Things I hate about other fliers:
1. Men that don't wear socks on a plane. This isn't your house, it's an airplane. Wear some socks.
2. Pulling on my seat when you get up. I don't care how bad your legs hurts or how fat you are, my seat is my seat. Stop pulling on it. (I HATE THIS THE MOST!)
3. People that bring food onto a plane that smells. Bringing a snack/sandwich is ok, but don't bring the fried chicken/Indian food/etc. that stinks up the cabin. I don't care. If you wanted to eat your own food either (1) schedule for a time that doesn't interfere with your meals or (2) take the bus.
Vent over.
