The LATAM Airlines Boeing 777-300ER carries 410 passengers across Business + Economy. Power is available on this aircraft. 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 1A, 1L, 2C, 2J, 3A, 3L. Another 56 seats are rated best or good. Look for 30 extra-legroom seats for the most room.
Seats rated avoid on this map are 15L, 18L, 19A, 19B, 19C, 20A. Another 44 seats are rated avoid. These are usually the back rows near the galley and lavatories, or middle seats with no window or aisle.
It is a full lie-flat cabin in a staggered one-two-one layout, so every seat reaches the aisle directly and the product is pitched at long-haul flying. The seats are broadly equal, which makes position the main call: forward seats are first on and first off, and window-aligned seats feel more private.
The bulkhead rows behind business give extra room, though they lose under-seat stowage for take-off and landing. Elsewhere a window or aisle seat avoids the middle seats, and rows away from the rear galleys and lavatories are quieter on a long overnight sector.
The very back rows near the rear galleys and lavatories carry the most noise, light and traffic through a long flight. In the wider centre block, the true middle seats are the least comfortable, so a window or aisle is worth seeking out on a long-haul leg.
