What is happening: the “ATC Zero” event
On September 21, 2026, starting at 19:27 UTC, a serious technological malfunction caused the total suspension of air traffic control (ATC) operations at the main airports on the East Coast of the United States. This event, defined as “ATC Zero,” led to the temporary closure of Boston Logan International Airport (BOS), Newark Liberty International Airport (EWR), John F. Kennedy International Airport (JFK), LaGuardia Airport (LGA) and Philadelphia International Airport (PHL).
The term “ATC Zero” indicates that essential facilities and equipment for air traffic control are out of service, making it impossible to safely manage incoming and outgoing flights. The malfunction affects critical instruments such as radar, communication systems, and management software.
Airports and flights at risk
Since the entire control chain is compromised, all arriving and departing flights from these airports have been suspended until further notice. This includes both domestic and international flights.
If your itinerary includes one or more stops at BOS, EWR, JFK, LGA, or PHL, it is highly likely that your flight will be canceled or significantly delayed. Airlines will soon begin reorganizing the situation, but wait times may be long.
Passenger rights under EU261 regulations
This event takes place in the United States, so EU261 regulations do not directly apply unless the flight is part of a journey originating in the European Union or operated by a European airline (e.g., Ryanair or easyJet).
In cases where a flight departing from the EU is affected by delays or cancellations due to this event in the USA, European regulations protect passengers with compensation, assistance, and rights to reimbursement or alternative flights. However, in the United States, passenger rights vary depending on individual airline policies and FAA regulations, which do not impose compensation obligations similar to EU261 in cases of issues caused by ATC.
In any case, it is recommended to always consult your airline and travel insurance for any specific coverage.
Practical advice for travelers
- Check your flight status: before heading to the airport, visit the airline’s website and use flight tracking services.
- Be prepared: in case of potential delays, bring snacks, water, and entertainment devices.
- Explore alternative flight options: consider advancing or postponing your trip if possible. You might look for alternative, less congested airports in the area, such as Boston Logan (BOS) versus other airports in New England.
- Keep your documents and contact information handy: save assistance numbers and emails to communicate with your airline.
- At the airport: go to assistance counters for information and to request rebooking or refunds.
Conclusion
The ATC Zero event represents a serious and unexpected disruption beyond the control of passengers and airlines, but being prepared and knowing your rights and options can help you get through this type of disruption with as little stress as possible.
