Sơ đồ chỗ ngồi Air France Airbus A220-300

PUBLISHED (Air France press releases "Air France unveils its first Airbus A220-300" and "…enters commercial service"): 148 seats in a 2-3 layout (5 abreast) giving ~80% of customers a window or aisle seat; the widest economy seat on the market at 48 cm (18.9 in); adjustable headrest, leather upholstery, a tray table, USB-A and fast USB-C (60 W) ports and a tablet/smartphone holder in the seatback; Air France Connect Wi-Fi; the largest windows in the class (~11 in wide x 16 in tall) and up to 20% more overhead stowage; and 3 lavatories (one forward reserved for Business, two in the aft galley). Two cabins — Business and Economy — are created with a MOVABLE curtain at the front of a single physical 2-3 deck; the Business block is sized by demand up to a maximum of ~23 seats (8 rows) with the two adjacent seats in each business row (columns C and E) kept free. PUBLISHED (Wikipedia, Air France fleet): 57 A220-300 in service, single-class 148-seat (all-Economy) configuration replacing the A318/A319. MODELING (AUTHORING.md 6): because the seats are identical Economy hardware and no fixed cabin boundary exists, this is ONE economy cabin (canonicalTier economy) with Business expressed as a demand-dependent ZONE (representative maximum rows 1-8); no seat is assigned a Business tier, so cabinSummary carries no J token and all 148 seats sell as Economy on a full-economy flight (nothing marked bookable:false). COLUMN LETTERING: Air France letters the 2-3 as A,C (pair) | D,E,F (triple), skipping B; this is what makes "seats C and E are not sold in Business" the two Euro-Business empty seats (aisle-of-pair C and middle-of-triple E), and yields the published 80% window/aisle share (A,C,D,F window/aisle; only E middle). DERIVED / no published Air France seat map: the row grid (rows 1-30), the single over-wing exit row (row 12, with the two window seats A and F removed for the exit passage per standard A220-300 door geometry), the wing extent (rows ~11-16, over_wing), the forward Door 1 / galley / Business-lavatory monuments, and the aft Door 2 / galley / two lavatories are reconstructed from A220-300 geometry and the golden A220 exemplar (dl-223-130), not read from an airline LOPA. Row 1 (bulkhead) and row 30 (last row, aft galley/lavatories) carry the usual bulkhead/rear-monument drawbacks. Seat pitch is not published by Air France and is an unsourced estimate; recline is published only as "reclines to 118 degrees" (kept in the seat description, not forced into a numeric recline-travel field). windowAlignment is "unknown" for every window seat: no A220 window-belt engineering grid exists and there is no published Air France map, so no full/partial/none is asserted. Exit-row seats have more legroom (flagged extra_legroom, rated good) but are NOT modeled as a separately-sold extra-legroom product (no Air France source brands an A220 extra-legroom fare), so they remain Economy (Y) rather than an N tier.
