A Delta Air Lines flight from Los Angeles was forced to return to its departure airport after smoke was detected on board. The Airbus A350-900 aircraft, carrying 162 passengers, took off shortly before 9:00 p.m. and landed safely at LAX about 30 minutes later. Despite the issue being confined to the galley, pilots requested medical attention for passengers who may have been affected by the smoke. All passengers are being reaccommodated on a different flight, with Delta apologizing for the delay in their travels.
