SACRAMENTO (CBS/AP) — Flights out of the Sacramento International Airport on Sunday were delayed due to an internet outage during one of the busiest holiday travel weekends, a spokeswoman said.

Airport spokeswoman Samantha Mott said Sunday that AT&T experienced outages in Sacramento after a vehicle crash took out a utility pole Saturday night. The company did not give the airport an estimate of when internet service would return, she said.
