There is so much nonsensical noise that is being made on the 10 abreast that it is death defying of some individuals bias and opinions.
Simply incredible reading some of the comments on this topic.
Let's start with EK, BR, NZ, AF and all the other carriers that have 10 abreast seating for their 777 fleet.
If CX 10 abreast is making your life complicated, fly other carriers.
I have flown on the new CX Y class with 10 abreast seats and I think its comfortable.
Happy travelling
