FAA Ground Stop Causes Widespread Flight Disruptions
Canadian travellers continue to face delays and cancellations after the United States Federal Aviation Administration (FAA) lifted a historic four-hour nationwide ground stop on Friday evening. The disruption, which affected air traffic to, from, and through the U.S., is still causing lingering issues for passengers and airlines this weekend.
Timeline and Cause of FAA Ground Stop
The FAA imposed the ground stop at 3:54 p.m. ET on Friday due to telecommunications and data-overload issues, halting all domestic departures and severely disrupting air traffic. The stoppage was lifted at 8:15 p.m. ET, but officials warned that full flight schedules would take time to recover.
Sean Duffy, U.S. Transportation Secretary, explained in a press conference that the air traffic control system became overloaded with data, leading to unstable radar and communication issues. The FAA assured the public that all flights were accounted for and that the issue was not connected to cyberattacks or the Microsoft 365 outage that occurred the previous day.
Impact on Canadian Travellers
Although the disruption was centered in the U.S., Canadian travellers flying to, from, or through the country have experienced numerous cancellations and delays. Air Canada, WestJet, and Porter Airlines have all issued travel advisories urging passengers to check their flight status before going to the airport, as service interruptions may continue throughout the weekend.
On Friday, Air Canada cancelled many flights to and from the U.S. for the evening and warned that flights destined for the Caribbean and South America with stopovers in the U.S. might also be affected. Passengers whose flights were cancelled are advised to check their bookings and use online self-service tools for rebooking or managing their travel.
WestJet is permitting eligible travellers with flights between November 13 and 15 to make a one-time change or cancellation without fees for U.S., Mexico, and Caribbean destinations. Porter Airlines expects it will take the entire weekend to stabilize its schedules and offers complimentary rebooking options when space is available. Customers are being told to anticipate longer wait times when contacting the airline.
Toronto Pearson Airport’s Response
Toronto Pearson Airport, a major Canadian travel hub, has bolstered terminal staffing and expanded its Passenger Care Team on Saturday to assist travellers facing ongoing delays and confusion. Airport officials encourage passengers to remain informed about their flight status and to seek assistance from onsite staff if needed.
Historic Scope and Recovery Efforts
This FAA ground stop is only the second national halt of its kind in U.S. history, the first occurring after the September 11, 2001 attacks. The FAA says its systems have now been thoroughly tested and air operations are resuming across the country, but the effects are expected to linger as airlines and airports work to restore operations.
Canada’s Minister of Transport, Steven MacKinnon, shared that Canada offered support to U.S. officials and remains prepared to provide further assistance for accommodating U.S.-bound aircraft or other needs as required.
Travellers are urged to check airline and airport websites for the latest updates and exercise patience while the aviation industry recovers from this major service interruption.
