Long lines were reported at airports nationwide. Agents gave handwritten boarding passes to many passengers.
CNN reports 4,900 flights were impacted by the problem worldwide. At O'Hare International Airport in Chicago United passengers experienced delays of 15 minutes to five hours.
Speaking at a Women in Transportation seminar downtown, Chicago Aviation Commissioner Ginger Evans said United immediately contacted the Chicago Department of Aviation and helped provide extra staffing during the outage.
United issued a statement saying:
"We experienced a network connectivity issue this morning. we are working to resolve this and apologize to our customers for any inconvenience."
