminal layout.

Chicago O’Hare led global flight cancellations during mid-September storms

Chicago O’Hare International Airport recorded more cancellations than any other airport worldwide during the weather disruption that began on 14 September 2026, with the worst impact on 17 September 2026 as thunderstorms hit northern Illinois and also disrupted Chicago Midway International Airport. FAA arrival limits, ground stops, runway restrictions, and scheduled maintenance at O’Hare pushed average departure delays close to 2 hours and forced scores of preemptive cancellations. Passengers connecting through Chicago may still feel knock-on effects as airlines reposition aircraft and crews. Because the disruption was weather-related, compensation under EC 261 is unlikely, but airlines should still provide care, rebooking, or refunds where needed.

Chicago O’Hare thunderstorms push ORD to top of global flight cancellation totals in September 2026

As of 18 September 2026, Chicago O’Hare International Airport (ORD) has repeatedly topped global flight cancellation tables after thunderstorms and FAA traffic restrictions disrupted operations across Chicago. Flight trackers have shown hundreds of delays within single 24-hour periods, while construction and a federal cap of 2,708 daily movements have made it harder for the airport to recover once weather problems begin. United Airlines is the largest carrier named at ORD, but the knock-on effects can spread across the wider network because delays are often imposed before flights even depart. For passengers on EU-covered itineraries, compensation under EC 261 is usually unlikely when severe weather is the cause, though airlines still need to provide rerouting, refunds, and care during major delays or cancellations.

UAE flights on Emirates, Etihad, flydubai, and Air Arabia face delays and cancellations

Most flights from the UAE are still running, but passengers using Dubai International Airport (DXB), Zayed International Airport (AUH), and Sharjah International Airport (SHJ) on 18 September 2026 are seeing more late departures, retimed services, and some cancellations. Emirates, Etihad Airways, flydubai, and Air Arabia have all adjusted parts of their schedules as security tensions in the Gulf continue to affect regional airspace. The changes are centered on routes to Saudi Arabia, Kuwait, and Bahrain, though some Europe-bound departures have also been delayed. If your flight falls under EC 261, compensation is usually unlikely when disruption is linked to conditions outside the airlines' control, but airlines should still provide rerouting, meals, and accommodation when needed.

Frankfurt Airport disruption triggers 1,661 delays and cancellations across Europe

A fresh wave of disruption centered on Frankfurt Airport affected flights across Europe during the week of 16–18 September 2026. On 17 September 2026 alone, flights linked to Frankfurt Airport, Paris Charles de Gaulle Airport, and 10 other major hubs recorded 1,601 delays and 60 cancellations, showing how quickly problems at a major connecting airport can spread. Travelers were being advised to monitor flight status, allow extra connection time, and keep receipts if they were left waiting. If your flight was canceled or badly delayed, your rights under EC 261 will depend on the exact cause, but airlines should still provide care and assistance during the disruption.
