This follows a dramatic four-hour nationwide ground stop in the U.S. that brought transatlantic travel to a standstill on Friday evening. While the <strong>FAA<\/strong> lifted the order at approximately 8:15 PM ET on Friday, officials warn that returning to normal operations will be a slow process due to aircraft and crews being significantly out of position.<\/p>\n<p>The disruption has caused a massive backlog at major UK hubs including <strong>London Heathrow<\/strong> and <strong>Manchester Airport<\/strong>. British Airways and Virgin Atlantic have reported multiple cancellations and &quot;slight delays&quot; for Saturday departures. Aviation tracking data from <em>FlightAware<\/em> indicates that more than <strong>11,000 U.S. flights<\/strong> were delayed or canceled during the peak of the crisis, with the total number of affected flights surpassing <strong>15,000<\/strong> by Saturday morning.<\/p>\n<p>U.S. Transportation Secretary <strong>Sean Duffy<\/strong> and Homeland Security Secretary <strong>Markwayne Mullin<\/strong> clarified in a White House briefing that the outage was &quot;mechanically driven&quot; rather than a cyberattack. The failure occurred when the FAA&#39;s aging router infrastructure became overloaded with data, an issue reportedly triggered by the recent implementation of a new AI-supported air traffic system. This event marks only the second full nationwide ground stop in the U.S. since the attacks of September 11, 2001.<\/p>\n<p>Major U.S. airlines are facing a logistical nightmare as they work to clear the passenger backlog. Delta Air Lines (<a href=\"\/stock\/DAL\">DAL<\/a>) and American Airlines (<a href=\"\/stock\/AAL\">AAL<\/a>) have each canceled more than <strong>2,200 flights<\/strong>, while United Airlines (<a href=\"\/stock\/UAL\">UAL<\/a>) reported approximately <strong>1,800 cancellations<\/strong>. Southwest Airlines (<a href=\"\/stock\/LUV\">LUV<\/a>) also saw nearly <strong>1,400 flights<\/strong> grounded. Industry analysts suggest the financial impact on the sector could be substantial, given the scale of re-booking requirements and potential compensation claims.<\/p>\n<p>Passengers traveling to or from the United States are strongly advised to check their flight status before heading to the airport. The <strong>UK CAA<\/strong> emphasized that while the &quot;ground stop&quot; is over, the &quot;ripple effect&quot; will be felt throughout the weekend. Airlines are currently prioritizing the repositioning of crew members who reached their maximum permitted duty hours during the standstill, a factor that continues to limit the immediate restoration of full flight schedules.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Key Takeaways Over 15,000 flights impacted globally after the Federal Aviation Administration (FAA) issued a rare
