Took my 8 year old in J last year AKL - YVR, sat 4A/5A. Woke up about the 9 hour mark, my son was wide awake watching a movie he wouldn't be allowed to view at home. A last minute flight change on the return meant we ended up with a skycouch each in Y. He said he actually preferred the skycouch over 4A - said it felt more 'secure' with the front and rear seat backs kind of holding him in more and there were other kids around which made him feel more comfortable. Easy to get a good sleep on a skycouch when you are 4 feet tall!
