Sơ đồ chỗ ngồi Southwest Airlines Boeing 737 MAX 8

Southwest's first assigned-seating cabin. Single Economy class sold in three LOCATION tiers, not three hardware classes: Extra Legroom (~34" pitch, genuine extra pitch), Preferred (~31", same hardware as Standard, priced for its forward location) and Standard (~31"). Modeled as ONE economy cabin (canonicalTier 'economy'). The Extra Legroom pitch difference is captured with a distinct seatType (category extra_legroom) applied via per-seat seatTypeId override; Preferred is captured purely with the preferred_zone + paid_seat flags because its hardware is identical to Standard. See the schema-feedback section of the report for why separate cabins were rejected. Tier ROW ZONES (front rows Extra Legroom; rows around the mid-cabin exits Extra Legroom; rows between them Preferred; rear rows Standard) follow southwest.com wording and travel-press analysis. Zones used: EL front rows 1-5; Preferred rows 6-12; EL exit rows 13-15 (14 & 15 are the over-wing exit rows); Standard rows 16-30. DERIVATION: Southwest does not publish an exact per-row seat map or exact pitch for the MAX 8. 175 seats cannot fill a pure 3-3 grid (175 = 6*29 + 1), so the two aft-most rows (29, 30) are modeled as narrowed by the rear galley/lavatory monument (row 29 = 4 seats, row 30 = 3 seats). The precise location of the removed seats is a structural inference, not a Southwest-published fact. Pitch values (34" Extra Legroom, 31" Standard/Preferred) are reported by travel press and marked approximate; Southwest publishes only 'up to five additional inches' (on the 737-700) and 'seat pitch will vary by aircraft type'. Seat width and recline are unpublished estimates (unsourced). In-seat USB-A/USB-C power is standard on 737 MAX 8 airframes delivered from October 2025 and on retrofit airframes; older un-retrofitted airframes may lack it.
