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.
It can get very cool on the plane. If you'd prefer not to shiver your way through the flight, wear an extra layer of clothes.
