Delta, Southwest flights at SMF delayed due to AT&T outage

Internet outages are causing delays for some flights at the Sacramento International Airport (SMF), officials said. SMF said the outages are affecting flights for Southwest and Delta airlines. While a cause for the outage was not released, an AT&T outage map shows the estimated time of restoration is 4:49 p.m. Thursday. That does not necessarily mean flights will be impacted for that long.
