Sơ đồ chỗ ngồi Lufthansa Airbus A350-900

Lufthansa pre-Allegris high-density A350-900 long-haul cabin: staggered 1-2-1 Business (rows 1-8), 2-4-2 Premium Economy and 3-3-3 Economy. The PDF legend states this is NOT the majority A350 configuration (deviations possible). Structure transcribed from the Lufthansa fleet PDF 202603_A359_30-26-262.pdf (rev 2026-03). CABIN STRUCTURE (read from the map): Business staggered 1-2-1 (window singles A/K, centre pair D/G) rows 1-8; Premium Economy 2-4-2 rows 10-12; Economy 3-3-3 with the extra-legroom symbol on the row behind Premium Economy (row 14) and the mid-cabin exit row aft of Door 3 (row 30, centre bassinet), a Preferred Zone across the forward Economy rows (15,16,18,19,20), and a fuselage-tapered tail. TITLE vs DRAWING RECONCILIATION (AUTHORING §5b): the PDF title states 30 Business / 26 Premium Economy / 262 Economy (318 total); the compressed row drawing renders a couple more Business seats (~row 8) and a couple fewer clearly-resolvable Premium Economy seats than the title, and the aft Economy taper is ambiguous. The explicit numeric title counts are authoritative, so each cabin grid is reconciled to the title: Business = 30 by modelling the rear row 8 as the centre pair only; Premium Economy = 26 by modelling a bulkhead window pair at row 9 ahead of the three full 2-4-2 rows; Economy = 262 by modelling the tapered rows 44 (7 seats, window A/K absent) and 45 (3 centre seats). Hence layoutProvenance = mixed. Extra-legroom (N) = rows 14 and 30 (18 seats); everything else in Economy is Y. Row 13, 17, 29 are unused (skipped). DERIVATIONS / UNPUBLISHED: the PDF publishes row/seat identifiers, cabin classes and counts, extra-legroom and Preferred-Zone markers, bassinet/family positions, exits, galleys and lavatories (incl. accessible), but NO numeric pitch/width and no amenity detail — all pitch/width/recline/bed values are unsourced estimates, the regular Economy pitch itself is unpublished, and the extra-legroom delta is shown by symbol only. windowAlignment is left unknown for window seats (A/K). Screen sizes are not shown and are omitted. Wing extent is approximate. Amenities are the Lufthansa long-haul product described from Lufthansa product pages, not this PDF.
