Luggage forwarding , also known as luggage shipping or luggage logistics , is a type of speciality shipping service that has been available for approximately 10 years and has grown in demand , particularly after the September 11 , 2001 attacks . Luggage forwarding is an alternative to checking in baggage during air travel . Baggage can also refer to the train of people and goods , both military and of a personal nature , which commonly followed pre-modern armies on campaign . The baggage was considered a strategic resource and guarded by a rear guard . Its loss was considered to weaken and demoralize an army , leading to rearguard attacks such as that at the Battle of Agincourt
