China Airlines publishes one current 777-300ER seat-map entry and one linked B777-300ER chart, unlike the separately labeled A350 variants on the same index. Its current Operational Overview lists all 10 777-300ERs in service as of 2026-05-31, so one active configuration is modeled and no second flying variant was found. The official chart publishes 40 Premium Business, 62 Premium Economy and 256 Economy seats = 358. Business is full 1-2-1 rows 10-12, 14-16 and 20-23 (10x4=40). Premium Economy is full 2-4-2 rows 30-36 plus 37DEFG/HK (7x8+6=62). Economy is full row 40, full rows 41-43 and 45-53, 54AC/DEFG, 60ABC/HJK, full rows 61-69, and 70-72AC/DEFG/HK, totaling 256. The same chart also provides a two-cabin sale list in which Premium Economy hardware may be sold as Economy; installed hardware remains modeled as Premium Economy. China Airlines has ordered A350-1000 and 777-9 aircraft under a fleet plan whose deliveries begin from 2029. Its 2026 investor-presentation search extract keeps the 777-300ER fleet at 10 through end-2026 and says phase-out is only under evaluation from 2030, so this map remains active rather than retrofit_source. Paid Preferred/Extra Comfort labels alone do not prove a comfort advantage within the modeled cabin. Schematic proximity supports qualified Be Aware cautions, not calibrated distance or measured disturbance. CRS installation exceptions do not prove missing windows. No engineering window model is used. Extra Comfort remains a commercial selection name on the underlying Economy hardware. Its seat-type category and canonical tier remain Economy; paid_seat records its fare-dependent pricing category. There is no source-supported physical extra-legroom taxonomy. Official installed cabin totals are 40J/62W/256Y. Exact native G/L/accessible icons have each been transcribed separately. Their row anchors support schematic ordering, not literal footprint or distance. Closets and intervening service/lounge blocks are not inferred as lavatories or galleys. Ordinary unannotated window alignment remains unknown. The native diagram explicitly marks plugged windows 20A/K and 32A/K and solid no-window side walls 40A/K and 60A/K. Fixed-armrest outlines also mark 53B and 68B/J/69B/J. Row 40 lies after the Door 3 entrance while all labeled Door 3 lavatories lie before it; no lavatory warning crosses that entrance gap.
What changed
- Oct 5, 2026Root source review: replace historical relay caveat with correct fresh direct index provenance; retain historical access failures separately in audit ledger.
- Oct 5, 2026Actual Claude second-pass supported source/text corrections; reconcile Door3 entrance proximity where applicable and readable evidence caveats.
- Oct 5, 2026Actual Claude findings: reconstruct all labeled native service icons, reconcile exact nearest-seat cautions and armrest observations, remove unsupported mirrors and stale evidence metadata.
- Oct 5, 2026Root review: preserve Extra Comfort commercial names and type IDs, classify physical hardware as underlying Economy, recompute official cabin totals and retain fare-category information only.
- Oct 5, 2026Root review: replace unsupported fee-category extra_legroom claims with paid_seat and qualify Extra Comfort dimensional notes.
- Oct 5, 2026Independent official-diagram methodology assessment; corrected unsupported window inferences, physical drawback caps and categorical service-bank cautions.
- Jul 16, 2026Initial China Airlines 777-300ER 358-seat configuration transcribed from the current official published map.
