Hundreds of flights across US delayed after major IT outage at 5 airlines

  • Hundreds of flights were delayed on Monday morning after several major airlines experienced an IT issue with a service called AeroData.
  • The affected airlines include American Airlines, Southwest Airlines, Delta Air Lines, United Airlines, JetBlue, and Alaska Airlines.
  • More than 500 flights were behind schedule at airports in Chicago, New York, Texas, Boston, Atlanta, Miami, and Detroit.
  • Passengers started reporting on delays linked to a nationwide IT problem at about 3.30 a.m. Five hours later, the Federal Aviation Administration said the issu was resolved.
Flights at airports across the US were delayed early Monday because of an IT failure affecting at least five airlines, the US Federal Aviation Administration (FAA) said. Southwest Airlines, Delta Air Lines, United Airlines, JetBlue, and Alaska Air were hit, causing widespread delays, the authority told Business Insider. “Several airlines are experiencing issues with a non-FAA flight planning weight and balance program called AeroData. Mainline operations and regional operations are affected to varying degrees,” a spokeswoman said.
The FAA tweeted the issue was resolved at 8:34 a.m. ET on Monday, around five hours after passengers first began posting to social media describing IT problems affecting their flights.
While the problem was still going on, airlines responded to passengers on Twitter, blaming a computer administration issue:

Thanks — I meant ETA on the system outage the gate agent identified. It’s 6:27 and we’re still waiting to board. It’s clear we’re not leaving in 3 minutes.

AeroData, the software behind the outage, is used to calculate the weight and balance of flights before takeoff. It also provides runway analysis and aircraft performance data for airlines, according to AeroData’s website. The company, based out of Arizona, provides data for over 50% of all North American flights, and says that will rise too 85% soon. A 2017 company press release said just five minutes of AeroData system downtime can result in over 100 delayed flights and loss of revenue. Business Insider contacted AeroData for comment but received no response. Numerous airlines named the software, as did the FAA.
