WASHINGTON/CHICAGO, Jan 11 (Reuters) – U.S. flights have begun to slow takeoffs. All flights departing from the United States were grounded after the Federal Aviation Administration (FAA) scrambled to fix a system outage overnight.
More than 7,300 flights were delayed and 1,100 canceled, according to the FlightAware website, industry officials said.
The total is still rising and according to several airlines, the outage could cause delays at least until Thursday, officials said.
The cause of the problem with the pilot-alert system was unclear, but US officials said they had not yet found any evidence of a cyber attack. US Transportation Secretary Pete Buttigieg told CNN there were “irregularities” with safety messages sent to pilots overnight.
He said the ground stop was “the right call” to make sure messages were moving properly and that there was no direct evidence of a cyber attack.
The outage occurred at a typically slower time after the holiday travel season, but demand remains strong as travel continues to recover to pre-pandemic levels.
The FAA said in a tweet that regular air traffic operations are resuming.
The outage will affect traffic until Friday, said Capt. Chris Torres, vice president of the Allied Airmen’s Association.
“This thing was lifted at 9 a.m. Eastern. That doesn’t mean the problem will stop at 9 a.m. It’s going to have ripple effects,” said Torres, who flies members for American Airlines.
One problem airlines face is trying to get flights into congested gates, causing further delays. Group time limit rules can also be a factor.

“America’s transportation network is in need of significant upgrades,” said Jeff Freeman, president of the American Travel Association, in a statement. “We call on federal policymakers to modernize our critical air travel infrastructure.”
American flyers have a few alternatives. Driving distances are very long and the country’s commuter rail network is thin compared to other countries.
The outage had limited impact on transatlantic routes, as European carriers including Lufthansa, Air France, Iberia and British Airways said flights in and out of the US would continue. Virgin Atlantic warned that some flights may be delayed.
Senate Commerce Committee Chairwoman Maria Cantwell, a Democrat, said the committee would investigate. Republican Senator Ted Cruz called the failure “absolutely unacceptable” and said the issue would lead to reforms as part of FAA reauthorization by September.
An operational meltdown at Southwest late last year left thousands stranded. A severe winter storm before Christmas combined with the Texas-based carrier’s dated technology led to the cancellation of 16,000 flights.
