Thai Airways International Boeing 777-300ER koltuk haritası

THAI's two-class 777-300ER (internal type code 77B), 14 aircraft, the airline's most common 777-300ER. All per-cabin counts and the seat grid are read from THAI's own published cabin map (ouraircraft-77B.png) and the thaiairways.com fleet page: Royal Silk 42 (staggered 1-2-1 Stelia Solstys, 41-46" pitch, 21" width, 180-degree flat 73.5" bed, 15.4" screen) and Economy 306 (3-3-3 Safran 5751, 31-32" pitch, 18.1" width, 10.6" screen). Royal Silk is split into two staggered cabins — Zone A rows 11,12,14,15,16,17 (24 seats, row 13 skipped) and Zone B rows 18-22 (18 seats; row 18 is a centre-pair-only partial where the single seats give way to closets). "Together" rows (centre pair together, single seats toward the aisle) use B/E/F/J; "apart" rows (centre seats split toward the aisles, single seats at the window) use A/D/G/K. Economy is three published zones matching the map exactly: Zone B rows 31-39 (67 = rows 31-37 full 3-3-3, plus rows 38-39 reduced to the right window pair J/K beside the mid-cabin lavatories and Door 3), Zone C rows 40-54 over the wing (129 = row 40 side-blocks-only exit bulkhead behind Door 3 with a centre bassinet bulkhead, rows 41-53 full, row 54 side-blocks-only beside the centre galley), Zone D rows 60-72 (110 = row 60 side-blocks-only exit bulkhead behind Door 4, rows 61-70 full, rows 71-72 taper to 2-3-2 ahead of the aft galley/lavatories). windowAlignment is left "unknown" on every window seat: the published map shows seat positions but not window alignment, and there is no 777 engineering window grid. Recline: Royal Silk 180-degree flat; Economy seatback 110-120 degrees (published as an angle, not modelled numerically).
