On Friday, September 17, 2021, United Airlines a “technical system issue” they say was caused an outage that impacted flights nationwide.
The outage frustrated travelers because it prevented them from checking in or boarding flights at certain airports. The mobile United app and website were unavailable, according to many passengers.
“This morning we experienced technical system issues that impacted our operations and have since been resolved,” a statement released by the airline said. “All systems are now working normally and we are working diligently to get customers to their destinations.”
The airline requested a ground stop, according to the FAA website. A ground stop prevents all flights in the U.S. and Canada from proceeding.
The ground stop for the U.S. and Canada began at 5:45 a.m. CT and was issued “due to computer issues.” The ground stop was lifted about 45 minutes later.
