2026-09-30: Replaced the earlier count-derived synthetic grid with United's archived official map. Business1-12; Premium Plus20-22; Economy/Economy Plus30-35 and42-57. Row42 and43 contain side triples only; row56 and57 use2-3-2 rear taper. Mixed blue/white rows preserve the actual product assignment instead of treating Economy Plus as an invented contiguous cabin. Economy Plus is a zone in the shared economy cabin. Standard dimensions verified against the matching version. All physical window alignments remain unknown. Monument inventory omitted pending complete transcription; no unsourced adjacency flags survive the old synthetic grid. Legacy hardware/amenity claims and tail/fleet assignments remain partial. The earlier asserted January 2026 effective date and conversion/retrofit lineage are not established: United describes the Elevated aircraft as new deliveries. Both configurations remain available; no legacy airframes are silently retired. Published matching-version fixed-bassinet assignments: United Polaris® business class: 1A, 1L; United® Premium Plus: 20C, 20DEF, 20J; United Economy Plus®: 30C, 30DEF, 30J, 44DEF; United Economy®: No. These table assignments are documented here; per-seat adjacency warnings and full-row eligibility are not inferred. Any source letter/product conflicts retain their existing unresolved status.
O que mudou
- 1 de out. de 2026Independent United source triage: version-bound power/USB/IFE, zero recline, exact staggered MAX8 labels and published exceptions, source-date/product wording qualification. Legacy inferred hardware, furniture and window uncertainty remain explicit. Qualify United outlet connector claims: generic availability remains prose, unsupported AC enum omitted, explicit wireless/StudioUSB-C preserved. No map, numbering, totals, coordinates or source archives changed.
- 30 de set. de 2026Primary-source audit: updated published standard dimensions; reconstructed grid only where explicit archived airline image reconciliation is implemented. Remaining unverified scope documented in notes.
- 14 de jul. de 2026Initial legacy United 787-9 (257-seat) four-cabin config; per-cabin split from Wikipedia fleet table, Polaris/Premium Plus specs from United product releases, row grid derived from published layouts and totals. Linked as retrofit_source to ua-789-222.
