-Get to the airport in plenty of time and stay positive and cheerful even if there’s such a long line that you think it must be leading to Timbucktoo and not to the check-in desks.
-Buy a bad cup of coffee, even if you’re not going to finish it because it’s too hot/cold/icky, because it’s traditional and social.
-Get something chocolaty to bring on the plane with you. You never know when you’ll get a sweet tooth.
-Make eye contact with security people. They like it when you smile as well.
-Think about how much time you still have left to travel. Breaking down and crying in the middle of airport terminals in dispair is not a socially acceptable thing to do.
-Talk and joke loudly about the bombs in your luggage. You’ll end up missing you flight due to sitting in a cold room with a lamp shining in your eyes while tiny security people try to get you to confess what you’ve done.
-Sleep before a flight. You’ll want to fall asleep on the plane, not be wide-eyed, jittery and full of adrenaline.
-Begin conversations with people in the lines. You’ll end up needing to sit with them and hear all about their Uncle Morty’s social problems at his job and how many kidney stones they’re having taken out the day after tomorrow.
-Lose all hope for ever reaching your destination. Once again, public-meltdowns are not socially acceptable.
