VS019 and PE on the Boeing 787-900

Hello!
I will be flying PE on VS019 in early November, and it will be my first time on Virgin’s new 787-900. Can anybody who has flown PE on the 787-900 tell me if there are any seats to avoid, or what seats are preferred? I searched the forum and SeatGuru and found no information.
I want to ensure I choose a window seat that actually has a window for my 14 –year old nephew. Thank you for any help you can provide!
