Clean and nice interface. The screen quality is better than most airlines.
Additional seat pockets for passenger to keep their stuff. This good to keep my phones, water or maybe medicine. The cup handle also provided.
Although I just in economy class, but I get free ear phones with plane adapter. Good strategy especially if your passenger always bring to use the ear phones when they are flying no matter in which airlines.
High quality and like a PlayStation Vita type of console. Some airlines only provide this kind of console in business or first class.
Proper menu booklet for economy class.
