Bags may be added to your reservation at the time of check-in. However, checked bags will not be accepted at the airport more than 6 hours prior to scheduled departure time.

Delta Air Lines generally allows passengers to check their baggage at the airport as early as 6 hours before their scheduled departure time. This 6-hour window is standard for most domestic and international flights when checking in at the ticket counter or via curbside check-in (available at many U.S. airports). If you are flying from a major hub or have a very early morning flight, it is always wise to confirm if the specific airport's Delta counter is open, as staffing can vary. For those traveling with only carry-on luggage, digital check-in through the Delta app or website is available 24 hours in advance. If you arrive earlier than 6 hours, you may be asked to wait with your luggage until the window opens for security and logistical reasons. This policy helps manage airport congestion and ensures that the baggage handling systems are not overwhelmed by items for flights departing much later in the day.
