Major U.S. airlines were back up and running on Monday after a system-wide outage delayed hundreds of flights and fired-up customer complaints on social media, the second such disruption in a week.
The Federal Aviation Administration said the root of the problem was caused by the program provided by Scottsdale, Arizona-based AeroData Inc. that helps airlines measure and manage weight and balance.
The agency released a statement around 8:30 a.m. ET, saying the issue had been resolved and an FAA spokesman said it plans to look into the outage.
