Most airlines will allow you to check one bag and have one carry-on bag. There is normally a maximum weight limit of 50 pounds per checked bag as well as a size restriction. The most common maximum size bag allowed is 62 linear (total) inches. A common size bag for checking through is: 27 x 21 x 14.

Yes, in 2026, the "50/62 Rule" remains the industry standard for most major international and domestic airlines (like Delta, United, and American). This means each checked bag can weigh up to 50 pounds (23 kg) and its total linear dimensions (Length + Width + Height) must not exceed 62 inches (158 cm). If your bag is 51 pounds or 63 linear inches, you will likely be hit with "overweight" or "oversized" baggage fees, which in 2026 can range from $100 to $200 per bag. A supportive tip for 2026 travelers: always measure from the widest points, including wheels and handles, as modern "automated bag drops" use laser sensors that are unforgiving. If you are flying Business or First Class, many airlines graciously increase the weight limit to 70 pounds (32 kg), but the 62-inch size limit almost always remains the same to ensure the bag fits within the physical constraints of the airport's automated sorting belts.
