Overview

• SWISS’s new first-class option pairs the center Suite Plus with a window Single Suite across the aisle to form a larger area for up to three passengers.
• The combined setup debuts on Zurich–Boston A350-900 flights at the start of 2026, with retrofits planned for A330-300s and 777-300ERs.
• Reservations for the Grand Suite are restricted to the SWISS First hotline and are not available online.
• The footprint is reported at about 63.5 square feet, featuring nearly six-foot walls, a double bed in Suite Plus and a private wardrobe.
• Reviewers question the privacy claims since an aisle separates the suites and a single first-class lavatory is shared, while award redemption availability remains unclear and likely limited.
