Flights affected by computer glitch
United Airlines is reporting computer problems that are affecting flights across the United States.
On its Twitter page, United reported the computer outage was interrupting departures, airport processing and reservations.
Attempts to access the airline's website are also being stymied.
The computer problems apparently started a little after 7pm on Friday in Chicago, resulting in long lines of passengers at check-in counters at O'Hare International Airport, one of United's largest hubs.
United said it is attempting to resolve the issue.
