My wife wanted the aile seat and I always prefer window seat. Luckily we both got the best seats we wanted. The plane was very nice and we enjoyed the best take off and the smooth landing at Toronto. All the services by the staff inside the aeroplane were very nice well appreciated. Thanks again and hope to see you soon.
