On August 6, 2026, the FAA briefly halted flights into and out of the airspace managed by Minneapolis Air Route Traffic Control Center after a telecommunication equipment outage, and evening thunderstorms over the Northeast triggered separate ground stops at Newark, LaGuardia, and JFK. Together, the two disruptions canceled more than 1,000 flights nationwide on Thursday, with over 560 more cancellations reported by Friday morning.
A center outage, not just an airport outage
The FAA said it “briefly paused flights into and out of Minneapolis Air Route Traffic Control Center’s airspace due to telecommunication issues,” adding that the cause of the outage was not yet known. The pause began around 2 p.m. local time and was lifted by 4:15 p.m., though arrivals at Minneapolis-St. Paul International still faced roughly 90 minutes of delay once traffic resumed.
The disruption reached well beyond Minnesota because an Air Route Traffic Control Center manages enroute airspace across several states, not just the ground around one airport. Departures bound for Minneapolis from centers covering Los Angeles, Chicago, New York, Dallas, Atlanta, and Denver were held or diverted, along with flights originating in Halifax, Ottawa, Montreal, and Toronto.
Storms piled onto the Northeast the same evening
Separately, thunderstorms moving through New York and New Jersey Thursday evening prompted ground stops for departures to Newark, LaGuardia, and JFK. LaGuardia’s stop lifted around 8:30 p.m., while Newark and JFK remained in effect past 10 p.m., with ground delays at Newark Liberty averaging close to five hours, partly attributed to staffing.

Minneapolis Center pauses traffic. The FAA halts flights into and out of its airspace over a telecommunication outage of undetermined cause.

Systems restored. The ground stop lifts, but arrivals face roughly a 90-minute average delay.
Thursday evening
Storms hit the Northeast. Ground stops follow at Newark, LaGuardia, and JFK as thunderstorms cross New York and New Jersey.
Friday morning
The tally keeps climbing. Over 560 additional cancellations are reported nationwide, led by LaGuardia, Reagan National, Newark, JFK, and Orlando.
Why one outage becomes a nationwide problem
Both events are examples of the same mechanism: the FAA’s ground stop and flow control system deliberately holds aircraft on the ground elsewhere in the country rather than let them fly toward a bottleneck they cannot land at. That containment strategy is safer than letting traffic stack up in the air, but it means one facility’s bad afternoon shows up as cancellations at airports hundreds of miles away.
By Friday morning, Delta had logged 104 cancellations and 180 delays tied to the Minneapolis outage, United reported 79 cancellations and 1,104 delays systemwide, and JetBlue had canceled 128 flights. JFK, LaGuardia, and Newark ranked among the hardest-hit airports as the two disruptions overlapped.
Delta said travelers rebooking by August 11 in the same cabin would have fare differences waived, and United offered to waive change fees and fare differences for trips originally scheduled between August 5 and 10.
Still developing
As of Friday morning the FAA had not identified the root cause of the Minneapolis Center telecommunication outage. Delay totals were still climbing, and this article reflects figures reported at time of writing.
