China Eastern Airlines Boeing 777-300ER — mapa de assentos

Three-class China Eastern Boeing 777-300ER, the flagship it introduced on 26 September 2014. PER-CABIN COUNTS ARE SOURCED from the Wikipedia China Eastern fleet table (neutral backbone): 20 in service, 6 First / 52 Business / 258 Economy = 316 (the count cells carry a "citation needed" tag but are the only neutral per-cabin figures and are corroborated by the airline product prose). CABIN PRODUCTS ARE SOURCED: Wikipedia states First on the 777s is a fully-flat seat with direct aisle access and a sliding door, that "middle seats on the Boeing 777s can be turned into a double bed", Business on the 777s is the Zodiac Cirrus seat, and the 777s have seat-back entertainment and complimentary meals; China Eastern's own press release "New China Eastern Airlines Plane-Boeing 777-300ER" (primary) independently describes "private first-class cabins with romantic double beds", "comfortable business class where passengers can lie down", "compact economy class", and Wi-Fi, and a second ceair.com press release confirms free on-board Wi-Fi on the B777-300ER. LAYOUT IS DERIVED_FROM_COUNTS: no airline seat map/schematic was retrievable (the ceair.com fleet page renders its diagram as an image absent from the Wayback Machine), so the row grid, cabin boundaries, door/exit positions and monuments are structural reconstructions from the published counts + standard 777-300ER geometry; every cabin carries derived:true. DERIVATIONS: First is modelled 1-2-1 across rows 1-2 with the four centre suites (1D/1G/2D/2G) as the convertible "double bed" pairs — row 1 full (A,D,G,K = 4) and row 2 the centre pair only (D,G = 2) = 6; window suites appear only in row 1. Business is the Zodiac Cirrus reverse-herringbone 1-2-1, rows 11-23 (13 x 4 = 52), every seat with direct aisle access. Economy is 3-3-3 nine-abreast (rows 31-59): the low 258-seat Economy count on a 777-300ER — far below the 350-400+ of a high-density 3-4-3 jet — is consistent with the 9-abreast layout China Eastern's Chinese widebody peers use, so 3-3-3 is adopted (bulkhead row 31 extra-legroom, standard rows 32-43, a limited-recline row 44 ahead of two over-wing exit rows 45-46, standard rows 47-58, and a six-seat last row 59 with the centre triple removed at the aft galley) = 9 + 108 + 9 + 9 + 9 + 108 + 6 = 258. Exit/door and galley/lavatory positions are derived (not published). No seat pitch, width or IFE screen size is published by China Eastern for this aircraft, so those numbers are omitted rather than estimated. windowAlignment is left "unknown" on all window seats because the grid is derived (there is no 777 window grid). Per-tail confirmation that all 20 airframes share this single layout is not published, but China Eastern markets only the one 777-300ER configuration.
