Thai Airways International Boeing 787-9 seat map — 298 seats

Official THAI 789 native diagram transcribed by exact numbered seat positions, including partial rows and skipped numbering. Every seat evaluated within its sold cabin; ordinary position, premium cabin amenities, preferred-selection charges and exit eligibility are not comfort upgrades. Native service-bank cautions are categorical, qualified and unmeasured; no inference across doors, nearer unknown blocks or uncalibrated gaps. No diagram window-alignment warning is present: outboard seats remain unknown; engineering overlays disabled. No row-specific pitch, recline limitation, fixed-armrest width loss, cold-door effect or storage restriction is inferred. Numeric dimensions and hardware are withheld where the current specification table cannot be linked consistently to this exact native drawing; source ledger retains specifications separately. Individually identified native service banks are reviewed on both sides. Only the nearest occupied chair block without an intervening door, occupied chair row or nearer unidentified block receives a qualified caution. Skipped row numbers do not imply a physical empty row. The native bank ledger records inclusions and exclusions; furniture anchors do not certify their physical ordering. The native chart labels exit doors but provides no seat-specific legend identifying regulated exit seats. General airline exit eligibility is disclosed at source/config level; exact restricted-seat assignments require airline confirmation and are not invented from door proximity or zone colours.
