I am flying with my baby this weekend and will be gone for a week.  We are taking n unopened container of ByHeart in checked bag!  You are able to take formula through security if you want to keep it in their diaper bag. 

Hi Ashley!  Happy to help with this. To ensure the highest quality, we do recommend storing ByHeart in its original can. That being said, we reached out to our quality and product team, and they provided us with these instructions for storing in another container!    If you are transferring to a different container, ensure the following:  1. It is suitable to hold food.  2. the container is totally clean and sterilized and completely DRY before use.  3. Only transfer the powder you will need for that day's use  4. Keep in a cool, dry place. Let us know if you have any other questions!
