Do they allow you to use them on planes? I haven't been on a plane in years so I have no idea. I bought ours at Walmart. It wasn't the cheapest but wasn't the most expensive either. I forget what brand it us but can check if you'd like. I keep it in the car but when I bring my son to work with me we bring it inside and plug it in the wall outlet to save battery time. It's great. My son is 3 1/2 and it's definately safer driving for me with the dvd player keeping him occupied. Good luck and if you'd like info on mine I can get it, just email me back. I would definately check with the airlines to make sure they allow them, unless you know already.
