Travelers can simplify their packing decisions by understanding the difference between a personal item and standard cabin luggage. Under the Delta Airlines carry on policy, passengers can generally bring one carry-on suitcase and one personal item without additional charges on eligible flights. The suitcase must meet the 22 × 14 × 9-inch size limit, including handles and wheels. A purse, briefcase, or compact laptop bag can serve as a personal item if it fits beneath the seat. Reviewing the applicable restrictions before traveling helps passengers organize their belongings and avoid potential boarding complications.
