Our worst flight was on our very first time to WDW with our young kids. Our daughter was 5 and our son 7 y/o.
The flight down on Delta was great, and the kids loved flying.
Then on our return flight, the plane we were to fly on had problems, so they were flying a different plane down from Minnesota (the hub for Delta). We had a 12 hour wait!!! with 2 very tired kids. They gave us each a $7.00 voucher for food. I guess you know how much that covered? barely a sandwich.
Once the plane arrived and we boarded, we took off. We got to cruising altitude for the plane, and the captain did not get on the intercom and tell us to remove seat belts, the flight attendants would be around soon, etc, etc, like they usually do. It was quiet and the attendants did not get up from their seats.
All of a sudden, we dropped nose down for what seemed like a long time! People were screaming, yelling, and scared to death. It looked like something out of a horror movie. I was freaking too, but could not show it because I didn't want to scare the kids more than they were. When it was finally over, the captain finally came on and said that we had some turbulance. You think??? That's it. There was no announcement about bad weather or a rough flight at all, we just dove down! IF we had a warning, we could have been prepared. Afterwards we found out that we apparently were caught in the tail end of a tornado!!!
My daughter hid under my arm and under a blanket for the whole flight home to Mn. My son slept, though I don't know how he did it? He has not been affected by that horrible flight, but to this day, my daughter has to work through fear of flying. For years, when she was younger, she was very scared of any flying, and we did fly to Orlando several times.
Thankfully, since then, we have had no problems and always fly Delta.
