Delta Air Lines, Inc.’s Chief Operating Officer Mike Spanos is leaving the company after a little over a year in the job, the company said in a filing Friday. 

The airline doesn’t currently have plans to replace Spanos, according to a memo from Chief Executive Officer Ed Bastian. Instead, two of his executives will now report to the CEO: John Laughter, chief of operations, and Allison Ausband, who heads the customer experience division.

Spanos is leaving Delta in early September to take a position at another company, Bastian said in the memo.

The Wall Street Journal first reported news of Spanos’s departure.
