It depends how you view the importance of IFE, I suppose. For me I use IFe as part of my procedure on an overnight flight. Pick a good film that I like, and I'll fall asleep in front of it after a meal and a few drinks. If I can't find anything I like or the IFE is playing up, I will struggle to sleep. What really annoys me is when BA put part one of a DCI banks programme on but not part 2. I still don't know how it ends as I haven't found that episode being shown on ITV3 lol
