United Airlines briefly halted all its flights across the United States and Canada late Tuesday night due to what the airline called a “connectivity issue.” The ground stop lasted about 30-36 minutes just before midnight Central Time on September 23.
The Federal Aviation Administration (FAA) issued the stop at United’s request. According to the FAA’s Air Traffic Control System Command Center, the cause was listed simply as “COMPANY REQUEST / TECHNOLOGY.”
This marks the second time in less than two months that United has requested a nationwide ground stop due to technical problems. In early August, the airline experienced a more significant disruption related to its weight-and-balance system that lasted several hours and caused approximately 1,000 flight delays.
United quickly emphasized that Tuesday night’s issue was not related to cybersecurity. A company spokesperson explained that the problem stemmed from “an inability to connect to the airline’s technology network during maintenance.” Connectivity was restored shortly after the brief pause.
The late-night timing of the outage helped minimize the initial impact. During the overnight hours immediately following the ground stop, flight tracking data showed at least 42 delays and 4 cancellations, with Los Angeles International Airport experiencing the most disruptions.
However, as is common with airline operations, even brief technical glitches can create ripple effects throughout the system. By midday Wednesday, delay counts had increased significantly. Flight tracking websites reported more than 170 United flights delayed nationwide, with 14 cancellations. United maintained that only “a small handful” of these delays were directly related to the previous night’s connectivity issue, and no cancellations were attributed to it.
Regional impacts were significant, with flight tracking data showing hundreds of delays at various airports by Wednesday afternoon. United’s major hubs were likely to feel these effects most acutely due to their interconnected flight schedules.

Even short-lived technical failures can cause significant problems by misaligning aircraft and flight crews throughout an airline’s network. When planes aren’t where they need to be, airlines must shuffle resources, leading to additional delays that can persist even after the initial problem is resolved.
Coincidentally, American Airlines reported its own “technical issue impacting some maintenance applications” on the same day. According to The Hill, American’s separate incident contributed to nearly 1,000 flight delays and 63 cancellations by midday Wednesday, though American initially stated that no flights were canceled due to the tech problem.
These back-to-back incidents highlight the increasing dependence of airlines on complex technological systems to manage everything from flight planning to maintenance scheduling. When these systems experience even brief interruptions, the impact can quickly spread across an airline’s entire network.
United’s major hubs in Chicago (ORD), Denver (DEN), Houston (IAH), Newark (EWR), and San Francisco (SFO) typically experience these operational challenges during technical disruptions due to their busy flight schedules.
For travelers, these events underscore the importance of monitoring flight status through airline apps and websites during periods of disruption, as even brief technical glitches can lead to unexpected schedule changes throughout the system.
