Can I take prefilled sippy cups (juice) and baby bottles (formula) on a plane?
This is a tough question because unfortunately all security at all airports is not the same. The first thing you can do is to check the TSA website to see if they speak about baby bottle restrictions. Another thing you can do is take powdered formula and empty bottles through security and then fill them when you get past security with water/milk that you can by at the shops or snack food counters in the airport. As far as sippy cups…no you cannot bring sippy cups through security with liquid in them. You can bring the cups empty and once again buy juice when you get through security. Or you can ask when you are in flight for juice for your child. That is what most people do. Here is the TSA webpage dedicated to traveling with children, it should answer all the questions you may have. http://www.tsa.gov/travelers/airtravel/c… Good luck and have a great trip!
