Air carriers allow you to check a specified amount of personal baggage free of charge. The amount of allowable baggage may be determined either by the number of pieces or the weight of your bags, depending on the air carrier, type of travel and origin or destination. If you check more than the limit, you may need to pay a fee.

For infants under age two who are travelling free or on reduced fares, there is no baggage allowance. For children over age two travelling on reduced fares, the same baggage allowance applies as for adult passengers.

Weight and piece limitations can vary from one carrier to the next and from one size of airplane to another. If you have a connecting flight and the second carrier has a smaller limitation than your initial carrier, you may be required to pay an excess-baggage fee.
