Parents know the importance of packing snacks when traveling with children. However, we don’t heed the same advice when traveling solo. Although snacks are available for purchase at the airport and in the airplane, there is no guarantee that you’ll have time to stop and shop or that your preferred snacks will be available. Unexpected travel delays happen and being hangry doesn’t help anyone. Have at least two non-perishable snacks with you- the more protein, the better.
