Excess baggage is the amount of overweight baggage exceeding the free allotted amount permitted for air travel in number, weight, or size. This may be carried at an additional charge at the airline’s discretion, however there is no guarantee that it will be allowed and might need to be sent as freight instead. Certain airlines impose embargoes on excess baggage for certain routes, and will accept very little or no excess baggage.
Checked baggage refers to baggage which is shipped in the hold of an aircraft or the baggage cart of a train, meaning that it is inaccessible to the passenger during the trip.
Airlines usually limit checked baggage in terms of weight, number and size, and it is normally dependent on the class of ticket or paid fare. Any baggage which exceeds this allotted amount is considered excess baggage. With most discount economy tickets in the U.S. checked baggage is no longer complimentary, and airline carriers require that passengers either travel in a premium cabin, hold an elite status on their airline or hold a full fare economy ticket in order to qualify for complimentary checked baggage.
Unaccompanied baggage is goods which are usually sent separately as personal-effect cargo, and does not accompany a passenger.
Baggage allowance is the total weight of accompanied baggage that a passenger is allowed to check in for a flight by an airline.
Excess Baggage Charges
Excess Baggage Charges are the additional charges levied by the carrier or airline at the airport before the flight embarks in order for a passenger to ship excess luggage to the travel destination/s.
