How much baggage can Space-A passengers check?

Each Space-A passenger (regardless of age) can check two pieces of baggage totaling 140 pounds. Air Mobility Command (AMC) limits the size of each item to 62 linear inches. This measurement is obtained by adding together the item’s length, width and height. The rules permit some exceptions to the 62 linear inches size limitation. For Active Duty personnel, all duffel bags, sea bags, Air Force issue B-4 bags and civilian-origin versions that have the same approximate dimensions can be checked. Similarly, the size restrictions do not apply to golf bags with golf clubs, snow skis, folding bicycles, fishing equipment, musical instruments and rucksacks. Any one of these over-sized items listed above may be checked if it is the only piece checked and meets weight requirements of 140 pounds total.
