Maybe it's the fact that you can't really lay anywhere's near a flat position when your seat is "lowered" on an airplane. I can never feel comfortable on those dam long flights. The seats just aren't that comfortable to begin with, maybe first class is better but we don't fly that way. Even with a neck pillow it doesn't change my comfort level. If we could only afford our own plane with a queen sized bed. A good strong sleeping pill is what I should really take before our long trips. Something that will knock me out before we leave and let me wake up refreshed when we land. Unfortunately, there isn't any such item on the market.
