On Mar 27th 2026, an Aer Lingus Airbus A330-300, registration EI-DUZ, operating flight EI-104 from John F. Kennedy International Airport to Dublin, was forced to divert shortly after departure following reports of smoke in the cabin.
The aircraft had climbed to FL370 and was cruising approximately 25 nautical miles north of Boston when the crew detected smoke and made the decision to divert as a precaution. As the flight descended toward Boston, the crew informed air traffic control that the source of the smoke remained unidentified, but conditions in the cabin had stabilized.
Given the circumstances and fuel load, the pilots prepared for an overweight landing, a standard but carefully managed procedure. The aircraft landed safely on runway 04R about 20 minutes after leaving cruising altitude.
After touchdown, the crew reported normal brake temperatures, indicating the landing had been conducted within safe operational limits despite the higher weight. The aircraft then taxied to the apron, where it underwent inspection.
Following approximately 2.5 hours on the ground, the aircraft was cleared to continue its journey and later arrived in Dublin with a delay of about two hours.
Smoke-related events in flight are treated with the highest level of caution due to the potential risks involved. In this case, the crew’s swift and measured response ensured a safe outcome for all on board.
