After over 40 flights with kids we have found what works best for us. I always include some type of craft this time the sticker art (3 years and up or they will get frustrated). Also some type of play doh or sensory toy. Then when they are tired or ready to relax they have an iPad and PBS kids games. Don’t forget a blanket because it’s always cold 🥰 LTKKids LTKTravel LTKFamily
