In 2026, Delta Air Lines' baggage policy for economy passengers depends on the specific "brand" of economy you purchase. Basic Economy (Class E) tickets do not include a checked bag; you are only allowed one personal item and one standard carry-on bag for free. If you want to check a bag on a domestic Basic Economy flight, it typically costs around $35 to $40 for the first bag. For Main Cabin (standard economy), the first checked bag is also usually a paid add-on for domestic flights unless you hold a co-branded Delta SkyMiles American Express card or have Silver Medallion status or higher. On most international long-haul flights (e.g., USA to Europe), Main Cabin tickets still include one free checked bag up to 23kg (50 lbs), while Basic Economy often requires a fee even for international routes. It is always best to check your specific itinerary in the Delta app, as 2026 pricing for "ancillary fees" like baggage has become increasingly dynamic based on the route and the time of booking.
