I suspect what we’ll see (in relation to 772 and 773 refits) is
- A contraction of F area and a reduction in the number of F seats
- An expansion of CW area and possible increase in the number of CW seats
- An expansion of WT+ area and increase in the number of WT+ seats
- A contraction of WT area but seat numbers remain largely unchanged due to 3-4-3 densification
