Roberth66 makes a good point about the timing of the failure - it's always at 3am over some random state when you're half asleep. That's why I think the hoodie trick is actually the smartest move, since you're already packing it anyway and it doubles as a backup plan. Morganmartinez really nailed it with that sweatshirt idea, cheap pillows just aren't worth the gamble when you're stuck in a middle seat for six hours.
