I think we should do that before our trip as well. Her family went to the courthouse with backpacks full of belongings to practice going through security, as one of their pre-flight activities. She is raising four special needs kids and did an extensive preparation period before they took their first airplane trip.
I highly recommend checking out the blog post at Every Star is Different.
The best part is that you can print this book off as many times as you'd like (personal use only), so your child can color it on every flight! I recommend these twist up colored pencils for coloring although triangular crayons might be better for some kids, as they won't roll off the tray table. Your child can work on the pictures while on the plane. There are 16 pages, which includes the text from the social story and a few more fun prompts. The coloring book is set up to be printed back to back and folded into a booklet. These one should be fine and hopefully the others will as well. They messed up my entire library (almost 1000 between my two blogs), and I'm still trying to get them all fixed. If you're having trouble with my other printables, blame Google. Then, review one card at a time just before you experience it on the journey. Read through the cards frequently before you get to the airport. I included a spot on the cards to guide your hole punching, so you can put them on a keyring or lanyard. I recommend cutting them apart, and then laminating them for durability. The color printable includes 12 cards that you can print and use before and during your trip. So hard! The story talks about arriving at the airport, checking bags at the ticket counter, going through security, boarding the plane, behavior while on the plane, and other important things your child needs to know. My goal with this social story was to cover all the major moments in airplane travel, while still keeping the context short and simple. The creator made it super easy to make the social story with a matching coloring book. I am so happy that she offers her art in both color and black and white. I found all these great airplane travel graphics from Educlips on Teachers Pay Teachers.
