Re: Sleeping v/s movies
The key is to not sleep the day before or so. On my last trip to Pakistan, I did all my packing/last minute errands the night before the flight. Hardly got any sleep. Had work the next day and flight the same evening. So by the time I got on the plane, I was exhausted and slept like a baby through most of the flight.
Sometimes it’s also illness that can knock you out. This one time I was travelling back from Pakistan and I had very high fever. I took medicine and slept all the way back. My parents told the air hostess not to wake me for food.
Under normal circumstances though I do find it hard to sleep in the plane for more than a couple hours at a time. I watch movies to kill time.
