The only real long flights that I have been on, I was lucky enough to fly first class. And even then it is allmost unbearable. You will probably sleep a lot. Maybe if your going to India, bringing a lap top or a DVD player isn't something you want to pack along (I'm assuming your packing light I mean). Bring a book. Seriously, long flights suck. There won't be much to do and you will be kissing the ground when you get to India.
