Family of 4 traveling from LHR-JFK. World Traveler. Currently assigned seats are 31 A/B, 32 AB. i.e. window/middle, followed by window/middle.

I see that rows 46/47/48 are also available. These rows have 2-3-2 configuration, with no middle seats on the two sides. Are there any downsides to taking 46 and 47 A/B? There seem to be windows on these seats - right?
