I know Seatguru will have plenty of details about individual seats, but I just booked tickets for my mom and dad, and I'm not sure what the best seating arrangement is for the two of them. Obviously with the setup two people can't really sit "next" to eachother. If they want to converse, is it easier if they are right behind each other? Or if someone has the aisle and someone is on the right? Which side is best? Thanks!
