This marks the second smoke-related issue to impact a Delta flight within a week, just two days after an Australia-bound flight returned to Los Angeles due to smoke on the plane.

A Delta Air Lines flight to Columbia, South Carolina, was forced to return to Hartsfield-Jackson Atlanta International Airport on Monday morning after a “haze” was observed inside the plane, according to officials.

A Delta Air Lines flight returned to Atlanta on Monday morning shortly after takeoff when the crew reported "possible smoke" in the aircraft, according to the Federal Aviation Administration, just two days after another Delta flight was diverted due to smoke on the plane.
