“Traveling International? Bring a pen with you. The longest lines you wait for at customs is for the damn pen. 

Pack a plastic fork and spoon with you. I hate showing up to my hotel with some instant noodles and then having to use the coffee stirring sticks like chopsticks to eat it. 

If you’re tall, mention you have problems with your knees at the check in counter. Sometimes they’ll find you a seat with more leg room. “
