Inside Thai Airways’ New Royal Silk Class: What the 4 Business First Suites Add, and When They Actually Fly

Thai Airways unveiled its new cabins in September 2026, built around the Thompson Aero VantageNOVA business class seat in a 1-2-1 layout, with a sliding privacy door and direct aisle access at every seat. The front row of the cabin is branded Business First, just 4 suites per aircraft, with a 32-inch screen against 24 inches elsewhere, and it replaces the 8-seat Royal First Class cabin. Service begins in mid-2027, starting on the Boeing 777-300ER.

Thai Airways’ 4 New Cabins Step Down From a 32-Inch Screen to a 13-Inch One

The new interior is arranged in 4 tiers, and screen size is the clearest line drawn between them:

• Business First — a 32-inch screen, only 4 suites per aircraft, in the first row of the business cabin

• More floor space and legroom than a standard business suite, a longer bed, and Bluetooth audio streaming

• Royal Silk Class — a 24-inch screen, 1-2-1 layout, sliding privacy door at every seat

• Window suites face outboard, while the 2 centre suites can be opened up to each other

• Premium Economy — a 16-inch screen

• Extended privacy wings around the headrest, in a cabin Thai Airways is only now adding to its widebody fleet

• Economy Class — a 13-inch screen

• Carried over in the same design language and colour palette as the cabins ahead of it

What Is the Seat Called, and Has Any Airline Flown It First?

The seat is the VantageNOVA from Thompson Aero Seating of Northern Ireland, and the detail most coverage skips is that Thai Airways is not the platform’s launch customer. Thompson Aero announced on 13 April 2026 that Delta Air Lines would launch VantageNOVA on its Airbus A350-1000s, though at that point the seats were still in final design review and not yet flying. So the claim that no airline is operating the seat in service is accurate.

The 8-Seat Royal First Cabin Is Going Away, Replaced by Just 4 Business First Suites

This is the bigger change, and it is not a design one. Reporting from the unveiling says Thai Airways’ Boeing 777-300ERs, which carry 8 Royal First seats today, will no longer have a first class cabin at all. In its place, the 4 suites in the first row of the business cabin are built out as something more generous. The number of top-tier seats on the same aircraft therefore falls from 8 to 4, a drop of half.

What Business First adds is floor space, legroom, bed length and that 32-inch screen. What goes is a separate cabin and the service that came with it. For a regular first class passenger, this is a different product to plan around rather than a reupholstered version of the old one.

Where Should a Regular Royal First Passenger Look Now?

Anyone who still wants the best seat on the aircraft has to secure one of the 4 front-row suites, and competition for them will be sharper because there are half as many. The other route is to look at carriers that still run a full first class cabin on the same city pairs, which mostly means European and Middle Eastern airlines on the long-haul routes out of Bangkok.

A 32-Inch Screen Is Only 33% Longer Than a 24-Inch One, yet It Has 78% More Surface

Screen sizes are measured across the diagonal, not by area. A 32-inch panel is therefore 33% longer on the diagonal than a 24-inch one, but because area scales with the square, it works out at 1.78 times the surface, or 78% more. That is the difference a passenger actually notices during a film, rather than the 8 inches the spec sheet shows.

Run it across the whole aircraft and the gap widens. The 32-inch panel in Business First has 4 times the surface of the 16-inch screen in premium economy and 6 times that of the 13-inch screen in economy, even though the inch figures look far closer than that.

Can Passengers Pair Their Own Bluetooth Headphones?

Yes. Thai Airways says the new seats support Bluetooth audio streaming, which removes the need for a 3.5 mm adapter or the airline’s own headset. It is a small detail that frequent flyers feel within the first hour, since a passenger’s own noise-cancelling headphones usually outperform what comes with the seat.

Unveiled in 2026, but the Fleet Will Not Be Finished Until 2029

The seat does not arrive across the fleet at once. It follows the cabin retrofit programme and the delivery schedule for new aircraft:

One caveat is worth keeping in mind. Thai Airways ordered 45 Boeing 787-9s back in 2024 and took delivery of the first on 30 June 2026, but the new cabin only enters service in mid-2027, so aircraft delivered before then do not carry it. Seeing a 787-9 on the schedule is not confirmation on its own.

Will a Ticket Booked for Next Year Come With the New Seat?

Not reliably. Mid-2027 is when the rollout starts, not when every aircraft is ready. The safest approach is to check the seat map for that specific flight at the time of booking and see whether it shows the 1-2-1 layout with a Business First row, and to allow for an aircraft swap before departure, which happens often while a fleet is being refitted.

This Cabin Will Be Judged on Its First Row, Not on the Whole Aircraft

Every business seat gets the same privacy door and the same 1-2-1 layout, which is the standard its peer group already meets. What changes the conversation is the 4 front-row suites standing in for first class, because they move the line for what counts as the best seat on a Thai Airways aircraft squarely into the business cabin.
