Turkish Airlines Airbus A350-900 koltuk haritası

The current-fleet source lists Turkish Airlines' active 316-seat A350 as 28 Business / 288 Economy and identifies the subfleet as orders taken over from Aeroflot. Airbus documents the inherited as-delivered cabin as 28 private full-flat Business suites + 24 extra-legroom Comfort + 264 Economy = 316. Turkish does not sell Premium Economy on the cited current configuration, so the former 24-seat Comfort block is modeled as a separate physical Economy section with canonicalTier economy and cabinGroupId economy; its extra-legroom hardware does not create a W or N sold tier. Those 24 seats are rated standard as the baseline within their physical subcabin, while the sourced extra_legroom flag preserves their advantage over the main Economy hardware. No permitted source located publishes the current Turkish row map. The grid is DERIVED: seven 1-2-1 Business rows (7 x 4 = 28), three 2-4-2 former-Comfort rows (3 x 8 = 24), and twenty-nine full 3-3-3 rows plus a three-seat tail row (29 x 9 + 3 = 264). Row 13 is omitted solely as a representational convention. All row numbers, columns, boundaries, stagger, and taper placement are inferences. Monuments, exits, wing limits, bassinets, dimensions, exact window alignment, and a current Turkish fee zone for the former Comfort seats are intentionally not asserted.
