For standard "Main Cabin" and "Basic Economy" passengers on Delta Air Lines in 2026, the checked bag weight limit is 50 lbs (23 kg) per bag. If your bag exceeds this weight, you will face "Overweight Baggage" fees starting at $100 for bags up to 70 lbs. However, travelers in Delta One®, First Class, and Premium Select enjoy an increased limit of 70 lbs (32 kg) per bag as part of their fare. Additionally, SkyMiles Medallion members (Silver, Gold, Platinum, and Diamond) and active-duty U.S. military personnel on orders are also granted the higher 70 lb limit at no extra cost, even when flying in Economy. The standard size limit for all checked bags is 62 linear inches (length + width + height). It is a peer-to-peer "pro-tip" to weigh your bags before arriving at the airport; Delta's fees for bags between 71 and 100 lbs can jump to $200 per bag, making it significantly cheaper to split your belongings into two 50 lb suitcases rather than paying for one "heavy" bag.
