SWISS is accelerating its A330 retrofit to the SWISS Senses cabin, starting in the coming weeks. The new configuration introduces First Class suites and Premium Economy, reducing total seats to 225

## Summary

SWISS management has confirmed that its Airbus A330-300 fleet will begin reconfiguration into the SWISS Senses cabin (identical to Lufthansa Allegris) in the coming weeks, accelerating from the previously planned 2025-2026 winter season. The project is expected to move into full motion by mid-2026, with one aircraft reconfigured every six weeks. The entire A330 fleet of 14 planes is expected to be completed by late 2027 or early 2028. The new A330 configuration will feature 225 seats, a reduction from the current 236. Key changes include:
- First Class: Reduced from 8 seats to 3 suites (including one double suite).
- Business Class: Reduced from 45 to 43 seats.
- Premium Economy: New cabin with 28 seats.
- Economy: Reduced from 183 to 151 seats. A notable engineering detail is the installation of a 1.5-ton weight in the rear of the aircraft to compensate for the weight of the new First Class suites, which are reportedly too heavy for the plane's balance without it. The article notes that the subsequent retrofit of the Boeing 777-300ER fleet timeline remains undetermined
