Sơ đồ chỗ ngồi LATAM Airlines Boeing 787-9

LATAM Boeing 787-9 in its retrofit (2025-2026) cabin: 30 RECARO R7 Premium Business suites + 57 LATAM+ (extra-legroom Economy) + 216 standard Economy = 303. The per-cabin split (30 / 57 / 216 / 303) is the second of the two 787-9 rows in the Wikipedia LATAM fleet table (class columns J=Premium Business, W=LATAM+, Y=Economy). The R7 hardware — 30 suites on the 787-9, sliding suite doors, lie-flat beds, direct aisle access for every suite, a honeymoon-divorce staggered 1-2-1 layout, and USB-A + USB-C charging — is from RECARO Aircraft Seating (the seat manufacturer). This config REPLACES la-789-313; as of early 2026 ~2 of 14 in-scope 787-9s were converted (RECARO retrofit program = 24 shipsets: 20 R7 per 787-8 x10 + 30 R7 per 787-9 x14), with completion targeted H2 2026, so both configs fly concurrently. LATAM+ MODELLING (AUTHORING sec.6): LATAM markets it as "Premium Economy" on latamairlines.com, but the currently-flying product is extra-legroom Economy in the same 3-3-3 layout (same seat, more pitch) — the genuine wider-seat premium economy, "Premium Comfort" (RECARO PL3530), is a separate FUTURE product with installations from 2027 and is NOT modelled here. LATAM+ is therefore modelled as a location/legroom-priced ZONE inside the single Economy cabin (canonicalTier extra_legroom_economy, cabinSummary code N), not a fake standalone cabin. THE ROW GRID IS DERIVED: latamairlines.com is bot-hostile (403/blocked) and competitor seat-map sites are prohibited, so no airline-published map was captured. Business 30 = derived bulkhead row 1 (two window suites) + rows 2-8 (7x4 = 28). Economy 273 = rows 11-41 of 3-3-3. LATAM+ 57 = rows 11-16 (54) + a derived 3-seat centre stub at row 17 in the over-wing (Door 3) vestibule (reconciling 54 + 3 = 57); the over-wing exit row (row 18) also offers extra legroom but is counted as standard Economy to reconcile the sourced 57. Standard Economy 216 = rows 18-41 (24 x 9). Row/exit/furniture placement is constructed to reproduce the neutral-sourced totals and may differ from the airframe. NO pitch/width/recline or screen sizes are published by LATAM (site blocked); all seat-type dimensions are flagged unsourced and screen sizes omitted. windowAlignment is "unknown" for window seats (a derived grid cannot prove alignment).
