On Delta Air Lines, a "Main Cabin" ticket generally does not include a free checked bag for domestic flights within the United States. For these routes, you should expect to pay around $35 for your first bag and $45 for your second. However, "Main Cabin" does include one free carry-on bag and one personal item for all passengers. The checked baggage rules change for international long-haul flights (e.g., from the US to Europe or Asia), where a Main Cabin ticket typically includes one free checked bag up to 50 lbs (23 kg). There are several ways to bypass these fees: if you hold a Delta SkyMiles American Express card (Gold, Platinum, or Reserve), your first checked bag is free on Delta-operated flights. Additionally, Medallion elite status members or those traveling on "Full Y" class economy tickets are often granted a free baggage allowance regardless of the destination.
