I have never flown a B777, but I believe it seats nine across each row.
Is it a [3 - 3 - 3] format?
Or a [2 - 5 - 2] format?
The first one makes more sense since it is more evenly arranged. But I remember friend of mine told me once that he sat in the dead center seat of the middle five seats.
The original configuration of coach seating in the 777 was 2-5-2. Most airlines have changed it to the more logical 3-3-3 configuration

The 777 cabin width is only 9" narrower than the 747. Shave a quarter inch off each 747 seat and 3" off each 747 aisle. Skip the double armrest in the middle of the four to recover an inch on both aisles.
That was it…it was American Airlines that my friend flew from Tokyo-NRT to Dallas/Fort Worth. He sat in the dead center of the middle five.
I imagine the 2-5-2 version is favored if you’re sitting on either side of the cabin; but if you’re going to be stuck in the middle five, then it’s not so good I guess.
One thing about the 2-5-2 seating: There was a lot of controversy about this setup when Boeing announced the 777. It was considered a stupid arrangement. I’m just amazed that some airlines still have it.
There’s been a lot of thought put into 3-3-3 vs 2-5-2. It’s pretty interesting, really.
In a 2-5-2, there are fewer people in a middle seat with someone next to them on most flights. Additionally, with 2-5-2, only one person has to get around two people to get to an aisle whereas with 3-3-3, two people do.
People often travel in twos, too, so you can seat four pairs of twos “alone” In 2-5-2 configuration with one empty seat.
