United Airlines to complete cloud migration soon

United Airlines has almost completed its cloud migration as CFO Mike Leskinen revealed the company has migrated 70-90 percent of its workloads to the cloud, with the rest still on-premise.

The company has had a challenging first quarter and is now attempting to offset those costs with "great operation," including some "longer term cost initiative that [the company] has started."

"We've got significant opportunities within our technology organization to help drive efficiencies throughout the full airline, but one that I'll highlight is moving a lot of our mainframe computing into the cloud," said Leskinen. However, he went on to note that "you don't save the cost of moving to the cloud until you shut the mainframe down."

Leskinen added: "In many cases, we've moved 70, 80, or 90 percent to the cloud, but we still have to maintain that mainframe with 10 percent or 20 percent of the systems on that mainframe." Leskinen said the company would share more information about this at its upcoming investor day on May 1.
