Ava's First Plane Ride

Michael was fortunate to have the opportunity to visit the Semester at Sea ship in January. They set sail from San Diego to Ensenada, Mexico and returned a few days later. Ava and I set out to meet Michael in San Diego for a long weekend.
Ava and I boarded our first flight in Indianapolis and Ava was an angel. She wanted to go "night-night" and snuggled up in my arms the second we boarded and didn't move until we got off the plane for our layover in Houston. She enjoyed looking out the window at the scenery and didn't fuss a bit. For our second leg we got on board and little Ava was good as could be. She played on the floor for a bit taking magazines in and out of the seat pocket. She said "hi" to everyone boarding and then she finally curled up in my arms and fell right asleep. When we got off the plane in San Diego she was beside herself that we were getting on a bus for the hotel. She repeated "bus" "bus" in her excited, happy little voice. Once we arrived at the hotel and she saw daddy waiting for us she squealed with delight and pointed and screamed "Dada". She was thrilled to see him again.
For the next 2 days of our weekend getaway in what was supposed to be sunny San Diego we were hit with torrential rain and 40-50 mph winds. One entire afternoon and evening was stuck in our hotel. The second day we managed to get a rental car and drove to Balboa Park, Torrey Pines State Park, and Ocean Beach. The weather was cool with a light mist which turned to torrential rainfall for the remainder the afternoon. As luck would have it the sun came out the second we got to the airport for our return to Indiana.
And our fateful return to Indiana....Ava did not repeat the excellent behavior from her first flights. Oh no, instead she could not be satisfied in any manner. She threw her pacifier over my head and hit the gentleman behind us and screamed for at least 25 minutes of our 45 minute flight to Phoenix. I was finally able to get her to sleep by rocking her in my arms and letting her scream it out. It was torturous for everyone on that flight. We were supposed to be able to remain on the aircraft for our return to Indianapolis, but when we arrived in Phoenix we had to change planes. This, of course, resulted in another 20-30 minute screaming fit until Ava finally wore herself out again and fell back asleep. We got to Indianapolis around 1am where Ava was suddenly her happy, delightful little self again.
What is it about plane travel that turned my child into the devil? I'll never know because that's NOT happening again until she's say 20?!!!
