Major US carriers including American Airlines, Delta Air Lines and United Airlines issued ground stops on Friday morning citing communication issues, less than an hour after Microsoft resolved its cloud services outage that affected several low-cost carriers.
It was not immediately clear whether the call to keep flights from taking off were related to the earlier Microsoft cloud outage. Apart from American and Delta, UAL and Allegiant Air also grounded flights.
The Federal Aviation Administration did not immediately respond to Reuters' request for comment.
Low-cost carriers Frontier Airlines, a unit of Frontier Group Holdings, Allegiant and Sun Country earlier reported outages that affected operations. Frontier said late on Thursday it was resuming normal operations and the ground stop had been lifted.
Frontier said earlier a “major Microsoft technical outage” hit its operations temporarily, while Sun Country said a third-party vendor affected its booking and check-in facilities, without naming the company.
