*Record some of your favorite music on a cassette and put your head phones and play that music loud while you are taking off. Once I am in the air I usually relax because physically I feel better, no more popping of ears. Taking off and landing are the worst times for me. *Also find a really good book to read, (maybe the Unoffical Guide to WDW), something that will engross your mind.
*Sit in an aisle seat, it is less claustrophobic & easier to get to the rest room.
* Getting up periodically and going to the ladies room gives you something to focus on rather than your fear. *Also keep reminding yourself that there is really nothing to be afraid of, that the fear is only in your mind.
* Realize that many of the brave looking people on the plane with you are just as nervous as you and try to make a joke of your fear and not take it too seriously. *Tell your husband to keep up the conversation to distract you.
*Keep your eyes on the prize i.e. focus on the end result, that once you get off the plane you will be at WDW !
*Sit next to a stranger, you are less likely to be nervous in front of one. One flight I sat next to a nice man who told me all about how he was coming back from visiting his dying sister (cancer) it made me realize that my fear of flying was inconsequential in comparison to other peoples load and it made me actually happy to be on a plane with loved ones going on a vacation.
* As a last result Valium taken 1 hr before boarding also works or a couple of drinks. Sometimes just having medication with you and knowing that you can take it at anytime you need it is just as good as actually taking it.
* Get angry at your fear, face it like the enemy it is and don't let it stop you from enjoying your life.
* Good luck, I will be flying again in August and I hope you wish me luck too !
