How to sleep comfortably on a plane

Note: these positions may require the use of a pillow, blanket, and/or tray.

Hello readers! Today, I will tell you about some comfortable sleeping positions that you can use on a plane.

1. Requires: pillow
If you have a window seat, just lean your head against the wall! Optional: Cover self in blanket.

2. Requires: nothing
Curl your knees up to your chest. Optional: Cover self in blanket. If you're wearing a hoodie/sweatshirt, you can pull the hood over your head.

3. Requires: blanket, pillow, tray
So you know how, on a plane, there's a tray you can fold down and eat your food on it? You can sleep on it too! Fold down your tray. Place the pillow on it. Cover self in blanket. Rest head on pillow. Note: do not do this if you feel your head is heavy.

Use the sleepmask the airline (hopefully) gives you. If you do not have one, bury yourself in your sweatshirt. If you don't have a sweatshirt...all I can say is that you need a packing list next time. 
Even if you're going to a tropical island, you NEVER know what the weather will be like!
