1. The travelers.You always seem to be seated next  to a baby. And the baby starts crying. And the parents are frustrated because no matter what, the baby realizes that it sucks to be on a plane so it will. not. stop. crying.

2. The boredom. You don't bring enough entertainment with you to properly entertain you during the flight. Now maybe you've got a boyfriend or girlfriend or almost-one-of-those-but-not-quite friends that you're traveling with, and that's pretty entertaining, but at the end of the day you need to bring something that really grips you.

3. The turbulance. No matter how hard you try and pretend that it doesn't bother you, it's pretty freaking scary when the plane starts moving every which way. 

4. The smells. Mostly harmless, the smells you encounter in an airport and plane are enough to keep you awake or at least prevent you from getting a good nap in. Not much to do about this one unfortunately. 

5. The time. As with most things, it takes just as much time (okay maybe a few minutes less) to travel from one city to another in the world as it did 40 years ago. Someone needs to invent teleportation already!

All that being said, I really like traveling, and I like going places.
