Summary
Turkish Airlines has confirmed it will begin installing the TCI Crystal business class suite — developed entirely by its in-house subsidiary, TCI Aircraft Interiors — starting with Boeing 777-300ER retrofits in early 2025 and line-fitting on new Airbus A350-1000 deliveries from late 2026. The suite offers a 23-inch-wide seat, sliding privacy doors, a 22-inch IFE screen, wireless charging, and a fully lie-flat bed in a 1-2-1 staggered configuration — expanding suite availability from just 4 aircraft today to over 100 across the widebody fleet.
The rollout timeline is accelerating: the first A350-1000 delivery arrives in July 2026, and if Crystal suites are confirmed on that aircraft, nonstop Istanbul–Sydney service could launch with full suite access by Q4 2026. Premium economy via the TCI Royalux seat follows on new A350 deliveries from 2028.
Turkish Airlines is about to close the gap between its celebrated catering and its long-inconsistent seat hardware — and it’s doing so entirely on its own terms. The carrier has confirmed that its in-house subsidiary, TCI Aircraft Interiors, has developed the Crystal business class suite, a fully enclosed product with sliding privacy doors that will begin appearing on retrofitted Boeing 777-300ER aircraft in early 2025 and will be line-fitted on new Airbus A350-1000 deliveries from late 2026.
The significance here extends beyond seat specifications. Until now, Turkish Airlines operated five distinct business class products across its widebody fleet — a patchwork of Safran, Stelia, and Collins Aerospace hardware, with only four ex-Aeroflot A350-900s offering suites with sliding doors. The Crystal suite changes that calculus entirely, bringing enclosed privacy to a fleet that will eventually exceed 100 widebody aircraft.
The airline’s chair of the board and executive committee confirmed the rollout in a direct briefing, describing the new product as combining “better leg space, better screen HDs, and more privacy.” Fifteen A350-1000s are on order — eight configured for ultra-long-haul operations targeting nonstop Istanbul–Sydney and Istanbul–Melbourne service — and all will feature the Crystal suite from delivery.
The details: what Crystal actually delivers
The TCI Crystal suite is a staggered 1-2-1 configuration with a honeymoon option in alternating center rows. Regulatory filings and direct product documentation confirm a 23-inch seat width, a 22-inch IFE screen, sliding privacy doors, USB-C ports, wireless charging pads, noise-canceling audio jacks, and adjustable mirrors. The seat pitches at just 44 inches — efficient for a flagship product — and converts to a fully lie-flat bed. Every seat has direct aisle access, which the majority of Turkish Airlines‘ current widebody configurations do not offer.
The retrofit program on Boeing 777-300ERs runs approximately one week per aircraft, with work beginning in early 2025. Line-fitting on A350-1000s starts in late 2026, with Airbus confirmed to begin factory-installing the seat from 2028 onward. Some 777-300ERs will be retrofitted while others are retired as the fleet modernizes.
Detailed specifications confirmed by industry sources are below.
| Seat product | Aircraft | Privacy door | Screen size | Direct aisle access |

| Collins Aerospace Horizon | A350-900 (4 aircraft, ex-Aeroflot) | Yes — sliding door | 18 inches | Yes |
| Stelia Symphony | A350-900, Boeing 787-9 (57 aircraft) | No | 18 inches | Partial (alternating) |

Why building in-house changes the competitive equation
The strategic dimension of this announcement is the one most likely to be underestimated. Turkish Airlines is not simply installing a new seat — it is removing itself from the supply-chain bottleneck that has delayed premium cabin rollouts at carriers worldwide. Safran, Collins Aerospace, and Stelia (now Airbus Atlantic) all face multi-year backlogs; the retrofit delays affecting United Airlines‘ Polaris and British Airways‘ Club Suite programs are well-documented consequences of that constraint.
By developing Crystal through TCI Aircraft Interiors, Turkish Airlines controls production scheduling, customization decisions, and retrofit pacing. That independence matters enormously when the airline is targeting 560 aircraft by year-end 2026 and 800 aircraft by 2033. Air Traveler Club’s analysis of British Airways’ A380 premium cabin expansion illustrates precisely how retrofit timelines slip when carriers depend on third-party manufacturers — a risk Turkish Airlines has now structurally reduced.
The ultra-long-haul angle sharpens the value proposition further. Eight of the fifteen incoming A350-1000s will carry 60 to 66 business class seats in a ULR configuration targeting nonstop Istanbul–Sydney — a route where Qatar Airways, Emirates, and Etihad all require a connection. On that corridor, Turkish Airlines won’t just be competing on seat specs; it will be the only carrier offering a one-stop-free option.
How to target Crystal suite availability before the crowd does
The retrofit and delivery timeline creates a specific booking window that rewards early action — particularly for those planning travel on routes where the new seat will debut first.
- Target A350-1000 deliveries starting July 2026: The first A350-1000 arrives this month. If Crystal suites are confirmed on delivery, Istanbul–Sydney service (flight numbers TK168/TK169) becomes the highest-priority booking for suite access. Check the aircraft type at booking and verify via SeatGuru before confirming.
- Avoid older 777-300ERs until retrofit confirmation: Not all Boeing 777-300ERs will be retrofitted — some will be retired. Until Turkish Airlines publishes a confirmed retrofit list, treat 777 bookings as Safran Aura (no door, no direct aisle access) unless the seatmap shows a 1-2-1 configuration.
- Premium economy opens on 2028 A350 deliveries: The TCI Royalux seat — marketed as a widebody premium economy product with a 15.6-inch screen, privacy wings, and up to 10 inches of recline — debuts on new A350 deliveries from 2028. This cabin will also appear on the incoming batch of 35 Boeing 787s arriving from 2029.
- Miles bookings via Miles&Smiles: Turkish Airlines‘ own Miles&Smiles program remains the most direct path to award space on new routes. Star Alliance partner programs offer alternative redemption paths, but availability on newly launched ultra-long-haul routes historically tightens within weeks of schedule publication.
Watch for Turkish Airlines‘ official seat configuration announcement on the July 2026 A350-1000 delivery — that confirmation will trigger the opening of IST-SYD bookings and set the competitive tone for the Australia corridor through 2027.
FAQ
When will Turkish Airlines’ Crystal suite actually be available to book?
The first A350-1000 delivery is scheduled for July 2026. If Crystal suites are line-fitted on that aircraft — which TCI Aircraft Interiors has confirmed as the target — bookings on Istanbul–Sydney (TK168/TK169) could open with suite access by Q4 2026. Boeing 777-300ER retrofits began in early 2025, so some 777 routes may already feature the new seat; verify via SeatGuru before booking.
How does the Crystal suite differ from what Turkish Airlines currently offers on the 787-9?
The Boeing 787-9 currently features the Stelia Symphony seat — no privacy door, an 18-inch IFE screen, and only partial direct aisle access in alternating rows. The TCI Crystal suite adds a sliding privacy door, upgrades the screen to 22 inches, widens the seat to 23 inches, and adds wireless charging. The 787-9 fleet is not in the first wave of Crystal installations; the seat debuts on A350-1000s and retrofitted 777-300ERs first.
Will Turkish Airlines’ premium economy return on existing aircraft or only new deliveries?
Premium economy via the TCI Royalux seat will debut exclusively on new A350 deliveries starting in 2028. The initial 2027 aircraft with Crystal business class suites will not carry a premium economy cabin. Retrofitted 777-300ERs and the incoming 35 Boeing 787s arriving from 2029 are expected to include the cabin, but no confirmed retrofit schedule for existing 787-9s has been announced.
