What can i do on a airplane ride?

i am going to Florida in 2 days and i need entertainment for the long ride. i am going to bring my MP4. i am going to put videos on it. a few sonny with a chance shows and the movie jack 3. i think that will last me but what if i get bored? is there a website that i can check out to find printable pages of games? this is not my first time going but i find i can get really bored after an hour. i am in the middle of a book. should i bring that?
