No — Travellers in the standard Delta Air Lines Main Cabin fare typically do not get a free checked bag by default. The airline charges a fee for the first and second checked bags on many U.S. domestic routes.
That said, there are exceptions: certain international routes include free checked bags, and passengers with elite status or co-branded credit-cards may get free checked bags even in Main Cabin.
