LATAM Airlines Boeing 787-9 seat map

LATAM Boeing 787-9 in its pre-retrofit (legacy) cabin: 30 Business (lie-flat) + 283 Economy = 313. The per-cabin split (30 / – / 283 / 313) is the first of the two 787-9 rows in the Wikipedia LATAM fleet table (class columns headed J=Premium Business, W=LATAM+, Y=Economy; the legacy row shows no LATAM+ seats). This config is a RETROFIT SOURCE: from 2025 LATAM is converting its 787s to RECARO R7 Premium Business suites plus a LATAM+ extra-legroom zone (successor config la-789-303); as of early 2026 only ~2 of 14 in-scope 787-9s were converted, with completion targeted for H2 2026, so the legacy layout was still the majority of the 28-strong 787-9 fleet at capture. THE ROW GRID IS DERIVED, not a placard scan: latamairlines.com is bot-hostile (direct fetch returns 403/blocked) and competitor seat-map sites are prohibited, so no airline-published 787-9 map could be captured. Business is modelled as the standard legacy LATAM 787 lie-flat product in 2-2-2 (5 rows x 6 = 30); the 2-2-2 abreast and the row grid are UNSOURCED from any citable primary/neutral page (see caveat) — the count of 30 is neutral-sourced, the layout is derived. Economy 283 = rows 11-42 (32 rows of 3-3-3, 288) minus two derived reductions: row 27 loses the right triple to the over-wing (Door 3) galley/lav complex (-3) and row 42 tail-tapers to seven abreast (-2). Exit-row placement (row 28, over-wing), the over-wing band, bulkhead and furniture were constructed to reproduce the neutral-sourced totals and may differ from the actual airframe. NO pitch/width/recline or screen sizes are published by LATAM for these cabins (site blocked); all seat-type dimensions are flagged unsourced and screen sizes omitted. windowAlignment is left "unknown" for window seats (a derived grid cannot prove window-to-seat alignment).
