So if they add another column of seats to make the 777 10 abreast, wouldn't that be adding to capacity?

I hope CX don't start going down the route of BA and "enhance" everything within an inch of its life. I've just recently started flying Cathay and have made it my first choice of travel between the UK and Australia, even though it is often at a premium compared to some other airlines. I've done 2 trips so far in the last 10 months and the next one booked in a few months time. And I've been spreading the word on social media too. Maybe I should reign that in for a bit.
