13 year old going on a plane ride... what should i bring?

I have to be doing SOMETHING at all times. i am going on a flight from fl to az by myself over the summer. what should i bring??? i found out that i can't have my cell phone on and that saddens me because i am a textaholic and idk if i can go how ever long w/o texting.. but thats besides the point. so any suggestions??? list form helps :) oh ya and any websites i can go too??? that would help too!!
