How can i treat my anxiety when i'm on an airplane?

There are a few: Techniques that can work fairly quickly. Cognitive behavioral therapy using progressive desensitization (learning to relax & then imagining the phobic event from least to most anxiety provoking image while relaxed. I usually do this using hypnosis as a relaxation technique, but you can use other relaxation methods. Find a therapist & you will be able to get relief fairly quickly.
