WASHINGTON – Air travel across US remained disrupted over weekend as airlines struggled to recover from nationwide aviation shutdown caused by major telecommunications failure, leaving thousands of passengers facing canceled flights, extended delays and uncertain departure schedules.
Federal Aviation Administration (FAA) lifted its nationwide ground stop late Friday after restoring affected air traffic control systems. However, the five-hour interruption caused widespread disruption at some of America’s busiest airports, with Chicago, Atlanta, Dallas, Denver and Los Angeles among the hardest-hit destinations.
The telecom outage affected air route traffic control centres. FAA responded by suspending departures nationwide, resulting in what was described as the longest such ground stop in 25 years. The effects of the aviation shutdown were felt across the country, particularly at major airline hubs handling large volumes of domestic and international passengers.
Chicago O’Hare, Atlanta’s Hartsfield-Jackson, Dallas/Fort Worth, Denver International and Los Angeles International airports recorded massive cancellations and delays. Other affected airports included New York’s John F. Kennedy and LaGuardia, San Francisco International, Boston Logan and Newark Liberty. Additional disruptions were reported in Miami, Pittsburgh and Baltimore.
Chicago O’Hare experienced particularly severe operational difficulties, with more than 700 flights canceled on Friday. Travelers at Chicago Midway also faced prolonged waiting periods after air traffic restrictions were removed.

Chicago O’Hare Flights Canceled
Chicago O’Hare’s departure information revealed considerable disruption to regional routes, particularly American Eagle services connecting major cities with smaller destinations.
Flights to Madison, Denver and Green Bay were canceled, while the American Airlines service to Cincinnati was postponed from 10:15 p.m. until 5:28 a.m. Indianapolis-bound flight AA2805 was delayed until 2:31 a.m. International services also experienced cancellations, including Volaris flight Y4703 to Mexico City and Viva flight VB547 to Guadalajara.

Although FAA resumed normal air traffic control operations following the telecommunications failure, airlines continued dealing with the consequences of the shutdown on Saturday. The suspension left aircraft and crews out of position, forcing airlines to revise departure schedules and manage accumulated passenger traffic.
Some early-morning services resumed on time, but cancellations and delays continued to affect domestic and international travel. The disruption also highlighted concerns about the reliability of aging US aviation infrastructure and the potential consequences of technical failures at critical air traffic control facilities.
