If you need any help like delta airlines baggage policy, delta airlines' domestic flight baggage policy, and more information then visit our site. As a significant heritage transporter, with objections in a real sense everywhere in the world, Delta Air Lines keeps things pretty direct. On all flights, travelers are qualified for one free carry-on and an individual thing (like a portfolio, tote, or diaper pack). There's no particular weight limit for portable bags and individual things — which is certainly uplifting news — however, you'll have to ensure your portable fits inside the carrier's size limit.
