United Airlines leaned on real-time data to recover from the CrowdStrike outage

United Airlines wasn’t thinking about software updates, threat detection or IT outages when it prioritized real-time data capabilities in its technology strategy. CIO Jason Birnbaum had customer experience enhancements and operational efficiencies top of mind.

“Our customers wanted and craved information,” said Birnbaum. “We needed better ways to deliver it faster and with more accuracy in a language that they understood — not just airline jargon.”

United was also focused on delivering real-time data to its own employees, both in times of normal operations and in weather-related crises. A bad patch from cybersecurity provider CrowdStrike that brought down millions of computers in the predawn hours of July 19 wasn’t on Birnbaum’s radar.

“We get disrupted all the time, whether it’s a hurricane or a snowstorm or whatever. We have to be ready to make decisions and recover quickly,” Birnbaum told CIO Dive. “We had invested in our recovery capabilities, reinforced by communication across different network groups. We all have the same data and we’re all looking at the same screen, so there were a lot of elements we were able to leverage in a very tough situation.”

CIOs put technologies and processes in place to keep the business running when problems arise. The CrowdStrike event was a painful reminder that it’s hard to prepare for the unpredictable.

Airlines were a particularly hard hit. United had to ground nearly 700 flights on Friday, July 19, and more than 700 over the following two days, according to FlightAware’s tracking service. But, while Delta grounded more than 1,000 flights on Monday, July 22, and hundreds more the following day, United’s daily cancellations fell below 100.

The restoration took agility and an ability to mobilize quickly. Teams of technicians were dispatched to reboot more than 26,000 computers and endpoint devices at 365 airport locations, United CEO Scott Kirby detailed in an open letter just three days after the crisis began.

“We have an organization that supports the field, but we don’t have people in every location,” Birnbaum said. “They got in their cars, they drove to places, some brought their kids along, and they did whatever they could to keep it going. There’s no official scorecard, but my reading of the situation is that we were one of the fastest in the industry to recover.”

From cloud to the edge

United’s modernization journey took flight in the cloud. IT led the company to an enterprisewide rethink of decision making and data sharing. The broader goal was to give customers more up-to-date information and help crews keep planes running on time.

The airline chose AWS as its preferred cloud vendor in 2021 and was nearing the end of a long migration in April, when CFO Mike Leskinen reported that between 70% and 90% of its workloads were in the cloud.

Less than 24 hours before the CrowdStrike outage began, during a July 18 earnings call, Kirby and Leskinen praised the company’s IT and operations teams for reducing the recovery time and costs of periodic disruptions.

As United upgraded technology and processes, Peter Weill, a senior research scientist at MIT Sloan School of Management and chairman at MIT CISR, was exploring the advantages of real-time businesses. Birnbaum attended a presentation by Weill and saw parallels that put United on the researcher’s radar.

“Jason stood up and said, ‘Wait, that’s what we’re trying to do at United,’” Weill said in an interview with CIO Dive.

Weill’s research focused on the user experience improvements Birnbaum had prioritized.

“When we did the research, it wasn’t really about crisis or risk,” Weill said. “It focused on how you make customers and employees happier and more agile. They are much happier if they get an answer immediately, whether it’s about a plane or a payment.”

While rooted in cloud, United’s improvements were tied into the edge technologies that gave teams access to real-time data and communications.

“We wanted to be better at turning our aircraft — fueling, fixing, catering and getting everyone boarded. There are roughly 250 different data points we want to measure in real time,” Birnbaum said.
