The completeness of information in a birth record depend on a number of factors: The age, source, and condition of the record, if it is a physical document.

All food that you want to carry on to the plane must be checked in the X-ray machine at the TSA security checkpoint. The food you bring through security must be wrapped or inside a container. This means you cannot send something like an unwrapped hamburger through security.
For long flights, prepare meals to-go. Dry foods are perfectly acceptable to take in carry-ons, so take as much as you need. I typically pack a big salad with meat (pre-dressed with my favorite olive oil) to eat on the plane during meal time.
