Food can usually pass the security checkpoints if you want to carry it on.

Oh good, Thanks :) ! ...so I have to make sure it fits in my 1 quart zip bag?

There are no checks that I know of for food products on domestic flights within the USA, other than the normal checks that apply regarding carry-on luggage. (Kind of makes me cringe to use the word ‘normal’ in that sentence.)

If I were you I’d pack your food items in a checked bag and in a hard-sided container so they don’t get crushed. That way you won’t have to subject them to inspection as carry-on, and they won’t be confiscated because some idiot agent gets a hair crosswise.

If you were flying from overseas into the US, then a whole raft of rules certainly do apply regarding what may or may not be imported, but not on domestic flights.

I agree that you should try to pack them carefully and put them in your checked luggage. Security is all kinds of insane about packing “liquids” and “gels” in your carry-on bag. They made me throw out a jar of peanut butter once.

If possible freeze them, you never know how long you will be stuck in an airport waiting for a delayed flight.

Food is fine to bring on domestic fllights.

FYI – When we are coming back from Florida, we often carry sandwiches on the plane in a plastic shopping bag. We probably look like we are just off the boat at Ellis Island. The only time we had trouble was the time we were carrying a hothouse cucumber that didn’t show up well on the scanner.
