If I get this off my chest here I might have a better flight next time
  1. People who don't understand wheels in
    Overhead luggage goes wheels in. Not sideways. And your jackets don't belong up there.
  2. People who frantically jump up once you've landed
    If you don't have a connection leaving in 5 minutes - crowding people out so you can move up 2 rows is obnoxious.
  3. Confused security line people
    I flew yesterday. The guy in front of me at security had on cargo pants with every pocket stuffed to the brim. He'd take one thing out and then try to go through the metal detectors again. This took many minutes.
  4. People who demand a special meal
    But didn't bother to put in a request ahead of time.
