Yes, Delta usually charges for checked bags, but the exact fee depends on your route, fare type, and membership status. For most domestic U.S. flights, Basic Economy and Main Cabin passengers typically pay for their first checked bag, while higher fare classes and elite SkyMiles members may get free allowances. International routes often include at least one free checked bag, but this varies by destination. It’s always best to check your specific booking details or use Delta’s baggage calculator so you know the exact cost before traveling.
