Navigating Delta Airlines’ baggage policies involves understanding the allowances and fees associated with both carry-on and checked luggage. Passengers are allowed one carry-on bag and one personal item, with size restrictions of 22 x 14 x 9 inches for the carry-on. Checked baggage fees vary based on destination, class of service, and frequent flyer status, with size limits of 62 inches and weight limits of 50 pounds for economy and 70 pounds for business or first class. Special items and oversized luggage incur additional fees. Familiarizing yourself with these policies ensures a smoother travel experience.
