Been reading a bit about seating on here - my wife and I took pretty much the last two seats available to select, on the back row but not together (see picture below). Sounds like it will definitely be worth doing early OLCI in case any pair opens up. However, failing that, do you think the person between us in row 17 would have an issue swapping to the window seat? Can't imagine anybody would prefer to sit in the middle if they were on their own, but perhaps there is something I don't know!
Cheers
