    Exit-seat occupants must be at least 12 years old whether accompanied or not, and not seated with an infant. Advance seat-reservation limitations for unaccompanied minors are separate from exit occupancy eligibility. Extra-legroom seats can be reserved for an additional fee by passengers not eligible for free reservation; Cathay Diamond/Gold, oneworld Emerald/Sapphire and Economy Flex passengers can reserve them free.

    Applied only to individually native-marked exit seats. No blanket unaccompanied-minor occupancy prohibition is inferred from advance-reservation policy; no quality effect. Retained paid_seat flags apply only to individually source-marked extra-legroom seats and indicate conditional reservation fees, not a universal charge or quoted price; fare, status and booking conditions determine fees.

How this map was built

Cathay's current official 77K native seating plan supplies numbered rows, seat letters, partial rows and the published 368-seat layout. Individual native legend glyphs: emergency exit only 59A, 59K; emergency exit with extra legroom 43A, 43B, 43C, 43H, 43J, 43K, 59B, 59C, 59H, 59J; extra legroom without exit designation 40C, 40H. Plain exit glyphs establish eligibility alone. No family-wide or row-position assumption fills unmarked seats. Eligibility remains neutral; ordinary window alignment and as-flown assignment remain unknown. Methodology assessment 2026-10-05: each bookable seat reviewed within its own cabin against the current official seat plan and published exceptions. Cabin amenities and seat-selection eligibility do not create a quality upgrade. Standard denotes the reviewed cabin baseline, with unresolved physical details explicitly retained. G/L flags identify only inspected nearest labelled schematic boundaries and remain capped BeAware; unlabelled blocks, intervening structures and uncalibrated gaps do not establish physical proximity. Every expressly icon-labelled galley/lavatory block is transcribed using its native transverse bank and a qualified derived row anchor. Furniture rendering remains a coarse schematic; unlabelled blocks and overlapping anchors do not certify exact footprint or distance. The 77K-to-77J retrofit linkage and lifecycle fields are inferred from the annual report retrofit programme and both diagrams being published; Cathay does not explicitly identify this configuration-code-to-code mapping.

What changed

  1. Oct 5, 2026Rechecked official native rows and cabin totals; preserved historical ID and seat grid. Assessed every seat relative to its cabin and retained unknown physical details. Transcribed labelled service icons with qualified bank/row anchors and documented cautious service exposure or explicit exclusions. Rechecked individual exit and extra-legroom glyphs. Cited current airline exit eligibility policy: minimum age 12 and no infant; removed unsupported blanket unaccompanied-minor occupancy restrictions. Eligibility remains separate from comfort quality. Withdrew unsupported extra-legroom flags/types on 59A, 59K. Removed unsupported cold_by_door penalties. Corrected native bassinet bank/row provenance without a comfort penalty.
  2. Jul 14, 2026Initial Cathay Pacific 77K Boeing 777-300ER configuration from Cathay's live fleet page and official 2026 seating-plan image.
