There are many different treatments used for people with flight phobia. Some people may only need confirmation, while others may require long-term treatment. Treatment is really based on the fear and the extent to which it affects the person.
The main treatment for the fear of flying is to provide the person with information about flying. Basically to educate them about how safe it is and to prove that their fears are irrational. It is also very helpful to provide an opportunity to cool off and relax on the plane. This treatment works for mild forms of phobia.

Some people can benefit from relaxation techniques. You just have to learn to let go of your fear and relax so that the fear goes away. This treatment is best for people who have negative thoughts about flying and whose phobia is based on that stress and fear.
In extreme cases, professional treatment may be required. Fear can come from something that happened to someone in the past. It can be ingrained and until you face this past fear, you cannot overcome your fear of flying. It can take months or even years to resolve the underlying problem so that the fear of flying is gone forever.
The fear of flying often comes from something else. To overcome the fear of flying, treatment is usually based on addressing the underlying problem causing the fear of flying. This may include claustrophobia or the fear of vomiting on planes.
