1 year old drinkin whole milk

Hi mommas! So my daughter graduated from baby formula, she’s 1 year already, so her nutritionist graduated her from baby formula, but I’m traveling with her on March and what terminal bottles do you recommend to keep whole milk cold during travel, I don’t even know if TSA allows people to pass whole milk, but I know I can purchase the small kids whole milk bottles once I pass tsa at the stores in the airport but I want to make sure the milk remains cold and it doesn’t go bad.
