The aisle seat passenger wont get kicked by the passenger behind but it may be annoyed by window seat passenger walking pass by holding aisle seat back.  

Cathay Pacific is much better. I had 2 bookings with them in business class to Japan. They gave me full refund in 4 weeks due to flight cancellation. Emirates is not good enough. What happen if I am not going to flight in the next couple months. I will stick with Cathay Pacific in future.
