In the transportation area, a company can increase the number of flights on routes, add more cars or consists to a train, move to a larger ship or add ships or containers to a cargo transport. In the telecommunications industry a common carrier may be able to solve an overbooking problem by adding bandwidth—either by adding lines to an existing system, reconfiguring existing lines, upgrading existing lines to a higher speed line or greater number of time-multiplexed lines, or some other scheme to add bandwidth. In the hotel industry, while revenue management teams commonly practice overbooking, they also work to ensure that hotels are not excessively overbooked resulting in negative brand perception and loss in profit.
