Hangry. It is better to be over prepared than under prepared. You never know what could happen during your travels. Your flight could get delayed, your hotel could be overbooked, your rental car could break down or your credit cards could get stolen. To be prepared make sure to bring extra snacks on your carry on and checked bag just in case an emergency arises.
One of our favorite travel snacks is Nature Valley Crunchy Bars. Snack on.
