London, United Kingdom: On October 5, 2025, Delta Air Lines flight DL59, an Airbus A330-900neo (registration N411DX), faced an emergency shortly after leaving London Heathrow Airport for Boston Logan International Airport. About 38 minutes into the flight, while flying over the southwest coast of England near Cornwall, the flight crew noticed fumes in the cockpit. Following standard safety procedures, the pilots put on oxygen masks and decided to return to London immediately. The plane safely landed back at Heathrow around 10:35 AM local time, roughly 1 hour and 35 minutes after takeoff. Emergency ground services were ready as a precaution. Passengers were safely disembarked and bused back to the terminal. Delta Air Lines confirmed the incident in a statement, explaining that the flight returned due to reports of smoke inside the aircraft. The airline apologized for the inconvenience and stressed that passenger safety is their top priority. This incident comes amid Delta’s recent efforts to address problems with contaminated cabin air. The airline has been replacing auxiliary power units (APUs) on its Airbus A320 fleet to prevent toxic fume events, which have previously been linked to neurological and respiratory issues in passengers and crew. Currently, no injuries have been reported among passengers or crew. Investigations are ongoing to determine the exact cause of the fumes in the cockpit.
