Sơ đồ chỗ ngồi Delta Air Lines Airbus A321ceo

PUBLISHED (delta.com A321-200 page): per-cabin seat counts (Delta First 20, Delta Comfort 35, Delta Main 136 = 191), seat width/pitch, movable-armrest locations, exit/galley/lavatory totals (8 exits, 4 galleys, 4 lavatories) and per-cabin amenities (Wi-Fi, USB in-seat power, in-seat AC power outlet, personal video, satellite TV). PUBLISHED (official Delta LOPA seat-map image, A321-200-DOM-321): the full row grid read row-by-row — Delta First 2-2 on columns A/B|C/D (rows 1-5), Delta Comfort 3-3 (rows 10-15) and Delta Main 3-3 (rows 16-39), the two over-wing exit-door pairs, the mid-cabin and aft monuments, and every removed/reduced seat. Removed seats verified against the published counts: 13D (fwd over-wing exit passage) -> Comfort 35; 25A/B/C (mid-cabin lavatory), 26C/26D (aft over-wing exit passage) and 39D/E/F (aft galley) -> Main 136. Row numbering follows the LOPA exactly (First 1-5, a gap, Comfort 10-15, Main 16-39). INFERRED: over-wing exit-row seats (Comfort row 13; Main row 26) are modeled as extra-legroom Delta Preferred seats with the standard evacuation restrictions (no infants / unaccompanied minors). The LOPA does not print per-seat recline limits, so no no_recline/limited_recline is asserted on the exit rows; only the last row (39), which backs onto the aft galley/lavatories, is marked limited_recline. The wing silhouette on the LOPA spans roughly rows 13-26 (between the two over-wing exit doors); those rows carry over_wing and window seats note the wing view. windowAlignment is left 'unknown' on all window seats — the LOPA does not show the window belt line. aircraft.windowGridType is intentionally omitted: no a321ceo grid exists in data/window-grids/, and the a321neo grid describes Airbus Cabin Flex (ACF) door geometry (two Type III+ over-wing exits) that does NOT match the classic A321ceo, which uses four full passenger/emergency door pairs (Doors 1-4) at different fuselage stations. The Airbus A320-family grids carry no structural window blanks, so binding a grid would not change any windowAlignment value; the classifier was not run. Delta First columns are lettered A/B|C/D (2-2) per the LOPA, while Delta Comfort and Delta Main use A-F (3-3); window seats are A/D in First and A/F in the 3-3 cabins.
