To date I’ve been in 12K & 13A in CW on the triple seven & have not noticed a problem with the view. Yeah the wing is there, but that’s kinda cool too, to watch all the spoilers, flaps, slats etc do their thing. Maybe I’m just warped but I love to watch the wing flex during turbulence.
Also at the risk of being flamed by the “anti 777” crowd, I’ve not noticed any particular problem with the CW cabin on the 777. Don’t see that much difference between it & the lower deck on a 747.
Just more seats that’s all !!
Mind you though it was on overnight flights that I’ve travelled on the 777, maybe a daylight flight might be different, but can’t really see how.
