Mapa de asientos del Boeing 737-900ER de Sun Country Airlines

The current official aircraft table publishes one 186-seat, 3–3 passenger configuration for the 737-900ER. The June 30, 2026 fleet table reports three passenger 737-900ER aircraft; fleetCount is that dated type-level count, not a September tail-by-tail confirmation. This representative map is generated only from the published capacity and abreast layout. Rows 1–31 are synthetic numbering for 31 complete six-seat rows; actual row numbers and any partial rows remain unknown. Best, Standard and Exit Row product counts and locations are unresolved, so all seats have neutral ratings and no product benefits assigned. No exits, monuments, wing positions or seat dimensions are inferred. The official aircraft-wide ranges are 31–34 inches ordinary pitch and 16.3–17.3 inches width, with 39-inch exit pitch; these are recorded here only and are not individual seat measurements. The unbound SY111 186-seat selector is not attributed to this subtype. Sun Country continues independent operations during Allegiant integration. Cargo aircraft are excluded. Independent review dated 2026-10-01: the retained SY brand identity is an editorial indexing choice. Acquisition/fleet claims here use a condensed primary-source extraction; full release wording is not available in this snapshot. No type-unbound selector or product map is transplanted.
