The 3 previous comments reflect my opinion. Pages tear-proof, clear text, interesting, full ... I just wanted to add that I used this book to prepare my 2 year old and a half to its first flight. Well, it is impeccable! All steps being illustrated, we have "followed" the book in the terminal, the security gate on the plane ... I gave him the next step, we spoke again to the previous step. And besides, it was very busy during the wait! Today, this book is a memory. When we read, we often stop and wonder, "Do you remember?"
