For the "there are two types of people in the world" genre, here's another one: those who can sleep on a plane, and those who can't.
If you're in the latter, there's hope. Here are a few tips to help you sleep at 30,000 feet:
* Bring a neck pillow and an eye mask. And get over yourself. Sleep is more important than looks.
* Noise-canceling headphones. Drown out the awful airplane relaxation station and play your own tunes. Also helps with noisy children and adults who don't turn down the volume on their devices.
* Wear comfy clothing and comfortable shoes. Airlines recommend you don't take off your shoes, in case of turbulence. You might find your shoes in the next aisle. However, you could loosen laces on tie shoes.
* Avoid alcohol, which actually disturbs sleep.
