An unspecified problem with its passenger computer system delayed United Airlines flights across the country on Tuesday, compounding existing weather-related woes.
“We are experiencing issues with our passenger service computer system. We are working to resolve this as quickly as possible and apologize to our customers for any inconvenience,” the airline said in a statement.
Social media lit up Tuesday morning with complaints from passengers stranded at various airports. The Chicago Sun-Times reported delays in Chicago, Denver, Los Angeles and Washington, among other places.
United’s Twitter staff responded to most complaints with “We’re experiencing intermittent system-wide issues.” Further details were not immediately available.
