Key Takeaways
• Paris-Orly Airport canceled over 130 flights after a May 18, 2025 radar failure forced a 40% flight reduction.
• Outbound flights to major French, European, North African, and U.S. destinations were especially hard-hit by immediate cancellations and delays.
• DGAC is restoring radar urgently but offers no timeline; travelers should check with airlines for updates and rebooking options.
Travelers at Paris-Orly Airport today face one of the most severe disruptions in recent memory. On May 18, 2025, a major radar failure struck the airport’s air traffic control tower, forcing the French Civil Aviation Authority (DGAC) to order airlines to cut their flight schedules by 40%. This reduction stands out as one of the largest single-day cuts in the airport’s history, bringing confusion and distress to passengers, airlines, and staff alike.
Immediate Crisis at France’s Second-Busiest Airport

Paris-Orly Airport, handling over 33 million passengers last year, suddenly slowed down as a technical problem wiped out vital radar systems in the control tower. More than 130 flights were canceled within hours. Most affected were outbound flights. Major airlines such as Air France, Transavia, and Vueling had to quickly ground planes. This left hundreds of passengers lining up for answers, with many unable to travel to or from Paris.
Travelers quickly felt the impact as loudspeaker messages announced cancellations and delays. For those already in the airport’s terminals, rows of people checked their phones and scanned departure boards, hoping for good news. According to the DGAC, the breakdown was so severe that only a sharp cut in flights could keep the skies above Paris safe.
Which Flights and Destinations Are Affected?
The radar failure at Paris-Orly has caused a chain reaction, affecting destinations both near and far. It has led to canceled flights not just within France but all across Europe and further.
Here are the key areas seeing the most disruption:
– Major French cities: Domestic flights between Paris-Orly and cities like Toulouse have been cut. These routes are vital for business and family travel within France.
– European cities: Many flights to and from countries like Spain, Denmark, Italy, Germany, Austria, the Netherlands, and Ireland have been canceled. Popular places such as Palma de Mallorca and Alicante were among those hit.
– North Africa and Middle East: Travelers hoping to fly to places like Tunis (Tunisia), Rabat (Morocco), and Saudi Arabia had to find other plans or wait for updates.
– United States: Even those heading to the United States saw their plans upended.
The impact was twofold. Some travelers trying to leave Paris were forced to stay, while many others trying to land at Paris-Orly had last-minute changes or diversions. Airplanes meant to depart stayed on the tarmac, while passengers arriving faced uncertainty and backup plans.
How Large Is the Disruption?
To understand how big this problem is, consider that Paris-Orly usually sees hundreds of flights each day. By cutting 40% of scheduled flights, more than 130 departures and arrivals stopped as of the afternoon.
Paris-Orly is only second to Paris-Charles de Gaulle Airport in France for passenger numbers. The two together serve as the main international gateways for the country. When one faces a problem on this scale, the ripple effects travel far and wide.
Travelers had to deal with delays, missed connections, and uncertainty about their holiday, business meetings, or even family visits. As reported by VisaVerge.com, those with connecting flights at other European or American cities faced challenges, as rebooking was tricky with so many cancellations at once. The airport soon filled with stranded families, business travelers, and tourists, each with their own urgent stories.
DGAC’s Response: Working to Restore Order
The DGAC was quick to issue a statement about the radar failure, but it did not share much about what caused the breakdown. Instead, its main message was that “technical teams are fully mobilized to restore normal operations as soon as possible.” This means they have brought in extra staff and experts to fix the radar at the control tower. At this time, they have not set a timeline for full recovery or confirmed whether the disruption will stretch into Monday, May 19.
The DGAC included the word “regulation” in their updates. In this context, “regulation” means strict control or limits on the number of flights allowed to depart or arrive, all to make sure that the reduced radar ability does not cause an unsafe situation in the air. This kind of regulation is rare but sometimes necessary when the core systems break down.
Because of the large number of affected flights, the DGAC advised all travelers flying into or out of Paris-Orly to check with their airlines—either by phone, online, or at the airport—for the latest about their flights. Airlines also scrambled to send messages and emails to their customers, but the sheer number of travelers made this a challenge.
