Lufthansa Boeing 787-9 seat map — 287 seats

Lufthansa Boeing 787-9 with the Allegris long-haul cabin: 28 Business / 28 Premium Economy / 231 Economy = 287. Rolling out on newer Lufthansa 787-9 deliveries and progressively replacing the legacy 26/21/247 config (lh-789-26-21-247). Transcribed ROW-BY-ROW from the Lufthansa fleet seat-map PDF 202508_B789_Allegris_28C28W231Y.pdf (header "Lufthansa Boeing 787-9 Allegris (28 Business/28 Premium Economy/231 Economy)"; the PDF states the layout is "representative" and "deviations are possible"). No First Class on the 787-9. BUSINESS is the Allegris staggered 1-2-1 with five seat variants, rows 1-9 (columns A,C window-side / D,E,F,G centre / H,K window-side): row 1 = front-row Suites (1A,1D,1G,1K); window "Privacy" seats set into the window = A/K in rows 2,4,6,8; window "Extra Long Bed" seats set back from the window = C/H in rows 3,5,7,9; centre solo "Extra Space" seats = 2E,4F,6E; centre "Classic" pairs = D/G in rows 3,5,7; the cabin tapers so row 8 = 8A/8K and row 9 = 9H = 28 seats. The per-seat variant assignment is a STRUCTURAL INFERENCE (seatTypeInferred:true) from the Allegris product pattern and the A350 Allegris map convention, because the PDF prints seat/row identifiers but no per-seat product key. BLOCKED SEATS: the three row-2 Business seats (2A, 2E, 2K) are installed but NOT bookable pending seat certification — 25 of 28 Business seats are sold (Lufthansa Group newsroom; first flight with seats available took off 2026-03-15) — modelled bookable:false + unsellableReason "uncertified"; sellableSeats = 284. PREMIUM ECONOMY 2-3-2 rows 10-14 (row 13 skipped) = 28; row 10 is the bulkhead behind Door 2, extra-legroom with a centre bassinet. ECONOMY 3-3-3 rows 15-42 = 231: extra-legroom "Sitze mit mehr Beinfreiheit" (N tier, surcharge) seats = rows 15,16,18 (full rows, row 15 the bulkhead behind Premium Economy), the centre triple (D/E/G) of rows 19,20,21, and the window/aisle seats (A/B/C and H/J/K) of the Door 3 exit row 27 = 42 seats; the row-27 centre triple (D/E/G) is a bulkhead behind the mid-cabin lavatories (regular Y). The Door 3 lavatory complex sits between rows 26 and 27 WITHOUT removing seats (rows 15-26 are all full 3-3-3, unlike the legacy config). Tail taper: row 40 is full 3-3-3; rows 41-42 are the centre triple (D/E/G) only. COUNT: enumerated seats total exactly 287 (28+28+231) reconciling to the PDF title, so layoutProvenance = published_map. DERIVATIONS/UNPUBLISHED: the PDF publishes row/seat identifiers, cabin classes/counts, extra-legroom and bassinet markers, exits, galleys and lavatories, but NO numeric pitch/width/recline/bed lengths and no screen sizes — Business variant descriptions/dimensions follow the Lufthansa Allegris product pages (the Extra Long Bed 2.20 m figure is sourced; other bed lengths are estimates) and Economy/Premium Economy dimensions are unsourced estimates. windowAlignment left "unknown" for window seats. Engines 2x GE GEnx-1B74/75 per the PDF.
