Flights are getting back to regular operations at Denver International Airport although there may still be lingering problems from an overnight global Microsoft outage.
Some flights were grounded in the overnight hours and into the morning. American, Southwest and Frontier flights were operational by 7 a.m. and United and Delta flights were no longer grounded at 8 a.m.
Companies that rely on Microsoft 365 apps reported widespread outages early Friday, and that includes airlines across the country and across the world.
FAA and TSA operations at Denver International Airport were functioning normally.
