Sơ đồ chỗ ngồi easyJet Airbus A321neo

Single-class, 3-3 economy. 'Up Front' (rows 2-6) and 'Extra Legroom' are a-la-carte seat-selection tiers WITHIN the one economy cabin, not separate cabins. Up Front is a LOCATION-ONLY tier: identical slimline hardware and legroom to standard economy, sold for the forward position / faster boarding. Modelled with the 'standard' seat type plus preferred_zone + paid_seat flags (no extra_legroom flag). Extra Legroom = row 1 bulkhead + the emergency-exit rows; modelled as extra_legroom seat types. PITCH VARIES BY ROW inside the single cabin. easyJet publishes only a MINIMUM pitch of 28in and MINIMUM width of 16in. Rear rows (31-40) use the 28in minimum (sourced); mid-cabin 29in and exit-row ~35in are estimates (unsourced:true). Two mechanisms used: (a) seat-type variants for the discrete bands (standard 29in, standard-rear 28in, extra-legroom 35in); (b) per-seat dimensionOverrides to differentiate row 18 (33in) from row 19 (35in) within the same extra-legroom type. Seat count 235 reached with 38 full 3-3 rows plus rear taper: row 39 = 4 seats (E,F removed) and row 40 = 3 seats (D,E,F removed) for the two rear-right lavatories. Exact per-row seat presence and the exact row numbers of the exits/lavatories are STRUCTURAL INFERENCE (unsourced) derived from the ACF door arrangement and the 235 total; easyJet does not publish a public LOPA. ACF exit arrangement (Airbus, Wikipedia): forward Door 1, two pairs of Type III+ over-wing exits replacing the old L2/R2 doors (modelled at rows 18-19), and Door 3 relocated further aft (modelled at row 30). Recline modelled as 'none' (fixed-back slimline) — characteristic of the hardware, not published by easyJet. Amenities modelled as absent: no seatback/overhead IFE, no in-seat power, no Wi-Fi; buy-on-board cafe only. No data was taken from competitor seat-map sites; row numbers were derived from ACF geometry, not copied.
