I have a severe flying phobia that debiltates my traveling life. My husband & I drive nearly everywhere - including 17 hours to Florida every single time. My biggest fears are w/mechanical errors, but since 9/11 I have developed a fear of terrorism too.
Here are the things that I do that help me, when I absolutely HAVE to fly. Most importantly - ask to meet the pilot. Anyone of any age is allowed to do this, I'm in my 20's. I usually go early to the gate & let someone know ahead of time that I'm afraid to fly & would like to meet the pilot for comfort purposes. I've never been denied or looked at funny. For some reason, no matter what the fear, knowing who is flying your plane provides a sense of comfort. Next, let the flight attendant know that your kids are scared. He or she usually provides extra attention to those who are scared, reassuring them & talking to them from time to time. Knowing that these people who are talking to you fly multiple times a day, every day, all year is comforting.
Another reason I arrive at the gate early is to people watch. I don't stereotype people, but it simply helps to see people talking, reading books, listening to music, playing games, etc. You get to see the people you'll be flying with as real people, and it helps to take the place of the fear. While on the plane, definitely keep them busy with games/books/movies & other things. For me, once I'm up in the air the fear dims a bit. It's the leading up the flight & the boarding that create the most panic. Of course everyone is different, but these are just some things that work for me.
