I have checked out seatguru.com and I am still confused. We will be on a four class plane from JFK to Kenya, stopping in London. The business class seats are 2-4-2. Seat Guru suggests booking the two center seats (leaving one seat on each side) if you are traveling as a couple. These are both rear facing seats. Can anyone confirm that these are the best seats to book?? Someone else suggested that I try and book two aisle seats, across from each other.
