Frontier asked the Federal Aviation Administration to implement a ground stop for its flights across the United States which applied to all destinations. According to FlightAware, the airline ended up canceling nearly 20% of its flights on Thursday and 27% were delayed.
Allegiant only had to cancel 2% of its flights yesterday while 44% were delayed. It informed customers that due “the Microsoft Azure issue” that its website was “currently unavailable.” Sun Country Airlines said that as a result of “a global outage” at one of their information vendors “some of our services are temporarily unavailable.”
American, Southwest and United Airlines all said that they were unaffected by the Microsoft outage.
The ground stop by the Federal Aviation Administration for Frontier flights was lifted at 10 pm. So far this morning, operations at the airline appear to be relatively unaffected with minimal delays or cancels.
