All checked bags must weigh no more than 50 pounds (23 kilograms) for all economy and premium economy fares and 70 pounds (32 kilograms) for business, first and Polaris fares, and must meet maximum linear dimensions of 62 inches ( 158 centimeters). (“Maximum linear dimensions” is simply the number you get when you add the length, width (or height), and depth of a piece of luggage. For example, if you have a suitcase that is 26 inches long, 20 inches wide, and 16 inches deep, then its linear dimensions are 62 inches, or the maximum for many airlines).
