How this map was built

Fleet count (10) and per-class seat counts are from the Wikipedia LATAM Airlines Brasil fleet table (Global Airline Guide 2025), which lists the 777-300ER as 38 Premium Business (J) / 50 (W) / 322 Economy (Y) / 410 total. All 10 airframes are operated by LATAM Brasil and carry the retrofitted "Premium Business" cabin standard. MIDDLE-TIER RECLASSIFICATION: the Wikipedia table labels the 50-seat middle tier "Premium Economy (W)". LATAM does NOT operate a distinct premium-economy cabin on the 777 — these 50 seats are the extra-legroom "LATAM+" preferred seats at the front of the single economy cabin (ordinary economy seats sold with more legroom + priority boarding). Per AUTHORING §6 this is modeled as an extra_legroom_economy ZONE within the economy cabin (seatType latam-plus, canonicalTier extra_legroom_economy), not a separate cabin. Hence cabinSummary counts them as N, not W. ROW GRID IS DERIVED, not a placard scan: latamairlines.com is a bot-hostile JS-rendered SPA (raw/Wayback bytes contain only the page shell) and competitor seat-map sites are prohibited sources. Row numbers, the LATAM+ zone rows, exit-row placement, over-wing range, door/galley furniture, and the rear taper were constructed to reproduce the published per-class totals and the standard 777-300ER abreast layouts; they may differ from the actual aircraft placards. Premium Business: Thompson Aero Vantage XL, staggered 1-2-1 "honeymoon" layout with lie-flat beds and direct aisle access to every seat (Thompson Aero, Aug 2019). Derived as rows 1-9 full (36 seats) + a reduced rear row 10 of the two centre seats to reach the published 38. Economy is 10-abreast 3-4-3. The published 50-seat LATAM+ count equals exactly 5 rows x 10, modeled as the front five economy rows (11-15). Standard economy (322) = rows 16-46 full (310) + a tapered row 47 of 8 (window pairs removed, 2-4-2) + a 4-seat last row 48 = 322. Exit rows (30, 42) and over-wing rows (26-34) are derived positions for the 777-300ER five-door layout. Seat widths, pitch and screen sizes are not published in the cited primary/neutral sources; economy and LATAM+ pitch figures are unsourced estimates flagged as such, and no IFE screen dimensions are asserted.
