A global Microsoft system outage caused widespread flight delays and cancellations at major Florida airports, affecting passengers at Miami, Orlando, Fort Lauderdale, and Jacksonville, while Tampa quickly resumed normal operations.

A global Microsoft system outage caused widespread disruption at several of Florida’s busiest airports on Friday morning, delaying flights and inconveniencing thousands of passengers.

Miami International Airport (MIA) reported significant delays in both departures and arrivals, prompting airport officials to urge passengers to check their flight status with their airlines before heading to the airport. Travelers were also advised to consider alternative travel arrangements where necessary.

“Due to a global Microsoft system outage, departures and arrivals at Miami International Airport are currently delayed,” airport officials said in a statement.

Orlando International Airport (MCO), another major hub, reported a moderate impact. Despite MCO’s IT systems remaining unaffected, the outage led to 74 delays and 65 flight cancellations. Airport authorities said they are collaborating with airline partners to assist passengers and restore normal operations as The Federal Aviation Administration is monitoring the situation and working with airlines to mitigate further disruptions.

Fort Lauderdale-Hollywood International Airport was also affected, with expectations of flight delays. Jacksonville International Airport reported operational disruptions but remained open. Contingency procedures were being implemented to address flight disruptions, and passengers with early morning flights were advised to check with their airlines for the latest updates.

Tampa International Airport, meanwhile, reported that it managed to resume normal flight operations shortly after the initial glitch.

The Microsoft system outage, which affected multiple airports across the United States, was traced back to a networking issue in the Europe, Middle East, and Africa region. The issue disrupted access to various Microsoft 365 services, impacting airline operations and causing significant delays and cancellations.
