United Airlines is having computer problems that are affecting its operations at airports and its website.
The airline says it has a "network outage." Its main website, United.com, was down. It says it is trying to minimize any impact to its operations.
An airline spokeswoman did not immediately have more details about the problem.
The state Department of Transporation said about three to four flights were affected. There's about a half-hour delay on each of the flights.
