Vietnam Airlines Airbus A321ceo koltuk planı — 178 koltuk

Vietnam Airlines' current A321 page embeds this official A321-1 map, which supplies the exact published row grid, cabin boundary, doors and monuments; layoutProvenance is published_map and no cabin or row is reconstructed from counts. Business is full 2-2 in rows 1-4 (16); Economy uses rows 10-12 and 14-38, with row 14 A/B/C/E/G; row 27 A/B/C/E/G; row 38 E/G; the enumerated total is 16J/162Y=178. The same carrier page labels Economy rows 10-12 as Premium Economy on domestic operation but as Economy on international operation. Because this is a route-dependent service overlay on the same 3-3 seats rather than a stable physical configuration, the seats remain in one Economy cabin and count as Y; no fixed Premium Economy cabin is invented. Emergency-exit rows 14 and 27 are flagged extra-legroom because Vietnam Airlines sells emergency-exit-row positions as wide/extra-legroom seats; exact row placement comes from the published doors. No a321ceo engineering grid exists under data/window-grids at generation time (the shorter a320ceo and ACF a321neo grids are not substitutes), so windowGridType is omitted and window-position alignments remain unknown. The neutral fleet table duplicates the 8J/195Y=203 split under A321-200 and A321neo, but Vietnam Airlines explicitly identifies 8J/195Y as its A321neo configuration; no separate ceo-203 file is fabricated. October 6 assessment: every bookable seat independently evaluated within its own cabin against the exact numbered native map, published product, marked bassinet/exit evidence and nearest contiguous labelled service bank. Standard is a reviewed baseline; cabin-wide pitch/flat-bed/IFE benefits and selection fees do not justify Good. No window positions, seat-specific recline restrictions, armrest/tray geometry or door temperature measurements are published: outboard alignment remains unknown, and no warnings or glyphs are inherited from another variant. Service cautions are qualified possibilities, not measured noise; no inferred cold-door/recline/armrest/storage penalties. Service cautions are not extended across gaps whose separation is unverified.
