Hi LisaJane,
I have flown both the 787 and 380 to/from HK and SIN multiple times in the last few months. The 787 seats are new, lots of storage, great with access to power etc, but......if you are over 5’10” the seats have a lot less leg room, and the seat pitch / recline does not seam as good as the “ Older 380”
I’m 6’4” and I was gutted to hear QF is upgrading all PE to the new 787 seat ☹️
