Some people recommend you even visit the airport when you don't plan to fly. Just hang out in the terminals and get used to how things are there. This may sound extreme, but it's another way to slowly get comfortable with the flight at hand. Get to the airport early so you have time to experience the terminal, go through security, and find your gate. Being late, or just not having time to mentally prepare for what's ahead, is bound to make you feel more anxious when it's time to take your seat. Get used to the terminal, the people who are arriving and leaving the airport, and the general atmosphere at the airport. The more you get used to it, the better you'll feel when the time comes to board your flight. When you get on the plane, say hi to the flight attendants or even to the pilot. See them dressed in their uniforms, doing their jobs. Pilots receive special training, just as a doctor does, and they are people you should respect and trust. If you practice having faith in these people, and understand that they have your best interests in mind and are competent, then you'll feel better about the trip. Your pilots will have several hundred hours of experience in the air. They'll need to log 1,500 flight hours just to apply to work at a major airline. Many people start ordering a lifetime supply of wine or Bloody Marys as soon as the flight attendants make a first pass. But this is not a good long-term solution for easing your anxiety about flying. Alcohol can actually make you feel more anxious about having less control. This may especially be the case if you’re worried about having to evacuate the plane.  Getting too drunk to worry can just make you feel terrible, especially after the effects of the alcohol wear off. If you really need to calm your nerves, try just one glass of wine or a beer. Distract yourself with a snack that takes a while to eat, or just with your favorite treat. You may be too distracted to do your chemistry homework, but you may have enough brainpower to read about the latest scandal...

How would you rephrase that briefly using Vietnamese?
