Preparing your belongings according to the Delta Airlines carry on policy can make traveling more convenient and stress-free. The airline generally allows one standard carry-on suitcase and one personal item without an additional fee on eligible flights. Your cabin bag must measure no more than 22 × 14 × 9 inches, including wheels and handles. Pack clothing, electronic devices, travel documents, and permitted toiletries efficiently to make the most of your available space. Remember to follow airport security regulations and verify any route-specific restrictions before departure to avoid unnecessary delays during check-in and boarding.
