A SWISS Boeing 777-300ER, registered HB-JNF, operating Flight LX9 from Chicago to Zurich, diverted to Lajes Airport (TER) in the Azores on August 25, 2026. The flight crew declared an emergency to obtain priority air traffic control handling after a pungent odor spread through the economy cabin. The aircraft landed safely at 06:30 local time.
All 222 passengers and 16 crewmembers disembarked normally. SWISS reported that approximately five passengers and one crewmember underwent precautionary medical examinations after experiencing brief symptoms including eye irritation, nausea, and headaches, though none required further treatment. The airline dispatched a replacement aircraft to collect the passengers while investigating the source of the odor, and cancelled its August 25 LX8 round-trip service.