Why Does a Radar Failure Have Such a Big Impact?
The air traffic control (ATC) radar is the heart of an airport’s ability to manage airplanes in and around its airspace. ATC uses radar to “see” where every plane is in real-time, even when bad weather, clouds, or darkness blocks the pilot’s view. When the radar fails, controllers have to work with backup tools, which greatly limit the number of planes allowed in the sky safely.
A 40% cut in flights means hundreds of people—maybe thousands—left waiting for updates or stuck in hotels. Some people may be able to take other flights from the much larger Paris-Charles de Gaulle Airport, but not all routes can be moved so quickly. For many, it means waiting until technical teams fix the radar and flights return to a normal schedule. The last time Paris-Orly had a system-wide emergency like this was several years ago, and it did not reach this level of disruption.
Airlines Take Emergency Steps
Air France, Transavia, and Vueling, which operate many daily flights from Paris-Orly, acted fast when the DGAC said they must sharply reduce operations. They grounded some planes at the airport and redirected others before they left their home airports. These quick steps were needed but left many travelers with little warning about their canceled flights.
For some, the first sign of trouble was a message from their airline or a delay notification on their phone. Many only learned about the problem when they got to the airport and saw packed halls and long lines at check-in counters. Airline staff had to explain to frustrated passengers that no more tickets could be issued for the day and that refunds or rebooking could take time.
What This Means for Passengers: Next Steps
If you have a flight booked at Paris-Orly today or tomorrow, checking with your airline is the most important step. Because the radar failure affects both arrivals and departures, there is a chance your flight might be delayed, canceled, or redirected to another airport, especially Paris-Charles de Gaulle.
Airlines are encouraging travelers not to come to the airport unless they have clear confirmation that their flight will still operate. For up-to-date information, you can use official online resources. The French Civil Aviation Authority offers alerts and information for travelers at this official government page.
If you do need to rebook, keep the following in mind:
- Airline customer service lines and airport help desks are likely to be very busy.
- Some flights may be rebooked for several days later, depending on when the radar is fixed.
- Passengers might be eligible for compensation or refunds, but this will depend on airline rules.
Be sure to have your booking number and identification ready if you need to talk to airline staff or request a refund.
Short and Long-Term Impacts
The most pressing result of the Paris-Orly radar failure is the disruption to tens of thousands of travelers’ plans. Some, including families on vacation or business groups, may face extra costs for hotels, food, or missed meetings.
For airlines, the radar failure means losses as canceled flights reduce ticket sales, and more staff hours go into handling the emergency. Airport workers also have to handle larger crowds as people wait for information about next steps.
In the longer term, this event is likely to renew discussions about how airports can prevent such wide breakdowns in the future. Questions will be raised about regular radar maintenance, backup systems, and how quickly airports can recover from similar crises.
Paris-Orly’s status as a major travel hub—serving half as many passengers as Paris-Charles de Gaulle—means today’s issues could have a ripple effect across many parts of Europe and beyond. At the moment, the main priority is safety, followed by getting service back to normal as soon as technical teams allow.
Diverse Reactions and Viewpoints
Today’s events have stirred strong feelings. Stranded travelers voiced frustration but also some understanding. “We can’t blame anyone for putting safety first,” said one airline worker. Some industry experts, however, have called for more rapid use of backup systems to prevent such large-scale reductions. Others believe the DGAC made the right decision because safety must always come first when it comes to air travel.
It is clear there will be reviews and reports once operations return to normal at Paris-Orly Airport. The public will want answers about what caused the radar failure, what was done to solve it, and what changes will be made to avoid it happening again.
What to Watch For: Will the Issue Continue?
With scores of flights already canceled and a 40% reduction in schedules, attention now turns to how quickly Paris-Orly can get back to full operations. The DGAC has not said if problems will last beyond today, May 18. Travelers with flights on Monday, May 19, and beyond are urged to check often for updates. The French Civil Aviation Authority or your airline remains the best source for the latest details.
