(Reuters) -Delta Air's chief operating officer, Mike Spanos, will leave the airline next month to take on a role at another company, CEO Ed Bastian said in a memo to employees on Friday.

Spanos had approached him earlier this summer to communicate that he was considering other opportunities, Bastian said.

The exit of Delta's operations chief comes weeks after the airline canceled thousands of flights owing to a global cyber outage.

Spanos joined the legacy carrier last year and had previously worked as the CEO of amusement park chain Six Flags , before stepping down in 2021.

He had also spent more than 25 years in a number of leadership roles at PepsiCo and the Pepsi Bottling Group.

Delta currently does not plan to appoint someone to replace Spanos, the memo showed.
