How do you keep food good on a plane?

If the food you're traveling with needs to stay at refrigerator temperatures, pack it in a cooler that can be counted as checked luggage. For longer flights, or times when you suspect there may be delays, consider freezing the item you're flying with, especially if it's a meat, casserole, or soup.

The key is to choose fillings that keep well for a handful of hours without refrigeration: cheese, cured meats (think prosciutto), hummus, grilled vegetables, and greens.

Tip #2: Reduce waste and save some money by bringing a reusable water bottle. So you can't bring H20 or any other liquids more than 3.4 oz. (well there are some exceptions) through security, but you CAN bring an empty bottle. Just fill it up on your way to boarding your flight after screening.
