Hello, this is my first post here, sorry if this question sounds dumb or is not in the right section of the forum.

I have to select 3 seats in Economy class, we go in a Boeing 747-8I and we return in an Airbus A340-600

2 of us like windows seats and one of us isle.
I as a first approach selected rows 30 and 31 for the Boeing to the right and rows 37 and 38 for the Airbus to the left.

I guess somebody here has actual experience and could provide some advice.

Thank you in advance,
Brad.-
