There are several ways:

1. Figure out what causes your fear:

Find out what makes you afraid and discover how the reaction that makes you anxious is caused. Finding out what triggers it when your anxiety level is not yet elevated can control your fear.

2. Enrich your knowledge before flying

Anxiety can arise from ignorance, accompanied by the tragic thought, "What if...?" of miserable thoughts. But if you have insight, the "What if...?" thoughts will be limited by the truth. Familiarize yourself with the truths as much as possible. They won't eliminate your anxiety, but they will help you to control it.

3. Anticipate your anxiety

Anticipatory anxiety refers to the anxiety we feel when we anticipate our fears. It's usually the most intense anxiety you experience during a flight, but it doesn't accurately predict how you'll feel on the airplane. It is usually far greater than the anxiety you actually experience.

4. Separate fear from danger

It's often hard for people to separate anxiety from danger because your body reacts to both in the same way. So make it clear that your fear is just anxiety, not danger. Tell yourself that anxiety makes you more prone to scary thoughts. Remind yourself that feeling anxious does not mean you are in danger. You are safe even when you feel intense anxiety.

5. Intuition from anxiety can be misleading

(1) Anxiety can trick intuition: when you are very safe, anxiety can lead you to believe that you are in danger. In these situations, your intuition will always tell you to take cover, but if you follow those intuitions, it will reinforce your anxiety instead.

(2) You can beat anxiety: in general, do the opposite of what anxiety is trying to lead you to. Fight what anxiety tells you, but accept the discomfort it brings you.

6. Eliminate Anxiety Caused by Bumps in Flight

To control your anxiety when you encounter turbulence hitting the airplane, it's a good idea to learn something about airplane construction. At the scene, focus on controlling your anxiety and don't think about how the turbulence will end or how serious it could lead to. Remind yourself that you are safe.

7. Tell fellow travelers how they can help you

Fellow travelers need to know what scares you and how to help you cope with in-flight anxiety. What you need to do is figure out the anxiety triggers and suggest useful and specific ways to help your peers.

8. Value every flight

Exposure to fear is an effective way to overcome phobias. Each flight provides you with an opportunity to make you more relaxed the next time. What you need to do is remodel your brain so that it becomes less sensitive to the causes of your fear.
