Southwest Airlines Boeing 737-700 seat map

Southwest's assigned-seating 737-700 cabin (bookable for travel from January 27, 2026). Single Economy class sold in three LOCATION tiers, not three hardware classes: Extra Legroom (~36" pitch on the 737-700 — 'five extra inches of seat pitch' per southwest.com), 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, canonicalTier extra_legroom_economy) applied via per-seat seatTypeId override, and Preferred is captured purely with preferred_zone + paid_seat flags because its hardware is identical to Standard (same modeling decision as the golden 737 MAX 8 file). SEAT COUNT: Southwest publishes no fleet-spec page and no per-row map. The current fleet total of 137 seats is from the Wikipedia Southwest Airlines fleet article (retrieved 2026-07-14); the previous OPEN-SEATING 737-700 carried 143 slimline seats. Under assigned seating the -700 loses roughly one row of six seats (143 -> 137): removing ~31" of cabin length funds the five extra inches added to the ~6 Extra Legroom rows, matching Southwest's statement that Extra Legroom on the -700 is achieved by creating extra pitch. DERIVATION (derived_from_counts): the 3-3 row grid, zone boundaries, and monument placement are structural inferences, not Southwest-published facts. 137 = 22 full 3-3 rows (132) + a narrowed aft row of five (row 23), the sixth seat displaced by the aft galley/lavatory. Tier ROW ZONES follow southwest.com wording ('Extra Legroom at the front of the cabin and near the exit rows'; 'Preferred: Standard legroom near the front of the cabin'; 'Standard: back of the cabin'): Extra Legroom = front rows 1-4 and the over-wing exit rows 11-12; Preferred = rows 5-10; Standard = rows 13-23. The 737-700 has a SINGLE over-wing exit pair (one exit per side) — unlike the 737-800/MAX 8's two pairs — so there is one exit row (row 12) plus the Extra Legroom row just ahead of it (row 11). PITCH: Standard/Preferred ~31" is travel-press approximate; the +5" Extra Legroom differential (=> ~36") is published by Southwest specifically for the 737-700. Seat width and recline are unpublished estimates (unsourced). POWER: the 737-700 is Southwest's oldest sub-fleet (deliveries 1997-2011, retiring by 2031); in-seat USB power exists only on retrofitted airframes and many -700s have no in-seat power at all; there are no AC outlets.
