The Air China Boeing 777-300ER carries 392 passengers across Business + Economy. Power is available on this aircraft. Seats are 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 31A, 31B, 31C, 31D, 31E, 31F. Another 46 seats are rated best or good. The map marks 30 seats with extra legroom.
Seats rated avoid on this map are 39C, 39D, 39E, 39F, 39H, 39J. Another 72 seats are rated avoid. These are usually the back rows near the galley and lavatories, or middle seats with no window or aisle.
This is the high-density version: it drops the First cabin and runs a tighter ten-abreast Economy, so it seats many more passengers. Business is still a lie-flat, but if you want the three-cabin jet with First, check the map for your flight.
Yes. This variant runs a denser ten-abreast Economy than the three-cabin flagship, so the seats are a little narrower. Choosing an outer window or aisle and a bulkhead row for legroom matters more here than on the roomier layout.
Yes. Even in the high-density configuration the Business seat is a full long-haul lie-flat. The cabin is smaller than on some layouts, so front-to-rear position is the main thing to weigh when choosing a seat.
