United responded to a customer on X on Monday that it was “experiencing a system glitch affecting our online tools.”

United told CNBC that some of its internal systems were temporarily affected by the outage and that it was using backups to end the disruption. “Our teams are working to get our customers on their way,” the airline said.

Delta said mid-morning that it experienced some “minor” delays Monday due to the outage but “does not anticipate any significant impact to future customers as a result of this event.”
