I used to hate flying. It's still not my favorite way to pass 3 hrs but it gets me to my destination much more quickly than driving. And there is no way I am driving with my dh that far!!
I flew with my adult dd a few years ago. She hadn't flown very often...about twice in her life, and she was about 32 at the time. She did okay from Providence to MCO. But we had to drive to Pompano Beach to visit relatives. When we flew home, we flew from Ft Lauderdale to Tampa, and then to Providence. Oh man...that short flight between FtL and TPA was a nightmare for her. We didn't fly very high, so it was bumpy all the way. She was in tears and shaking. I kept telling her to just watch the FAs. They were walking around, serving drinks!!
I tell everyone to just watch the FAs...if they are going about their business, you're good to go. If they are in the middle of serving drinks and then turn white and head to their jump seats and buckle in...okay, you may want to start worrying.
This mentality has worked very well, for the most part. At least until we were flying home from London. My youngest dd, then 15, turned to me, as white as a ghost, and said there was a problem. Why, I asked her. She said, look at the FA, she's running down the aisle!! Well, first she wasn't 'running'..she was moving spritely. I told my dd it was a huge plane....it was surprising they weren't wearing roller skates!! The FA just needed to get from the rear of the plane to the front, no big deal.
Really, flying is safe. Bring a magazine to read, wear headphones to block out the engine sounds. Bone up on what is to be expected as far as sounds and movement go. Watch your FAs.
