The Thai Airways Boeing 777-300ER carries 348 passengers across Business + Economy. Every seat is rated below, so you can see which have the legroom, the window alignment and the quiet — and which sit next to a galley or lavatory.
The seats rated best on this map are 11B, 11J, 12A, 12K, 14B, 14J. Another 53 seats are rated best or good. Look for 27 extra-legroom seats for the most room.
Seats rated avoid on this map are 36A, 36B, 36C, 36D, 36E, 36F. Another 52 seats are rated avoid. These are usually the back rows near the galley and lavatories, or middle seats with no window or aisle.
Yes — the Royal Silk cabin on the 777-300ER has fully flat beds in a staggered one-two-one layout, so every passenger has direct aisle access without disturbing a neighbour. The forward rows of Business are the quietest.
Window and aisle seats in the side columns of the three-three-three Economy cabin are more comfortable than the centre seats in the middle block. Extra-legroom rows are flagged on the seat map and are the rows to pick first.
The rows closest to the rear galleys see more foot traffic and galley activity through the flight. Choosing a seat in the forward half of Economy, or at an extra-legroom row, will give a quieter ride.
