ATLANTA- Delta Air Lines (DL) passengers faced widespread delays on Friday as all departures at Detroit Metropolitan Wayne County Airport (DTW) were halted following a major systems outage. The ground stop affected only Delta operations at the McNamara Terminal, even as other carriers at DTW continued normally.
Delta (DL) said the issue stemmed from a local connectivity failure at Detroit (DTW), while a separate technology breakdown in the United Kingdom forced a Delta flight bound for Edinburgh Airport (EDI) to divert. Both events added pressure on the carrier’s global operation.
Delta Flight Delayed at Detroit
The FAA issued the initial ground stop for DTW around 5 a.m. local time after Delta reported system failures that prevented normal departures.
The agency first anticipated lifting the restriction by 7 a.m., then pushed it to 9 a.m., noting a significant chance the stop could extend further. FAA data later showed a rapid increase in cumulative delay minutes as the outage persisted.
Delta confirmed a full pause of flights at DTW in its 8:45 a.m. update, citing a technical connectivity issue inside the terminal.
By 9:40 a.m., the airline reported that operations were resuming and that a travel waiver had been issued for customers flying through Detroit on December 5 and 6. The carrier advised passengers to continue monitoring updates through its app and website.
Another Incident
While Detroit grappled with system failures, Delta Flight 208 from New York to Edinburgh experienced a separate disruption linked to a UK air traffic control outage.
The Boeing 767 circled near Edinburgh (EDI) before abandoning its approach and diverting to Dublin, where it landed just after 10 a.m. local time.
Edinburgh Airport confirmed an air traffic control technology issue that temporarily halted all operations.
Unrelated Global Internet Outage Adds Confusion
A widespread outage at Cloudflare, which disrupted major websites worldwide, raised questions about possible links to Delta’s issues.
No connection has been confirmed. Monitoring site Downdetector did show rising reports of Delta computer outages affecting check-in systems and the airline’s website.
Delay and Cancellation Numbers Rise
FAA data and FlightAware listings highlighted escalating operational strain. By early morning, Detroit recorded 64 delays and 49 cancellations, while nationwide figures for Delta included more than 700 delays and 100 cancellations.
Travelers voiced frustration online, describing blank terminal screens, missing announcements, and crews waiting without information.
European Airports Report Knock-On Effects
Edinburgh Airport (EDI) also faced hours of disruption, with takeoffs and landings halted for about two hours due to an air traffic control issue.
Although only a small number of flights were canceled, nearly one-third of all departures were delayed.
A Combined Operational Challenge
The technology failures on both sides of the Atlantic created a complex network of delays for Delta customers.
As systems stabilized, the airline focused on restoring schedules and supporting affected travelers through rebooking options and its operational waiver.
