Step 2. Do not fight with TSA people. Flirt with them. Tell them you think they LIKE watching you put on your shoes. Tell them you would have knitted something for them if you'd known what colors they like. Ask them if they like your orange luggage. Say, let's take off our coats together. Also, do not fight with the old man. Tell him his cell phone is in his pocket, you can see it sticking out a little bit above his butt crack.
Step 3. After you're in the air, order one gin and tonic, one Mr. and Mrs. T bloody Mary mix, water in ice, and hot water for tea. You may now nibble on the food you brought: almonds, cheese and crackers, peanut butter and jelly sandwich, an apple or orange, Australian licorice.
Step 4. Always do something. Write in your journal, read a comic book, knit. Never never never watch television. If you do watch television, only watch it with the sound off. You'd be surprised. Always bring ginger gum in case you feel sick. Also, always pack lightly. You don't need underwear every day, right?
