SWISS is introducing two distinct, fully enclosed First Class suites – rolling out first on the Boston – Zurich route at the start of 2026, and already bookable.

The Single Suite (window side) and Suite Plus (center) can be combined into a single semi‑private unit dubbed the “First Grand Suite.” Suite Plus accommodates a double bed and offers a private wardrobe, while both suites are structured to feel like your own “loft aloft.”

You can book both suites—Single Suite plus Suite Plus—as one combined space, using the shared aisle access. It’s pitched as a private zone that functions as bedroom, office, or meeting space.

• Single Suite (2.4 m²) → ~25.8 sq ft
  
• Suite Plus (3.5 m²) → ~37.7 sq ft
  
• Combined “Grand Suite” is roughly 63.5 sq ft, though not seamlessly joined, since there’s an aisle in-between.

The Suite Plus is about the size of the individual Lufthansa Allegris First, while the combined space is smaller than Singapore’s A380 Suites in double configuration with wall between the beds down (97 sq ft) and smaller than Etihad’s Residence (125 sq ft).

It does seem odd to book out two first class seats that are separated by an aisle, so not really “private as never before” as the marketing goes.

The product launches on the new Airbus A350‑900 aircraft, and they say they’ll retrofit Airbus A330‑300 and Boeing 777‑300ER aircraft with the product “gradually.” Booking is available now via reservations (not online) for travel starting January. It seems like they might prioritize New York JFK, Tokyo Narita and Singapore in the future.

Meanwhile business class gets differing products, some with sliding doors, along with lie‑flat beds, heating/cooling, full aisle access, and various storage options. I expect a similar mish mosh to Lufthansa, their corporate parent.

Swiss has cranked up its First Class game by engineering a two-suite combo that masquerades as a “private loft.” Smart marketing, but they didn’t reinvent the wheel. Enclosed suites are premium, and a double bed and wardrobe setup is a solid step up from the current product. Still, it doesn’t seem quite worth paying for the full footprint given that these are two seats across the aisle – we’ll see how it sells (and Boston doesn’t seem like the ideal test both in terms of market or length).

Swiss does not allow First Class award bookings using miles from partner frequent-flyer programs except in rare circumstances. Even within the Miles & More program, only elite tiers—Senator and HON Circle—can redeem miles for Swiss First Class awards. If you’re a regular member with miles, you’re out of luck. Swiss occasionally releases First Class award space to partners and general members for the São Paulo (GRU) → Buenos Aires (EZE) route. I do not expect them to release these new suites as awards for some time, even at the new higher pricing that went into effect in June.
