Before you step on board the plane, you'll need to show some type of government-issued ID, such as a passport. You'll also need your boarding pass. If you're traveling with children, check with your airline about which documents they require — if any.
Take some activities to keep you occupied on your trip to Illinois. Books and electronic devices like tablets and laptops will do the trick. Be sure to take a water bottle with you too. Even on a short flight, it's important to stay well-hydrated.
