Helpful products when flying with an 11 month old?

Jami

Hey there! My husband and I will be flying for the first time with our 11 month old son. I could use any tips or product recommendations that helped you when you flew with a little one. All I have so far is noise cancelling headphones for him so he can hopefully sleep on the plane. But I have no idea how I'm going to keep him entertained for 2 1/2 hours if he doesn't want to nap!
