Overview
- Crew of SWISS Flight LX9 declared a general emergency with transponder code 7700 and turned toward the Azores before landing safely at Lajes Air Base on Tuesday after detecting a pungent odor in the economy cabin.
- All 222 passengers and 16 crew disembarked normally and about five passengers and one crew member received brief medical checks for eye irritation, nausea or headaches with no one needing further treatment.
- The aircraft involved is a Boeing 777-300ER (registration HB-JNF) that had flown from Zurich to Chicago earlier and was operating the overnight return to Zurich when the diversion occurred.
- SWISS dispatched a replacement plane to collect passengers, cancelled the affected Zurich–Chicago flight LX8 and the aircraft's subsequent return, and said technical teams are inspecting the jet to find the odor source.
- The airline stressed the diversion was precautionary and said investigations are ongoing, a development that follows recent SWISS long‑haul incidents involving unexplained smoke or odors that required post‑flight probes.
