I know how you feel. This is how I get any time I have to travel...especially if I know that others are counting on me having a good time. For the flying, I found learning more about flying and pilots(their training etc) made me feel a lot better about flying in general. Also, it always help me to ease into a trips activities...meaning I take my time getting to know my surroundings(hotel room) and then have a low key activity planned for the first day. That way you don't have the added pressure of feeling like you might let your hubby down if you have a bad day or a PA.
This technique helped me tremendously when we went skiing...I have big time anxiety about mountain tops..the wind, etc...and planning our skiing for just a half day the first day and a nice cozy dinner that night gave me an achievable goal and I did not feel like I deprived my husband of anything.
Hope this helps a little.
