Greenville, S.C. — Authorities say a Delta Air Lines plane with 259 passengers on board landed safely at Greenville-Spartanburg Airport on Wednesday evening after the pilot smelled smoke in the cockpit.

Airport Manager Larry Holcombe said Delta Flight 1819 was flying from Raleigh to Atlanta when the pilot made the emergency landing without incident around 5 p.m. Wednesday.

Holcombe says the problem appeared to be a malfunction in an air-conditioning vent. He said one woman reported minor burns, but was treated on the scene.
