DO intervene when you recognize yourself thinking about the part of flying that makes you anxious. Tell yourself to stop the negative thoughts abruptly and replace those thoughts with a calming peaceful thought. Imagine pleasant life affirming events occurring in as much detail and real time as possible.

DON'T rush to make a flight. Rushing causes anxiety that can stay with you the entire flight. Get to the airport early. Most airlines recommend one hour for domestic flights and two hours for international flights. Settle down and walk onto the plane in a relaxed manner. 

DO eat nutritiously (protein and unrefined carbohydrates) before a flight. Sugar and caffeine may give you a momentary jolt but you will soon feel a sugar crash. Be sure to have something to eat every 3 1/2 hours. If you have comfort food that you enjoy, bring it with you.

DO learn to breathe from your diaphragm. Put your hand on your belly and breathe in so deeply that you feel your tummy bulging out a little. Breathe slowly and deeply for 10 cleansing breaths.
