How this map was built

Current fleet-linked numbered native map independently viewed. Boeing 777-300ER 4F/48J/28W/184Y: exact Premium Economy 34DEFG; Economy 48ACHK,61ACDEGHK and 62HK. Published cabin product dimensions are specification evidence only; per-seat unshown hardware, per-tail assignment and future retrofit geometry are not certified. Fleet counts retain their historical dated as-of values. October 6 methodology review: every seat evaluated within its own sold cabin. Sourced physical drawbacks cap at Be Aware; qualified service/bassinet cautions also prevent an unqualified upgrade. Extra Legroom is physical leg-space evidence, not a fee-based promotion. Exit eligibility, Forward Zone fees and ordinary positions remain neutral. All unmarked outboard window alignment is unknown; engineering overlays are disabled. No fixed-armrest, tray mechanism, reduced width, cold-air, recline exception or permanent storage loss is inferred from generic bulkhead/exit position. Unverified prior storage flags are withdrawn. Native furniture is schematic; no precise clearance/noise claim, no automatic Avoid from correlated service cautions. Product dimensions and historical retrofit announcements do not establish an unshown successor layout. Row 31 outboard31A/C/H/K are native Extra Legroom positions directly aft of paired Door 3 exits; airline emergency-exit eligibility and specific-flight assignment apply neutrally. Centre31DEFG have no numbered emergency-seat eligibility evidence; the generic whole-row exit_row attribute is removed. Row 49 outboard native Extra Legroom positions are adjacent to exits; centre49D/E/G have no numbered emergency-seat eligibility evidence;49D/G separately retain qualified bassinet cautions. Specific-flight booking restrictions control actual assignment. Historical official-23 is a superseded278-seat777-300ER diagram, retained only as a comparison exclusion; it does not define this current264-seat grid or any current seat rating. Native missing row48 centre band is blank before the labelled galley after that row; no service caution is inferred through this uncalibrated gap.

What changed

  1. Oct 6, 2026Exact native map and substantive within-cabin seat assessment; source-specific warning caps, unknown window limits, individual furniture symbols and unsupported storage/adjacency claims corrected.
  2. Jul 14, 2026Initial Singapore Airlines 777-300ER current 264-seat configuration, transcribed row-by-row from the linked official seat-map PDF; excluded the superseded 278-seat official map and unannounced 777-300ER retrofit target.
