This is the Boeing B777-300ER Air China livery.
I personally like the Air China livery because it was the first B777 I’ve ever flown, so I sort of have a connection to it. (I sound crazy, don’t I) This livery would be a good addition to the game, as I think Air China deserves more liveries like this.
Anyways, the B777-300ER is one of the most widely used aircraft of Air China, along with the 200ER and the A330. The livery may seem simple, white top and gray bottom with some blue lines and letters, but I think that’s why I like the livery, because of the simplicity. As an American, I think that the livery would bring more love to Asian Airlines.
