i was reading up today on the juice issue. you can have juice, a bottle, or breast milk, but it has to be in a quart size bag and you have to tell them you have it when you check it. i'm going to call the air line next week to double check on anything i need to do. thanks for the tips guys. and no my vest bage does not have wheels. i plan on putting aj in my jeep carrier that i have still thankfully. he may throw a fit at first being in it, but he used to love it. he hasn't been in it in a while.
